Cytoplasmic iron is stored by ferritin heteropolymers, which consist of heavy (FtH) and light (FtL) chains that rise concomitantly in response to the presence of excessive iron ( Figures 4GI , and Supplementary Figures S3E, F )
Under vigorous physical disruption (e.g., agitation or freezing and thawing) or over time in storage, they can grow into particles that may eventually precipitate

Weeks 6-12: noticeable anti-aging effects This is where GHK-Cu shines: Clear skin texture improvement Visible firmness increase Fine lines reduced 20-40% Wrinkles softened Overall "younger" appearance Others start commenting Specific improvements by area: Face: Nasolabial folds (smile lines) softened Crow's feet reduced Forehead lines less pronounced Under-eye area firmer Jawline more defined Neck: Horizontal neck lines softer Crepey texture improved Firmness increased Less sagging Hands: Skin thickness increased Veins less prominent Age spots may lighten Texture smoother Expected improvements by week 12: Individual variation: Age: Younger skin responds faster Starting condition: More damage = more to improve Dose: Higher consistent doses = faster results Combination: Topical + injectable better Lifestyle: Sleep, diet, sun protection affect results Use SeekPeptides to track your GHK-Cu results timeline with photo comparison tools and progress metrics
