CJC-1295 DAC is Not FDA-approved. Evidence grade: preliminary. This page is clinically reviewed.

TL;DR / Quick Facts

CJC-1295 DAC is CJC-1295 DAC is the long-acting form of CJC-1295, with a maleimidopropionic acid linker that binds albumin. Half-life is days rather than hours. Not FDA-approved. FDA status: Not FDA-approved. Typical use cases: growth hormone optimization, longevity. Evidence grade: preliminary. Dosing is not established (no FDA-approved protocol). Common side effects: see below. Medriva editorial stance: this compound has limited human evidence; consult a licensed clinician.

What it is

CJC-1295 DAC is a member of the CJC-1295 with Drug Affinity Complex class. CJC-1295 with a DAC linker binds serum albumin, prolonging half-life. Trade-off: less pulsatile GH release than the no-DAC form.

What the evidence says

Evidence for CJC-1295 DAC is preliminary. The bulk of the evidence is from pre-clinical models and small or uncontrolled human studies. Well-controlled phase 3 trials are limited or absent.
