Capromorelin for Muscle Gain
Oral non-peptide ghrelin-receptor agonist; FDA-approved as a veterinary appetite stimulant.
Why Capromorelin for muscle gain?
Capromorelin is a small-molecule ghrelin agonist (GHSR1a) approved by the FDA for appetite stimulation in dogs (Entyce, 2016) and cats (Elura, 2020). Human Phase 2 trials in elderly sarcopenia showed modest gains in tandem-walk and lean mass before development was halted.
Muscle Gain context: Increasing lean mass via GH/IGF-1 axis, satellite-cell activity, or anabolic signaling. Capromorelin fits this goal because its category (Performance) and benefit profile align with the underlying mechanism.
Benefits relevant to muscle gain
