I cannot recommend this institution more highly, they are stellar in every way
Lifestyle shifts: Exercise, stress reduction (meditation, breathwork), sleep hygiene, toxin avoidance (e.g., mold, chemicals) all matter
Upregulated: collagen synthesis genes (COL1A1, COL3A1), antioxidant genes (SOD1, SOD3), DNA repair genes (GADD45A) Downregulated: inflammatory cytokines (IL-6, TNF-), metalloproteinases (MMP-2, MMP-9), pro-fibrotic mediators Net effect: shift from tissue destruction and inflammation toward repair and remodeling This breadth of gene modulation is unusual for a single tripeptide and has generated significant research interest in fields ranging from dermatology to neuroscience
Part 3: Claims & Verification Claim 1: GHK-Cu is an endogenous peptide with regenerative and anti-inflammatory properties, and its systemic levels decline with age
