Peptide clears from blood BUT cellular processes continue Duration of cellular effects: Why this matters: Don't need continuous high levels in blood Single injection triggers multi-day effects 2-3x weekly dosing sufficient (not daily required) Cellular "memory" of GHK-Cu exposure Cumulative effects with repeated dosing: Each dose builds on previous Collagen accumulation over weeks Tissue remodeling compounds Results improve with consistent use Comparing GHK-Cu to other peptides Half-life comparison table: GHK-Cu positioning: Short half-life like Ipamorelin But longer cellular effects than half-life suggests Middle-ground dosing frequency (not daily, not weekly) Cumulative benefits with consistency See our BPC-157 guide , TB-500 guide , peptide dosing guide , and peptide dosage chart

For external use, you can apply a small amount directly to your skin after cleansing, though internal consumption through EVOO provides more comprehensive benefits due to the natural fat matrix that enhances absorption
To choose a supplement, look for hydrolyzed collagen from a trusted source, third-party testing, and minimal additives
