MK-677
An oral growth hormone secretagogue that mimics the action of ghrelin, stimulating growth hormone release from the pituitary gland. Unlike injectable peptides, MK-677 is taken orally and has a long half-life.
Common uses: Growth hormone elevation, Improved sleep quality, Increased lean mass, Bone density support
Ipamorelin
A selective growth hormone secretagogue receptor (GHSR) agonist that stimulates pulsatile growth hormone release without significantly raising cortisol, prolactin, or appetite. Considered one of the safest GH-releasing peptides.
Common uses: Growth hormone optimization, Anti-aging, Lean muscle support, Fat loss, Improved sleep
