Melanotan II vs GHK-Cu

Two skin-category research peptides compared. Here is how the two research peptides compare on class, format and price.

Melanotan II

Melanotan II is a synthetic analogue of alpha-melanocyte-stimulating hormone, a melanocortin-receptor agonist. It is supplied lyophilised in a 10 mg vial for laboratory and in-vitro research use only.

Melanotan II is studied for melanocortin-receptor activity in pigmentation and related research models.

GHK-Cu

GHK-Cu (copper tripeptide-1) is a naturally occurring copper-binding tripeptide, supplied lyophilised in 50 mg and 100 mg vials for laboratory and in-vitro research use only.

GHK-Cu is studied for its role in copper transport, collagen and extracellular-matrix remodelling, and skin-related research models. It is a component of the GLOW and KGLOW research blends.

Which do researchers choose?

Melanotan II and GHK-Cu are two skin-category research peptides compared. The right choice depends on the research question: they differ in class (Melanocortin receptor agonist vs Copper tripeptide-1) and strength (10 mg vs 50 / 100 mg). Both are supplied lyophilised, third-party HPLC tested, and shipped express post Australia-wide for laboratory and in-vitro research use only.
