ghk-cu vs ghk-cu + bpc blend

ghk-cu (S-tier) vs ghk-cu + bpc blend (A-tier). mechanism, trials, evidence boundaries, dosing literature. side-by-side reference.

ghk-cu · tier S

the copper peptide with the strongest skin evidence in the catalog. topical record first, injectable story thinner.

the copper peptide with the strongest cosmetic skin record on the site. the topical evidence is in front; the injectable story is a different conversation.

4,192 genes modulated · half-life plasma: minutes (rapidly peptidase-cleared); the ~12h figure is tissue detectability, not a plasma half-life · skin

ghk-cu + bpc blend · tier A

the surface-and-structure repair pairing. ghk-cu rebuilds skin and collagen, bpc-157 works on connective tissue and gut. component evidence first, fixed-blend trial evidence absent.

two well-characterized repair peptides in one vial. GHK-Cu covers skin, collagen, and dermal remodeling; BPC-157 covers connective tissue, gut lining, and vascular repair. the grade is on each molecule's published evidence, not on any vial.

S + A two strong components, no fixed-blend trial · half-life GHK-Cu: tissue-dependent, ~12 h detectable; BPC-157: short (minutes IV) · healing

at a glance

• ghk-cu: tier S · 4,192 genes modulated
• ghk-cu + bpc blend: tier A · S + A two strong components, no fixed-blend trial
