Replenishing the nutritional status of the host by increasing vital amino acids such as cysteine to enhance GSH levels and selenium to improve selenium deficiency and facilitate selenoprotein (GSH peroxidases, thioredoxin reductases) expression can inhibit oxidative stress, modulating inflammation, suppressing endothelial dysfunction, and protecting vascular cells against apoptosis and calcification (He et al., 2017
The combination of BPC-157 and GHK-Cu may offer even greater therapeutic benefits

Poor quality peptide from an unreliable sourcealways request third-party testing certificates (COAs) and check for the characteristic faint blue color Improper storage degraded the peptideif the solution has turned dark blue, green, or cloudy, it's likely degraded Dose too low for your goalsif you've been at starting dose for 4+ weeks with zero changes, consider moving to standard dose Not supporting the processGHK-Cu signals collagen production, but your body needs vitamin C, protein, and good nutrition to actually build it Unrealistic expectationsGHK-Cu improves skin quality and healing, but it won't replicate a facelift or completely erase deep wrinkles Key Research [1]"The human tri-peptide GHK and tissue remodeling" Pickart L, 2008 Finding: This comprehensive review showed GHK-Cu activates a wide range of tissue repair processesattracting repair cells, boosting collagen and elastin, increasing blood vessel growth factors (VEGF), and stimulating hair follicle enlargement
