ghk-cu peptide reconstitution instructions Dosage and Protocol: The 30-Day Cycle GHK-CU — ≥99.2% Purity, COA

Phase 2 documented a clear dose-response: 9.1% at 2.4 mg versus 10.8% at 4.5 mg at 26 weeks (Lau et al., 2021)

TB-500, by contrast, works more systemically

This page, however, covers only the reconstitution math of the lyophilized powder for subcutaneous-style research workflows

The verdict: GHK-Cu for skin, collagen peptides for hair/nails Choose GHK-Cu if: Skin anti-aging is primary goal Want injectable or topical option Focused on wrinkles and firmness Choose collagen peptides if: Want overall beauty benefits Prefer oral supplementation Hair and nails are priority Best peptide combinations and stacks Combining peptides provides synergistic benefits

How to interpret the labs AOD-9604 does not have a clear lab-response marker like IGF-1 for GH-axis peptides
