CJC-1295 with DAC
CJC-1295 DAC, DAC:GRF
Forms: The same modified GRF (1-29) peptide plus a reactive DAC group that binds blood albumin; without DAC it is Modified GRF (1-29), listed separately.
Long-acting GHRH analogue: its DAC group binds blood albumin, so one dose keeps GH and IGF-1 raised for days. Development stopped after phase 2.
Legal status: Never approved; FDA has flagged serious reactions (fast heart rate, vasodilation). Sold as a 'research peptide'; status 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
Developed for GH deficiency and lipodystrophy but never approved. In sport: a 'research peptide' for sustained GH/IGF-1 elevation aimed at fat loss and recovery; there are no controlled efficacy data.
What people seek and what studies show
Used for a sustained rise in GH and IGF-1 aimed at fat loss and recovery. In healthy adults it raised mean GH 2- to 10-fold and IGF-1 1.5- to 3-fold, mostly by lifting GH between pulses while the pulses themselves stayed normal; repeated doses had a cumulative effect. No published study has measured fat, muscle, recovery or performance, so these benefits are assumed from GH effects rather than shown.

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 4 of 8 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).
Limit caffeine and other stimulants; with palpitations, stop the suspected drug and get an ECG. Don't add potassium on your own (supplements, Asparkam/Panangin, salt substitutes): it is dangerous with spironolactone, ARBs/ACE inhibitors or kidney problems; a blood test shows the level.
How each option helps (1)
- Heart screening: ECG and echocardiogram — An ECG reveals arrhythmias, conduction problems and QT changes — important with stimulants, clenbuterol, thyroid hormone or diuretics.
No check-up or blood test lowers this risk; avoid with any personal or family history of cancer.
What is unknown cannot be lowered, only avoided; tell your doctor what you have taken.
Low-level side effects
How each option helps (1)
- Working with a doctor — Tells harmless water retention from swelling due to heart, kidney or liver trouble; steroid labels warn that edema can come with heart failure.
How each option helps (1)
- Working with a doctor — Finds treatable causes of numbness early: low vitamin B12 on metformin, copper deficiency from excess zinc, nerve compression from GH-driven swelling.
How each option helps (7)
- Glucose monitoring — Rising fasting readings reveal insulin resistance from GH or other drugs early.
- Regular blood tests — Fasting glucose, insulin and HbA1c catch rising blood sugar early — key with GH, its secretagogues and insulin.
- Regular cardio training — Improves insulin sensitivity — useful against the blood-sugar rise from GH and its secretagogues.
- Working with a doctor — Interprets glucose markers and treats early metabolic problems.
- Berberine — Meta-analyses: lower fasting glucose and HbA1c (about 0.6% in type 2 diabetes); smaller effect when glucose is normal.
- Alpha-lipoic acid — Small drops in fasting glucose, insulin and HbA1c in meta-analyses; no real counter to GH- or insulin-driven resistance.
- Psyllium husk fiber — Slows sugar absorption: lower fasting glucose and HbA1c, mostly in people with diabetes.
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
- Racing or irregular heartbeat that does not settle at rest, dizziness, fainting, chest pain — call emergency services.
- A new lump (including in the neck), trouble swallowing or persistent hoarseness, unexplained weight loss, or blood in stool or urine — see a doctor promptly.
In an emergency, call your local emergency number.
Myth & fact
“'CJC-1295' on a vial always means the long-acting DAC version.”
The name is also commonly used for Modified GRF (1-29), a short-acting peptide; only the DAC form binds albumin and keeps IGF-1 raised for days.
