Garca, S., Liz, M., Gmez-Reino, J

It also activates proteins known as sirtuins that regulate DNA repair and cellular longevity

Subcutaneous injection delivers the peptide directly into systemic circulation, bypassing first-pass metabolism

Recent studies have found that the GlyNAC complex can correct GSH deficiency, counteract oxidative stress, correct type II diabetes, reduce insulin resistance, enhance muscle strength, and improve cognitive function in older adults, suggesting that it has anti-aging effects [28,29,30]

GHK-Cu activates fibroblasts, enhancing the production of collagen type I and elastin while promoting matrix metalloproteinases (MMPs) to remodel the extracellular matrix by clearing degraded collagen

It helps support normal cellular protection, oxidative-stress defense, and detoxification pathways
