Vitamin C is a powerful antioxidant that helps protect skin from environmental damage while supporting collagen production
GHK-Cu (copper peptide) for skin GHK-Cu (glycyl-L-histidyl-L-lysine-copper) is a copper peptide studied for collagen support, antioxidant effects and wound healing
Polymeric nanoparticles represent another critical category and include cellulose and chitosan nanoparticles
Neuroprotection: Some studies indicate that thymosin beta-4, and by extension TB-500, may have neuroprotective effects, potentially aiding in the recovery from neurological injuries like stroke or traumatic brain injury by promoting neuronal survival and regeneration
BPC-157 is a synthetic pentadecapeptide derived from a sequence identified in gastric juice
In both animal models and controlled human studies, DSIP has been associated with modulation of endogenous sleep-regulating systems rather than direct sedative activity, supporting its classification as a neuromodulator rather than a pharmacological hypnotic agent [2]
