CJC-1295, explained honestly

CJC-1295 is the growth-hormone peptide most often paired with ipamorelin in grey-market “stacks.” Here’s the straight version: what it is, what DAC vs no-DAC means, what the evidence shows, and the safety reality.

What is CJC-1295?

CJC-1295 is a synthetic peptide that acts as a GHRH analogue — it mimics growth-hormone-releasing hormone, prompting the pituitary to release more growth hormone (GH). It’s marketed online for muscle, fat loss, recovery and anti-aging, most often stacked with ipamorelin.

DAC vs no-DAC

  • CJC-1295 with DAC (Drug Affinity Complex) is modified to bind albumin, dramatically extending its half-life so it lasts days — giving a sustained rise in GH/IGF-1.
  • CJC-1295 without DAC (often really modified GRF 1-29) acts briefly, producing shorter GH pulses closer to the body’s natural pattern.

Both versions are unapproved and unregulated regardless of the label.

What the evidence actually shows

CJC-1295 can raise GH and IGF-1 levels in studies — the pharmacology is real. But the physique and anti-aging outcomes marketed online lack rigorous, long-term human trials, and its long-term safety isn’t established. As with any GH-raising compound, chronically elevating growth hormone has its own potential downsides.

The legal & safety reality

CJC-1295 is not an approved medicine. It’s sold as a “research chemical” labelled “not for human use,” the label used to sidestep drug regulation — and it’s banned in sport by WADA. Because it’s unregulated, purity, dose, sterility and identity are unverified. Sustained GH elevation (especially with the long-acting DAC form) can cause fluid retention, joint pain, numbness and effects on blood sugar — part of why real GH therapy is prescription-only and closely monitored.

CJC-1295 vs ipamorelin

They’re marketed as a duo because they work on different parts of the same GH axis: CJC-1295 (GHRH analogue) increases how much GH is released, while ipamorelin (ghrelin-receptor secretagogue) triggers GH pulses. Stacking them compounds the uncertainty, since neither is approved or quality-controlled.

Why we don’t sell it

Chemdu is an information site and doesn’t link you to buy unapproved injectables. For muscle, recovery and healthy aging, the evidence-backed levers — training, protein, sleep, and proper medical care for genuine GH deficiency — are where the real results are, without the grey-market risk.

Frequently asked questions

A synthetic peptide that acts as a GHRH analogue, prompting the pituitary to release more growth hormone. It has been studied but is not an approved medicine and is sold only as an unregulated research chemical.
DAC (Drug Affinity Complex) extends the peptide’s half-life so it lasts days rather than minutes. “No-DAC” CJC-1295 (often modified GRF 1-29) acts more briefly. Both are unapproved and unregulated.
It is not an approved drug. It is sold as a research chemical marked “not for human use” and is banned in sport by WADA. Because it’s unregulated, purity and dose are unverified, and chronically raising GH carries real risks.
CJC-1295 is a GHRH analogue that increases how much GH is released; ipamorelin is a ghrelin-receptor secretagogue that triggers GH pulses. Different parts of the same axis, often marketed together, but both are unapproved.
