Why These Three

GHK-Cu is the skin pick, and the logic is simple: this copper-binding tripeptide circulates naturally in plasma, its level falls sharply with age, and Loren Pickart’s work tied it directly to collagen production and tissue remodeling. MOTS-c covers energy. It’s a peptide encoded by mitochondrial DNA, and since a landmark 2015 metabolism paper it has become the compound exercise researchers reach for. Selank is the stress pick, a Russian anxiolytic peptide that went through actual human anxiety trials, which is more than most compounds in this category can claim.

Common Questions

Are these third-party tested?

Yes. Each vial ships against a signed certificate of analysis from an outside lab, matched to the batch number printed on the label. Check the match before the vial goes anywhere near a protocol.

What do they cost?

GHK-Cu is $29.99 for a 50mg vial, MOTS-c runs $39.99 for 10mg, and selank is $29.95 for 10mg. All three together cost less than a single vial of some GH-axis peptides. Current Amino Club prices, checked today.

What about fakes?

GHK-Cu is the most copied of the three because skincare demand keeps prices up. A blue tint proves nothing about copper content. The COA does.
