Glutathione
L-glutathione, Reduced glutathione, GSH, TAD 600, TAD600, Tationil, Glutatione, Glutathione reduced
Forms: Capsules, lozenges and liposomal forms; topical creams; injectable reduced glutathione (TAD 600) and compounded IV 'drips'.
The body's main cellular antioxidant, a tripeptide. Sold as a 'liver' and 'detox' supplement and injected for skin lightening; injectable forms are approved only for narrow medical uses.
Legal status: Oral forms are sold as supplements; injectable glutathione is a prescription medicine in some countries. WADA bans large-volume IV infusions outside hospital care (M2.2). 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
Found in 'liver support' formulas for athletes and injected as a liver or 'detox' agent. No study has tested it in steroid users. Injectable glutathione is approved in some countries to prevent cisplatin nerve damage or for alcoholic liver disease.
What people seek and what studies show
Whether oral glutathione is absorbed is debated: in a 4-week trial blood levels did not change, while in a 6-month trial levels in blood cells and plasma rose 30–35% at the higher dose and fell back after stopping. In an open-label pilot in fatty liver (29 patients), average ALT fell. Small trials show modest skin lightening with oral or topical forms; IV use rests on one weak 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.

How to lower the risks
For 1 of 4 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.
Products obtained without a prescription are often fake, mislabeled or non-sterile, and there is no way to check at home. For legal supplements, look for third-party testing (Informed Sport, NSF).
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.
What is unknown cannot be lowered, only avoided; tell your doctor what you have taken.
Drink enough water, control blood pressure, avoid regular painkillers (NSAIDs).
How each option helps (3)
- 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 reads high in muscular people and with creatine; cystatin C and a urine test give a truer picture of the kidneys.
- Working with a doctor — Investigates protein in the urine or falling kidney function and can start treatment that slows kidney damage.
Check-ups and blood tests
Which tests and check-ups to do and when. This is a guide — agree the exact schedule with your doctor.
Which doctors can help
Get medical help at once if
- Much less urine than usual, cola-colored urine, new swelling, flank pain — see a doctor now.
- A hot, red, swollen or pus-filled injection site with fever — signs of an abscess; see a doctor.
In an emergency, call your local emergency number.
Myth & fact
“Glutathione drips detox the liver while on steroids.”
No study in steroid users shows this. The approved injectable uses are narrow, and IV drips have their own risks: contaminated products, infections and severe skin reactions.
