Growth Hormone Peptides
A research guide to growth-hormone-releasing hormones, secretagogues and related compounds. Compare mechanism, pharmacokinetics, evidence quality, monitoring and regulatory status without treating different molecules as interchangeable.
Educational research reference only, not medical advice. Evidence strength and regulatory status vary substantially between compounds.
8 research profiles
CJC-1295
CJC-1295 is a growth-hormone-releasing hormone analog. The single most important distinction is whether the product has DAC. No-DAC products behave like short GHRH pulses; DAC products bind albumin and last for days.…
Read profile →GHRP-6 & GHRP-2
GHRP-2 and GHRP-6 are ghrelin-receptor agonists that stimulate growth-hormone release. They can also affect hunger, prolactin, cortisol, glucose, and water retention. Evidence lens: The endocrine mechanism is real, but…
Read profile →Hexarelin
Hexarelin, also called examorelin, is a synthetic GH secretagogue in the GHRP family. It is known for strong GH release and potential cardiovascular research interest. Evidence lens: The mechanism is stronger than the…
Read profile →HGH Fragment 176-191
HGH Fragment 176-191 is a short C-terminal portion of the growth hormone molecule promoted for fat metabolism. It is not full growth hormone and should not be treated as the same product as AOD-9604. Evidence lens: Many…
Read profile →IGF-1 LR3
IGF-1 LR3 is a modified insulin-like growth factor designed to last longer and bind IGF-binding proteins differently than native IGF-1. It is discussed for muscle growth and recovery, but the biology also overlaps with…
Read profile →Ipamorelin
Ipamorelin is a ghrelin-receptor agonist used to stimulate GH release with less cortisol and prolactin spillover than older GHRPs. Evidence lens: It is cleaner than GHRP-2/GHRP-6 pharmacologically, but not FDA-approved…
Read profile →Sermorelin
Sermorelin is the first 29 amino acids of growth-hormone-releasing hormone. It stimulates the pituitary to release growth hormone, so it requires a responsive pituitary rather than bypassing the axis like direct hGH.…
Read profile →Tesamorelin
Tesamorelin is an approved GHRH analog used to reduce excess visceral abdominal fat in adults with HIV-associated lipodystrophy. It is not simply a generic belly-fat peptide for everyone. Evidence lens: The approved…
