CJC-1295
Limited human dataTwo different molecules share this name — one lasts a week, the other clears in 30 minutes.
What it is
CJC-1295 is a modified GHRH fragment, engineered with a few amino-acid swaps to resist breakdown. It comes in two very different forms: one with a linker that binds albumin and lasts 6-8 days, and a 'no-DAC' version that clears in about 30 minutes. They are not interchangeable, and neither is FDA-approved.
How it works
It activates the GHRH receptor on the pituitary, prompting a release of growth hormone. The long-acting DAC version drives GH up and keeps it there for days. The short version gives a cleaner natural pulse, especially when paired with a ghrelin-receptor peptide like ipamorelin.
What people report
- ✦Raises growth hormone and IGF-1 output
- ✦Most common GH-axis stack in peptide clinics when paired with ipamorelin
- ✦Deeper sleep is the most consistent reported win
- ✦Modest body-composition shifts over months
Typical use
Usually injected a few times weekly, combined with ipamorelin, for weeks-to-months protocol blocks.
Dosing reference
Community doses range around a few hundred micrograms to a milligram per injection. No approved dose.
Reference only — not a recommendation. Verify via primary sources.
Watch for
The long-acting DAC version fell out of favor in the community over fluid retention and suspected receptor dulling from continuous signaling. A phase-2 volunteer died of a heart attack during a 2006 trial — ruled not drug-related, but the program was shelved. No phase 3 ever ran.
Notes
Strong on mechanism and phase-1 data, thin on long-term proof — the missing FDA approval is the ceiling.

BPC-157
Healing & recoveryThe repair peptide everyone in the gym talks about — powerful in rats, still unproven in humans.
BPC-157 is a short chain of 15 amino acids. It is not a natural hormone your body makes on its own. It was built in a lab as a fragment of a larger 'body protection compound' first found in human stomach juice in the 1990s. Vendors sell this engineered piece, not a natural sequence.
How it works (optional detail)
In animal studies, BPC-157 seems to nudge faster blood-vessel growth at injured spots, which is the body's first step in healing. It also appears to quiet inflammation. The idea is that by tickling repair pathways rather than ordering one single thing, it helps tendons, ligaments, and gut lining recover speedier than they would on their own.
Dosing reference: Common community dosing is a few hundred micrograms a day, usually injected near the site or into belly fat. There is no approved human dose.
