Muscle Growth

Peptides researched for lean mass accrual, myofibrillar protein synthesis, and skeletal-muscle hypertrophy signalling. This goal page collects compounds investigated across GH-axis secretagogues (ipamorelin, CJC-1295, hexarelin), IGF-1 splice variants (IGF-1 LR3, IGF-1 DES), and myostatin-pathway modulators — spanning preclinical anabolic data through to clinical body-composition endpoints.
