GHK-Cu and NAD+ work through independent mechanisms and don't interfere with each other
How Blue Copper Peptide Fights Skin Aging: The Science 01 Collagen Synthesis (Reconstructing Dermal Support) : Within 6 to 8 weeks of use, it regulates gene expression of Type I and Type III collagen in fibroblasts, improving firmness and reducing fine lines

Commonly Reported Research Observations Mild administration-site redness or irritation Temporary swelling or warmth sensations at the administration site Mild burning or stinging sensations during administration Temporary skin-sensitivity variability Temporary itching- or histamine-related skin-response variability Mild headache-related observations Temporary fatigue- or tiredness-related observations Mild nausea- or digestive-related observations Temporary muscle soreness or recovery-related sensitivity GHK-Cu Related Research Considerations Because Glow Blend contains GHK-Cu, some research settings may observe: Temporary blue-tinted discoloration beneath the administration area Copper-related biomarker variability in higher-frequency protocols Increased skin sensitivity in sensitive research models Tissue-Repair & Recovery Research Considerations Research involving Glow Blend commonly investigates tissue-maintenance and regenerative pathways

The expected dose for the standard 50/10/10 milligram GLOW blend lands in the range of 250 to 600 micrograms of BPC-157 daily, with proportional GHK-Cu and TB-500
Start with low doses of both when combining
Here, we observed that WECP could promote hair growth in mice (Figure 1), stimulate DPCs proliferation and migration, and accelerate the DPCs cell cycle in vitro (Figure 2)
