[1] The peptide has been studied for its potential in mitigating cell aging, inducing protein synthesis, minimizing free-radical damage, preventing bacterial infection, and improving the function of skin fibroblasts
This is a commonly referenced study from 1963 claiming a half-life of 5-6 days: nature.com/articles/198200a0 Although I would not cite it as an authority, the six-day half-life has also made it onto the B12 page in Wikipedia, seemingly unchallenged
It pairs SNAP-8 (acetyl octapeptide-3), a peptide that targets expression-line wrinkles, with GHK-Cu, the copper tripeptide tied to collagen synthesis and skin renewal
Richard Heyer, a dermatologist at the University of Michigan, stated in a 2023 interview with Dermatology Times : "Copper peptides have compelling preclinical biology, but we need well-powered RCTs before we can recommend them with the same confidence as retinoids or established growth factors." This perspective reflects the broader clinical sentiment
Hydroxocobalamin has a higher affinity to the TC II transport protein than cyanocobalamin, or adenosylcobalamin
