Skin & Hair Research Peptides
Dermal research is dominated by one compound: GHK-Cu, the copper-binding tripeptide with one of the deepest citation records in the field, spanning collagen and glycosaminoglycan synthesis, extracellular-matrix remodeling, antioxidant response, and follicle-related gene expression.
Around it sit Snap-8, an acetyl octapeptide studied as a SNARE-complex modulator, and the multi-compound GLOW and KLOW research blends, which combine GHK-Cu with repair-oriented compounds for combination studies.

Frequently asked questions
+What is GHK-Cu?
GHK-Cu is a naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) complexed with copper. Its plasma concentration declines substantially with age, which is a large part of why it became one of the most-studied compounds in skin and matrix-remodeling research.
+What is the difference between GLOW and KLOW?
Both are multi-compound research blends built around GHK-Cu. KLOW adds KPV to the combination, bringing an anti-inflammatory tripeptide into the formulation — which is why the two are commonly compared in gut–skin axis study designs.
+What is Snap-8 studied for?
Snap-8 is an acetyl octapeptide studied as a modulator of the SNARE complex, the protein assembly that mediates vesicle fusion and neurotransmitter release. It appears in cosmetic-research literature on expression-related matrix changes.
+Can these be used in cosmetic formulations?
No. These are research reference standards for in-vitro laboratory use only. They are not cosmetic ingredients, not approved for retail formulation, and not for human or veterinary use.
