Peptides that stimulate endogenous growth hormone production through secretagogue and releasing pathways.
Most researched peptides
Peptides with the broadest research coverage across multiple health goals.
Somatropin
Somatropin is FDA-approved recombinant human growth hormone identical in sequence to endogenous pituitary GH, used clinically for GH deficiency, Turner syndrome, Prader-Willi syndrome, and other approved indications. In wellness and performance contexts it is studied for body composition, anti-aging, and recovery, though off-label use raises significant regulatory and safety considerations.
View profileCJC-1295
A modified GHRH analog designed to prolong endogenous GH pulse support through albumin binding (DAC form).
View profileIpamorelin
A selective ghrelin-receptor agonist studied for stimulating GH release with less prolactin/cortisol impact than older GHRPs.
View profileMK-677
An oral non-peptide ghrelin receptor agonist often discussed with GH peptides due to GH/IGF-1 stimulating effects.
View profileGHRP-2
A potent synthetic GH secretagogue with human endocrine data demonstrating acute GH pulse stimulation.
View profileCJC-1295 (No DAC)
CJC-1295 without DAC (also called Modified GRF 1-29) is a GHRH analog with a shorter half-life than the DAC version, making it preferred for mimicking pulsatile physiological GH release when administered with a GHRP. It is widely used in research and wellness contexts for GH optimization.
