Research Overview
HGH Fragment 176-191
This 16-amino-acid fragment specifically targets adipose tissue via beta-3 adrenergic receptors. Works through a GH-receptor-independent pathway, explaining selective fat-loss properties without growth-promoting effects.
Ipamorelin
Ipamorelin has moderate clinical evidence. Phase II trials demonstrate selective GH release. Generally regarded as one of the safest GH secretagogues with minimal side effect profile.
