01 — Overview
What are growth hormone peptides?
Growth hormone secretagogues stimulate the body's natural GH production. Includes GHRPs (Ipamorelin, GHRP-6), GHRHs (Sermorelin, CJC-1295, Tesamorelin), and oral options like MK-677. Researched for body composition, recovery, sleep quality, and longevity.
02 — Mechanism
How do they work?
Each compound in this category targets a specific biological pathway — receptor agonism, enzyme modulation, or cellular signaling. The mechanisms drive both the benefits and the side-effect profile, so understanding them is essential before designing any research protocol.
03 — Considerations
What to consider
Source matters. Always verify Certificate of Analysis (COA), storage conditions, and reconstitution protocol. Cross-reference half-life with dosing frequency, and review existing clinical data before extrapolating between research models.
