A blood test is the only reliable way to determine whether B12 is truly the issue
Understanding GHK-Cu before your first injection GHK-Cu is a naturally occurring tripeptide composed of three amino acids: glycine, histidine, and lysine, bound to a copper ion
Use Cases: When Each Route Fits Topical GHK-Cu -- Localized Skin and Hair Goals The evidence supports topical use for: Facial aging and wrinkle reduction -- the most clinically validated use case, with multiple controlled studies Post-procedure recovery -- documented benefits after CO2 laser resurfacing Hair and scalp health -- community reports describe topical application to the scalp, though controlled hair-specific studies are limited General skin quality -- increased density, thickness, elasticity, and collagen documented in clinical studies Common audience: users primarily targeting cosmetic skin outcomes with the strongest available evidence base and the simplest application method
In contrast, the passive diffusion process of B 12 absorption normally a very small portion of total absorption of the vitamin from food consumption may exceed the haptocorrin- and IF-mediated absorption when oral doses of B 12 are very large, with roughly 1% efficiency
