GHRP-6
Clinical evidenceThe original ghrelin mimic, dominant in 2005 but largely replaced by cleaner options by 2015, yet still on shelves for its appetite effect.
What it is
GHRP-6 is a synthetic six-amino-acid peptide and the original of the GHRP class, built in the early 1980s to imitate the hunger hormone ghrelin. It binds the ghrelin receptor and triggers pulsing growth-hormone release, but its signature trait is the strongest appetite stimulation of the whole family.
How it works
It tickles the GHSR receptor to release growth hormone, but it also hits appetite circuits deep in the brain, strongly. That hunger arrives around twenty to forty minutes after an injection, and it is an intrinsic part of the ghrelin-receptor pharmacology, not a dosing mistake. Cortisol, prolactin, and water retention ride along with the hormone pulse.
What people report
- ✦Reliable pulsing growth-hormone release
- ✦A powerful, dependable appetite boost useful for trying to eat big during a bulk
- ✦Among the cheapest options in the growth-hormone secretagogue space
- ✦The mechanism is real and the hormone pulse is reliable
Typical use
Typical use is multiple small daily injections. It was the dominant choice in the 2000s, replaced first by GHRP-2, then increasingly by ipamorelin from 2015 onward.
Dosing reference
No approved dose; it reached phase-2 investigation for growth-hormone deficiency without approval. Grey-market dosing is unregulated. Verify any schedule, especially given the hunger and stress-hormone effects that come with it.
Reference only — not a recommendation. Verify via primary sources.
Watch for
The GH pulse works, but so does the appetite, and both are bundled with cortisol elevation, prolactin elevation, and water retention. Ipamorelin gives a cleaner signal. The surviving legitimately 'wanted' effect here is appetite, not a better growth-hormone profile.

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.
