Stanozolol injectable suspension
Winstrol Depot, Strombaject, Winstrol-V, Stanozolol suspension, Winstrol injectable
Forms: A water-based suspension (Winstrol Depot, Strombaject; veterinary Winstrol-V). The tablets have their own card.
Other esters and forms: Stanozolol (tablets)
Injectable steroidsControlled substanceWADA S1.1 · prohibitedEvidence: approved medicine
Stanozolol as a water-based injectable suspension. Injection does not remove the 17α-methyl group: like the tablets, it is a DHT derivative that strains the liver and lowers HDL cholesterol.
Legal status: Controlled anabolic steroid in many countries (US Schedule III); the human injection is largely discontinued, veterinary products continue; varies by country.
What it gives
What people use it for and what the sources report. Strength is a general category from the literature: mild, clear or strong.
Purpose
Used while dieting and by power and speed athletes for strength without weight gain and a dry, hard look. The human injection is discontinued in many countries; veterinary use continues.
What people seek and what studies show
Athlete data are few: in weight lifters stanozolol tablets added about as much body weight as injected testosterone while cutting HDL far more. The dry look fits its chemistry: it forms no estrogen. Medically, a single injection before major surgery prevented the usual post-operative fall in the blood's clot-dissolving activity in a small controlled study.

Possible side effects
Possible does not mean certain: whether they appear depends on dose, duration, individual response and monitoring. Below — what to watch for and how to notice it early.
16 possible side effects
level · how often it is reportedElevated
Worse cholesterol (HDL↓ LDL↑)
commonMeasured with the tablets in weight lifters: HDL fell by 33% and LDL rose by 29%. The injection was not studied separately, but it is the same androgen; only a lipid panel shows it.
How to notice: No symptoms — only visible on a lipid panel.
Elevated
Suppression of natural testosterone & fertility
commonSuppresses natural testosterone and sperm production; recovery after stopping can take months, often with low libido and fatigue until then.
How to notice: Lower libido and energy, smaller testicles; after stopping — low natural testosterone on tests, often with tiredness and low mood.
In women: Menstrual changes or missed periods, lower libido and energy; reduced fertility.
Elevated
Black-market quality risk (fakes, contamination)
commonMostly from underground labs; a non-sterile water-based suspension carries a real risk of abscess and infection, and content may not match the label.
How to notice: Unexpected effects, pain or infection, a stronger or weaker effect than expected.
Elevated
Liver strain
possibleInjection skips the first pass through the liver but keeps the 17α-methyl group, and cholestatic hepatitis is reported. Hard training also raises ALT and AST.
How to notice: Usually silent early; later tiredness, nausea, itch, dark urine.
Elevated
Kidney strain
rareRare: severe cholestasis can damage the kidneys (bile cast nephropathy); two bodybuilders needed dialysis after using it.
How to notice: Usually silent; foamy urine or swelling in later stages. Big muscle mass or creatine also raise creatinine.
Moderate
Injection pain, infection, oil cough
commonA water-based suspension: injections are often painful; deltoid muscle breakdown in a bodybuilder, skin necrosis and lasting nodules are reported. Growing redness or swelling needs a doctor.
How to notice: Soreness, lumps; a short coughing fit right after an injection.
Moderate
Joint & muscle pain
possibleJoint aches ('dry joints') are widely reported by users; the cause is not proven — low estrogen may play a role.
How to notice: Aching or stiff joints, muscle aches.
Moderate
Tendon / ligament injury risk
possibleAAS users have markedly more upper-body tendon ruptures (class data, not stanozolol-specific); fast strength gains are one proposed cause.
How to notice: Pain at tendon attachments under heavy load; in steroid-using bodybuilders about a quarter of ruptures followed such pain.
Moderate
Androgenic hair loss
possibleA potent DHT derivative: can noticeably speed up hair loss in genetically prone men.
How to notice: More hair in the shower, thinning at the temples or crown.
Moderate
Thick blood (hematocrit) / clot risk
possibleUsed for some anemias because it raises hemoglobin. Thicker blood plus dehydration (weight cuts, heat) or long trips to events raises clot risk.
How to notice: Often silent; sometimes headaches, flushed face, itch after a hot shower.
Moderate
Heart strain / heart-muscle thickening
possibleNot 'athlete's heart': steroid-using lifters pumped weaker than non-using lifters (LVEF 52% vs 63%) and had more coronary plaque.
How to notice: Shortness of breath on effort, endurance falling for no training reason, palpitations.
Moderate
Irritability, aggression, mood swings
possibleClass data: more aggression is among the effects male athletes on steroids most often report; body dissatisfaction can drive use, and dependence can develop.
How to notice: Short temper, irritability, conflicts with others.
MenLow
WomenHigh
Virilization in women (often irreversible)
commonDespite its 'mild' reputation it readily virilizes women: voice deepening and clitoral enlargement may be permanent.
How to notice: Hoarse or deeper voice, new facial or body hair, menstrual changes, clitoral enlargement.
Low
Too-low estrogen (joints, libido, mood, lipids)
possibleNot aromatized: used without testosterone, it drives estradiol down — low libido, flat mood and joint aches can follow.
How to notice: Aching, stiff joints, low libido, flat mood, poor sleep.
Low
Acne, oily skin
possibleOily skin and acne are possible.
How to notice: Oily skin, spots on back, shoulders and face.
Low
Higher blood pressure
possibleLess fluid than with estrogenic orals, but pressure can still rise; heavy lifts briefly push it far higher. Measure at home at rest, not after training.
How to notice: Often silent; sometimes headaches, flushing, nosebleeds — a home monitor shows it. Heavy lifts briefly spike it even in healthy lifters.

How to lower the risks
For 13 of 16 possible side effects there are specific ways to lower the chance: everyday measures, supplements and options a doctor may consider. For the rest — general advice. No measure removes a risk completely. Prescription medicines are listed only for a doctor to decide on, after tests — they have side effects of their own.
ElevatedWorse cholesterol (HDL↓ LDL↑)
Avoid combining several oral steroids; regular cardio, soluble fiber (psyllium), less saturated fat and alcohol; if LDL/ApoB stay high, a doctor may consider a statin. Omega-3 only lowers triglycerides.
Measure
Supplement or OTC product
Only if a doctor prescribes
How each option helps (13)
- Regular blood tests — A lipid panel with ApoB shows how far HDL has dropped and LDL risen — changes you cannot feel.
- Working with a doctor — Interprets lipids and ApoB and decides whether a statin or other therapy is warranted.
- Avoiding alcohol and other liver stressors — Alcohol raises triglycerides; its small HDL bump does not lower heart risk.
- Regular cardio training — Raises HDL a little and lowers triglycerides; it cannot offset a steroid-driven fall in HDL on its own.
- Berberine — Placebo-controlled meta-analysis: LDL about 0.5 and triglycerides about 0.4 mmol/L lower; HDL unchanged. Trials are mostly small; no statin substitute.
- Citrus bergamot — Pooled small trials show lower LDL and triglycerides, but certainty is low to very low; it is no replacement for statins.
- Omega-3 (fish oil, EPA/DHA) — Lowers triglycerides but does not fix the steroid HDL drop, the main lipid harm; omega-3 supplements may even raise LDL (IOC).
- Psyllium husk fiber — Lowers LDL by about 0.2–0.3 mmol/L (roughly 5–10%), also on top of doctor-prescribed statins; no effect on HDL.
- Atorvastatin — A doctor may consider it when LDL or ApoB stay high; it strongly lowers them but barely lifts steroid-lowered HDL. Risks: muscle aches, drug interactions, rarely muscle or liver injury. Has side effects of its own.
- Rosuvastatin — A doctor may consider it when LDL or ApoB stay high; it strongly lowers them but barely lifts steroid-lowered HDL. Risks: muscle aches, rarely muscle or liver injury, slightly higher diabetes risk. Has side effects of its own.
- Ezetimibe — A doctor may consider it when LDL stays high on a statin or a statin isn't tolerated; it lowers LDL moderately but does not raise HDL. Risks: rare liver-enzyme rises. Has side effects of its own.
- Pravastatin / pitavastatin (low-interaction statins) — A doctor may consider them when LDL is high and other statins aren't tolerated; they lower LDL moderately and barely lift HDL. Risks: muscle aches, slightly higher diabetes risk. Has side effects of its own.
- Icosapent ethyl (prescription EPA) — Lowers triglycerides without raising LDL, unlike DHA-containing oils, but does not fix the steroid HDL drop, the main lipid harm. Has side effects of its own.
ElevatedSuppression of natural testosterone & fertility
Check hormones before and after; if they stay low, see an endocrinologist. Hard training on too little food (RED-S) also lowers testosterone.
Measure
Only if a doctor prescribes
How each option helps (8)
- Regular blood tests — LH, FSH and testosterone show how deep suppression is and whether natural production has recovered afterwards.
- Working with a doctor — Assesses how deep suppression is and guides recovery afterwards, including fertility testing.
- Choriogonadotropin alfa (recombinant hCG) — A doctor may consider it off-label to preserve fertility (it keeps the testes working); it does not restart the pituitary. Risks: higher estradiol, gynecomastia. Has side effects of its own.
- Clomiphene — A doctor may consider it after stopping, guided by hormone tests; most men recover on their own within months, and lasting benefit is unproven. Risks: vision changes, mood swings, rare clots. Has side effects of its own.
- hCG (urinary human chorionic gonadotropin) — A doctor may consider it to preserve fertility (in men it keeps the testes working); it does not restart the pituitary, so natural LH still has to recover. Risks: higher estradiol, gynecomastia. Has side effects of its own.
- Tamoxifen — A doctor may consider it after steroids are stopped, guided by hormone tests; it has not been tested for this after steroid use. Risks: blood clots, vision changes. Has side effects of its own. Not offered to women: in the women’s view it adds to a risk this substance already carries.
- Follicle-stimulating hormone (follitropins, menotropins) — A fertility doctor may consider adding it to hCG when semen tests and FSH stay low; it does not restart the pituitary. Risks: gynecomastia, acne. Has side effects of its own.
- Toremifene — A doctor may consider it after steroids are stopped, guided by hormone tests; it raised testosterone in subfertile men but was never tested after steroids. Risks: QT prolongation, clots. Has side effects of its own. Not offered to women: in the women’s view it adds to a risk this substance already carries.
ElevatedBlack-market quality risk (fakes, contamination)
Products obtained without a prescription are often fake, mislabeled or non-sterile, and there is no way to check at home. For legal supplements, third-party testing (Informed Sport, NSF) lowers, but does not remove, the risk of a positive doping test.
ElevatedLiver strain
No alcohol or other liver stressors, limit oral steroids and their combinations; check liver enzymes (hard training raises ALT and AST too).
Measure
Supplement or OTC product
Only if a doctor prescribes
How each option helps (6)
- Avoiding alcohol and other liver stressors — Removes a major extra liver stressor during oral steroids and other hepatotoxic drugs.
- Regular blood tests — ALT, AST, GGT and bilirubin show liver strain early. Weightlifting raised AST, ALT and CK for at least a week in men new to it, while GGT stayed normal — it helps tell muscle from liver.
- Ademetionine (SAMe) — Used for intrahepatic cholestasis in some countries, but trials are small and of low quality; untested in steroid users. Stopping the oral steroid matters most.
- N-acetylcysteine (NAC) — Restores glutathione; proven in paracetamol poisoning but untested in steroid-related liver injury.
- TUDCA (tauroursodeoxycholic acid) — Improves bile flow in cholestatic disease; in steroid cholestasis only case reports, with failures in severe cases. Stopping the oral steroid matters most.
- Ursodeoxycholic acid (UDCA) — A doctor may consider it to improve bile flow; in steroid cholestasis benefit is unproven and severe cases often did not respond. Stopping the oral steroid comes first. Has side effects of its own.
ElevatedKidney strain
Drink enough, more in heat; control blood pressure; avoid regular painkillers (NSAIDs) and any during long or hot events; no weight cutting by dehydration.
Measure
Only if a doctor prescribes
How each option helps (6)
- Fluid & electrolyte management — Good hydration eases kidney stress from heavy training and heat; dehydration plus NSAIDs is a classic cause of acute kidney injury.
- Regular blood tests — Creatinine runs high with big muscle mass, creatine and hard training, and standard eGFR formulas mislead in athletes; compare with your own baseline and add cystatin C and urinalysis.
- Working with a doctor — Investigates protein in the urine or falling kidney function and can start treatment that slows kidney damage.
- ACE inhibitors (ramipril, perindopril, lisinopril) — May reduce protein in urine and slow kidney disease. But dehydration (weight cuts, heat, ultra-endurance races), diuretics or NSAIDs such as ibuprofen can trigger acute kidney injury. Has side effects of its own.
- Losartan / valsartan (angiotensin receptor blockers) — May reduce protein in urine. But dehydration (weight cuts, heat, ultra-endurance races), diuretics or NSAIDs such as ibuprofen can trigger acute kidney injury. Has side effects of its own.
- Telmisartan — May reduce protein leakage into urine. But with dehydration (heat, weight cuts), diuretics or NSAIDs (ibuprofen etc.) it can trigger acute kidney injury. Has side effects of its own.
ModerateInjection pain, infection, oil cough
Sterile technique, never share needles, vials or pens; see a doctor for a hot, swollen site. If equipment was ever shared, test for HIV and hepatitis B/C and ask about hepatitis B vaccination.
ModerateJoint & muscle pain
Check estradiol (too low hurts joints), warm up well, avoid overloading; pain that grows each session needs a sports physician, not painkillers.
Measure
Supplement or OTC product
How each option helps (2)
- Working with a doctor — Finds the cause of joint or muscle pain — estradiol pushed too low by an aromatase inhibitor, GH-driven swelling, statin muscle effects — so treatment can be adjusted.
- Coenzyme Q10 — May ease statin-related muscle aches (one meta-analysis positive, results mixed); no help for joint pain from low estrogen.
ModerateTendon / ligament injury risk
Progress weights gradually — strength rises faster than tendons adapt; with persistent tendon pain, cut the load and see a sports physician.
ModerateAndrogenic hair loss
Ketoconazole shampoo, minoxidil, a dermatologist early if you are prone to it.
Supplement or OTC product
How each option helps (1)
- Minoxidil (topical) — Slows thinning and regrows some hair; scalp itching and early temporary shedding are common, unwanted facial hair possible. Gains fade once stopped.
ModerateThick blood (hematocrit) / clot risk
Check the blood count regularly; if hematocrit stays high, a doctor decides — usually stopping or reducing the cause, sometimes therapeutic phlebotomy, never blood-bank donation. Dehydration in long or hot sessions and long flights add to clot risk.
Measure
How each option helps (3)
- Regular blood tests — A blood count shows hematocrit and hemoglobin climbing toward the range where clot and stroke risk rises.
- Therapeutic phlebotomy prescribed by a doctor — Only on a doctor's decision, never at a blood bank. Lowers hematocrit quickly but temporarily; repeated sessions drain iron, and a lower clot risk is unproven.
- Working with a doctor — Manages thick blood by changing what you use or, if justified, by therapeutic phlebotomy; dehydration, long flights and injury immobilization add to clot risk in athletes.
ModerateHeart strain / heart-muscle thickening
Regular cardio, blood pressure control, an echo as a baseline and then yearly, read by a cardiologist who knows athletes’ hearts.
Measure
How each option helps (4)
- Heart screening: ECG and echocardiogram — Echocardiography shows wall thickening and reduced pumping early, while stopping AAS and treating BP can still help.
- Working with a doctor — Orders ECG and echocardiography and treats early heart changes.
- Home blood-pressure monitoring — Keeping BP controlled is one of the main ways to limit heart-wall thickening.
- Regular cardio training — Supports heart and vessel function, but does not reverse steroid-related heart thickening or weakening.
ModerateIrritability, aggression, mood swings
Good sleep, fewer stressors, tell someone close what to watch for. About one in three androgen users becomes dependent; if you cannot stop or never feel big enough, talk to a doctor or psychologist.
Measure
How each option helps (2)
- Avoiding alcohol and other liver stressors — Alcohol and other drugs on top of steroids explain much of the link between steroid use and violence.
- Sleep hygiene — Enough sleep lowers irritability and improves impulse control.
MenLow
WomenHigh
Stop at the first voice change and see a doctor — early stopping matters.
Measure
How each option helps (1)
- Working with a doctor — Steroid labels say to stop at the first mild signs (hoarse voice, facial hair, clitoral growth) to prevent permanent change; checks catch them early but do not make use safe.
Low-level side effects
Low estrogen
Avoid controlling estrogen blindly; adjust only by blood tests with a doctor.
Measure
How each option helps (1)
- Regular blood tests — Testing ends guesswork use of aromatase inhibitors — prescription drugs that can push estrogen too low and harm joints, libido, mood and lipids.
Acne
Gentle skin care, cleansing after training, a dermatologist if it spreads.
Supplement or OTC product
How each option helps (3)
- Adapalene — Reduces spots in many users. Redness, scaling, dryness and stinging are common early and usually ease; acne may look worse at first. Rarely, allergic swelling.
- Benzoyl peroxide — A first-line acne option. Dryness, redness and peeling are common at first; it bleaches hair, towels and training clothes; rarely, serious allergy. Severe steroid acne needs a dermatologist.
- Zinc — Trials show a modest drop in inflamed spots, weaker than antibiotics; steroid acne is driven by androgens.
Blood pressure
Less salt, regular cardio, good sleep, home readings; if it stays high — a doctor, and a talk about maximal lifts.
Measure
Supplement or OTC product
How each option helps (19)
- Home blood-pressure monitoring — Persistently high resting readings mean seeing a doctor. For athletes, guidance prefers ARBs or ACE inhibitors, which don't limit exercise capacity; diuretics are banned in sport.
- Regular cardio training — In a meta-analysis of trials, endurance training lowered resting BP by about 8/5 mmHg in people with high BP and only slightly in those with normal BP.
- Working with a doctor — Diagnoses persistent hypertension and prescribes treatment when needed.
- Avoiding alcohol and other liver stressors — Regular drinking raises blood pressure; cutting it out lowers it.
- Coenzyme Q10 — Inconsistent: some analyses show a small systolic drop in cardiometabolic disease, but a Cochrane review found no clinically meaningful effect.
- Magnesium — Meta-analysis of 34 trials in adults, not athletes: about 2 mmHg lower systolic pressure on average.
- Magnesium aspartate — On average magnesium lowers blood pressure only slightly — not a substitute for a doctor's assessment of high pressure found at a sports check.
- Magnesium chloride — On average magnesium lowers blood pressure only slightly — not a substitute for a doctor's assessment of high pressure found at a sports check.
- Magnesium citrate — On average magnesium lowers blood pressure only slightly — not a substitute for a doctor's assessment of high pressure found at a sports check.
- Magnesium gluconate — On average magnesium lowers blood pressure only slightly — not a substitute for a doctor's assessment of high pressure found at a sports check.
- Magnesium glycinate (bisglycinate) — On average magnesium lowers blood pressure only slightly — not a substitute for a doctor's assessment of high pressure found at a sports check.
- Magnesium lactate — On average magnesium lowers blood pressure only slightly — not a substitute for a doctor's assessment of high pressure found at a sports check.
- Magnesium malate — On average magnesium lowers blood pressure only slightly — not a substitute for a doctor's assessment of high pressure found at a sports check.
- Magnesium orotate — On average magnesium lowers blood pressure only slightly — not a substitute for a doctor's assessment of high pressure found at a sports check.
- Magnesium oxide — On average magnesium lowers blood pressure only slightly — not a substitute for a doctor's assessment of high pressure found at a sports check.
- Magnesium taurate — Meta-analysis of trials: about 2 mmHg lower systolic pressure on average — too small to replace a doctor's assessment of high pressure found at a sports check.
- Omega-3 (fish oil, EPA/DHA) — Small drop of a few mmHg, mainly in people with untreated high blood pressure.
- Potassium — Meta-analysis of trials: about 3.5 mmHg lower systolic pressure on average, seen only in people with hypertension.
- Taurine — Meta-analysis of 20 small trials: about 4 mmHg lower systolic pressure on average.

- Yellow skin or eyes, dark urine, pale stools, intense itching, pain under the right ribs — see a doctor now; sudden severe abdominal pain with dizziness or fainting — call your local emergency number.
- Much less urine than usual, cola-colored urine (especially with severe muscle pain after hard training), new swelling, flank pain — see a doctor now.
- Swelling, pain or redness in one leg (especially after a long flight) — urgent care; sudden breathlessness, chest pain, one-sided weakness or numbness, trouble speaking or seeing — call your local emergency number.
- Chest pain or pressure, fainting or near-fainting on exertion, breathlessness on light effort, swollen ankles — stop training and seek urgent care; collapse — call your local emergency number.
- Losing control of anger, thoughts of harming yourself or others — stop and get help today.
- A snap and sudden sharp pain in a tendon, inability to load the limb — stop training and get it examined.
- A hot, red, swollen or pus-filled injection site with fever — signs of an abscess; see a doctor.
- Deepening voice, new facial hair, clitoral enlargement — stop and see a doctor: changes can become permanent. (women)
In an emergency, call your local emergency number.
For women
Often presented to women as a 'light' option, but it is a strong androgen for women: voice deepening, facial hair and clitoral enlargement are common and may be permanent; risk rises with dose and duration. Androgens virilize a female fetus, so they are ruled out in pregnancy.
Myth & fact
Myth
“Injectable Winstrol spares the liver.”
Fact
Both forms carry the same 17α-methyl group that makes it liver-active. Injection skips the first pass but does not make it liver-safe — liver tests and lipids still need watching.
Combinations
No specific combination notes for this substance yet. The stack check still adds up side effects that several substances share.
