Evaluation of: Glycerol production (a marker of lipolysis) 2-deoxyglucose uptake (a marker of insulin signaling) DNA synthesis (a marker of proliferation) What they found: AOD-9604 stimulated lipolysis dose-dependently from 10 M, with a plateau at 10 M Full hGH stimulated lipolysis to a similar maximum, but with different kinetics AOD-9604 did not affect glucose uptake or DNA synthesis at all, whereas hGH inhibited both (the classic lipotoxic GH effect) Fragments with different sequence (from the N-terminal part of hGH) had no lipolytic effect Why it matters: This was the first publication of AOD-9604

This broad gene-level effect suggests GHK-Cu may influence healing at a more fundamental level than peptides with narrower mechanisms

Semaglutide injections are meant to be subcutaneous, which means below the skin but above the muscle, and not in a vein

Innovations like sliding-fee clinics, global procurement consortia, and technology-transfer grants can enhance reach
