What is the difference between GLOW and KLOW?
GLOW's three components, with KPV added, is KLOW. Note that a blend's milligram figure covers everything in the vial together rather than any single component. Each of them is sold separately too.
What research has been published?
For GHK-Cu the record is reviews and gene-expression analysis (PMID 29986520, PMID 26236730). Melanotan II turns up in medicinal chemistry as a scaffold for building selective melanocortin receptor agonists (PMID 35188390). Neither GLOW nor KLOW has ever been studied as a blend.
Skin & Pigment questions
Does an 80mg blend mean 80mg of one compound?
It does not. That is the whole vial added up. For the split between components, see the product page.
What does the Cu in GHK-Cu mean?
The copper, held inside the molecule itself rather than sitting alongside it.
