Lean mass, strength, and growth-hormone support.
Ranked below. Evidence is the strength of the human science; Reported is how loud and consistent the community signal is — not proof. When they disagree, that gap is the point.
- 1CJC-1295GHRH analogcommunity
Raises how much GH each pulse releases; near-universal in stacks.
Evidence5/10Reported8/10 - 2IpamorelinGrowth-hormone secretagoguecommunity
Clean GH-pulse trigger; the other half of the stack.
Evidence5/10Reported8/10 - 3TesamorelinGHRH analog (visceral fat)clinical
Approved GH-axis drug; raises IGF-1 and lean mass.
Evidence7/10Reported5/10 - 4SermorelinGHRH analog (GH secretagogue)community
GH releaser with a real clinical history.
Evidence6/10Reported6/10 - 5GHRP-2Growth-hormone-releasing peptide (secretagogue)community
Strong GH pulse, with an appetite bump.
Evidence5/10Reported6/10 - 6IGF-1 LR3Long-acting IGF-1 analog (muscle growth)animal-only
Long-acting IGF-1; popular in bodybuilding, animal data.
Evidence3/10Reported7/10 - 7GHRP-6Growth-hormone-releasing peptide (secretagogue)community
Older GH releaser; big hunger spike.
Evidence4/10Reported5/10 - 8IGF-1 DESTruncated IGF-1 analog (muscle)animal-only
Localized IGF variant; fringe, animal data.
