MK-677 (Ibutamoren)

While technically a growth hormone secretagogue rather than a peptide, MK-677 orally stimulates GH release through the ghrelin receptor. Popular for its convenience and effectiveness in promoting muscle growth.
CJC-1295 + Ipamorelin

This powerful combination stimulates natural growth hormone production. CJC-1295 extends the half-life of GH release while Ipamorelin triggers precise GH pulses, mimicking natural patterns.
