ghk cu pharmaceutical grade GHK-Cu Topical Serum: Benefits, Mechanism & Research Guide GHK-Cu Raw Powder (Topical) Copper-Tripeptide

MMP-1, MMP-2, MMP-9 GHK-Cu has been shown to suppress matrix metalloproteinases (MMPs) that degrade collagen and elastin, preserving dermal structural integrity

That's where AHK-Cu becomes synergistic: growth hormone peptides stimulate procollagen production, and AHK-Cu provides the copper required for lysyl oxidase to cross-link that procollagen into stable, mature collagen fibers

For Research Use Only:Not for human consumption or medical use

Applying it topically, however, creates a completely different kinetic profile
