Research

A research-grounded look at the peptides most commonly discussed in physical optimisation communities — GHK-Cu, BPC-157, and GLP-1 compounds — separating mechanistic evidence from extrapolation.

A deep-dive into Body Protection Compound-157 — the synthetic pentadecapeptide derived from human gastric juice protein with the most extensive preclinical evidence base of any research peptide.

Why researchers combine peptides rather than use them in isolation — the mechanistic rationale for stacking, with a detailed look at the Clavicular Stack protocol that pairs BPC-157, TB-500, and GHK-Cu.
