Skin and Tanning Peptides

Skin and tanning peptides cover two research areas: pigmentation through the melanocortin receptors, and skin structure through copper peptides and cosmetic peptides. Every product is lyophilized or supplied as raw powder and tested to over 99% purity.

Pigmentation research
Melanotan I is more selective for MC1R, the receptor that triggers eumelanin. Melanotan II acts on several melanocortin receptors, and PT-141 is its metabolite with a central receptor profile.

Skin structure research
GHK-Cu and GHK basic are studied for collagen and remodelling, Snap-8 for expression lines, and glutathione for oxidative stress and pigmentation. GLOW and KLOW combine GHK-Cu with repair peptides.

In this collection: GHK-Cu 50mg, GLOW Blend 70mg (GHK-Cu, TB-500, BPC-157), GHK-Cu Raw Powder (1 Gram), PT-141 15mg (Bremelanotide), Melanotan II 17mg, Melanotan I 13mg, GHK Basic 50mg (Copper-Free), Snap-8 10mg, PT-141 10mg (Bremelanotide), Glutathione 600mg, AHK-Cu Raw Powder (1 Gram), KLOW Blend 80mg (GHK-Cu, KPV, TB-500, BPC-157), GLOW Blend 50mg (GHK-Cu, TB-500, BPC-157).

What is the difference between Melanotan I and II?
Melanotan I is linear and more MC1R-selective. Melanotan II is cyclic and acts on more melanocortin receptors.

Are these for topical use?
GHK-Cu powder, AHK-Cu powder and Snap-8 are suited to topical formulation research. The rest are lyophilized vials for laboratory research.

All products are sold for laboratory research use only. Not for human or veterinary use.
