Ipamorelin 5mg
Performance
$89
Selective growth hormone secretagogue with minimal cortisol or prolactin side effects. Promotes GH pulses for lean muscle, fat loss, recovery, and sleep quality.
Overview
Ipamorelin is a selective pentapeptide growth hormone secretagogue that mimics ghrelin to stimulate pulsatile GH release from the pituitary. Unlike GHRP-2 or GHRP-6, ipamorelin does not significantly raise cortisol, prolactin, or appetite, making it one of the cleanest GH secretagogues available. It is frequently paired with CJC-1295 to amplify and extend GH pulses.
