<![CDATA[GHK-Cu — the collagen peptide with the most real science behind it]]>GHK-Cu (copper peptide) is one of the most researched peptides for tissue remodeling. The legitimate scientific literature is substantial — it's used in dermatology, wound healing, and hair restoration with real clinical backing. Here's what GHK-Cu actually does that's established:

Stimulates fibroblast production of collagen types I and III

Promotes elastin synthesis

Increases hyaluronic acid production

Has anti-inflammatory effects

Promotes angiogenesis (new blood vessel formation)

In skin tissue this produces measurable thickening and improved elasticity. The interest in applying this to penile tissue is the collagen thickening mechanism — penile tissue contains collagen and fibroblasts that theoretically respond to the same signaling. Whether practical tissue thickening results are achievable through topical or injected GHK-Cu in penile tissue — there's essentially no formal research. What exists is anecdotal community reporting.
