Growthmaxxing — GH Secretagogues & IGF-1 Peptides

Growthmaxxing — GH secretagogues and IGF-1 peptides: Ipamorelin, CJC-1295, Sermorelin, IGF-1 LR3.

Growthmaxxing is the term this catalog uses for the GH secretagogue and IGF-1 peptides used in growth and recomposition research. Growth hormone secretagogues drive endogenous GH release through two distinct receptor systems: GHRH analogues that bind the growth-hormone-releasing-hormone receptor (Sermorelin, CJC-1295, Tesamorelin) and ghrelin-receptor agonists that mimic the GH-stimulating action of ghrelin (Ipamorelin, MK-677, Hexarelin). The IGF-1 analogues catalogued here — IGF-1 LR3 and Long R3 variants — sit downstream of the GH axis and have been studied for their direct anabolic effects on muscle satellite cells in published preclinical work. This page tracks vendor pricing, vial-size variants, and COA practice for the secretagogues and IGF-1 peptides currently offered across our monitored vendors. Each compound's own page summarises the published mechanism and the strongest research findings to date.
