AHK-Cu is a copper tripeptide with one published study showing hair follicle stimulation in vitro. Community use is mostly topical at 0.5 to 1% concentration. Injectable protocols exist but lack any direct scientific backing beyond structural similarity to GHK-Cu, which carries a far broader published evidence base.

Reconstitution math for injectable use: a 5 mg vial with 1 mL bacteriostatic water gives you 5,000 mcg/mL. On an insulin syringe, 2 units equals 100 mcg (beginner dose) and 5 units equals 250 mcg (moderate dose). A 5 mg vial lasts 20 days at the moderate dose. With a 50 mg vial and 2 mL bacteriostatic water, you get 25,000 mcg/mL; 1 unit equals 250 mcg. The powder should be blue-green. If it's white or colorless, the copper chelation probably didn't happen and you're injecting a plain tripeptide. Always check the Certificate of Analysis for HPLC purity and amino acid composition. Most AHK-Cu on the market is cosmetic-grade. If you're injecting, confirm the vendor offers injectable-grade product with endotoxin testing. This matters more than price. Don't apply AHK-Cu right after a vitamin C serum. The low pH destroys the copper complex on contact. Split them AM and PM, or wait at least 30 minutes between applications. Store reconstituted vials at 2 to 8 degrees Celsius. Use within 2 to 3 weeks. Discard if the solution changes color or shows particles.
