CJC-1295 / Ipamorelin
MuscleGrowth-hormone secretagogue combination studied for stimulating endogenous GH pulses in research contexts.
GHRP-2
MuscleGrowth Hormone Releasing Peptide-2. Synthetic hexapeptide ghrelin-receptor agonist. Stimulates GH release potently and consistently. Studied since the 1990s; approved in some Asian markets for diagnostic GH stimulation, NOT for therapeutic use in the US.
Hexarelin
MuscleSynthetic hexapeptide growth-hormone secretagogue developed in the 1990s. Stimulates GH release potently in short-term human studies. Concerns about tachyphylaxis (tolerance) with chronic use have limited clinical development.
