Research Overview
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.
GHRP-6
GHRP-6 has solid pre-clinical and clinical evidence for GH stimulation. Well-characterized pharmacology. More appetite stimulation than Ipamorelin due to ghrelin receptor activation.
