BPC-157 vs GHK-Cu
Compare the research, key figures and safety notes.
How they differ
Both are recovery peptides, but they do unrelated jobs. GHK-Cu is a copper-carrying peptide looked at for skin and connective tissue, gone within about an hour; BPC-157 is a gut-derived peptide looked at for tendon and gut repair over a few hours. Neither has a human dosing trial — GHK-Cu's human evidence is creams, BPC-157's is animal studies — so injected amounts come from the community.

These amounts and schedules are figures discussed in research and community reports, shared for learning — not a recommendation and not medical advice. A step-by-step dosing schedule exists only where a human trial backs it; the evidence tier tells you which.
Decay curves, overlaid
Each line is scaled to that compound's own first dose, so the chart shows how each one builds up over time — not how the compounds' doses compare to one another, which these different molecules share no common unit for.
How they combine
Educational reference on commonly-discussed combinations, not medical advice. Combining compounds can change how each behaves — read this as a prompt to research, not a clearance.
