Topical Application Tips

Apply to clean, dry skin before heavier creams. Avoid combining with strong oxidizers (benzoyl peroxide, low-pH vitamin C). The blue-green tint is normal. No cycling required for topical use.

Injectable Protocol

Reconstitute with bacteriostatic water using the peptide calculator. Research protocols run 4–8 weeks. For hair growth, intradermal injection into the scalp at 50–200 mcg weekly is sometimes combined with microneedling.
