Pal-AHKGrowth Hormone Peptides
Ipamorelin- Summary
- Pal-AHK is the palmitoylated form of the AHK-Cu copper tripeptide, created by attaching a palmitic acid chain to enhance skin penetration and lipid bilayer affinity. The palmitoyl modification significantly improves dermal bioavailability compared to unmodified AHK, making it particularly effective in anti-aging and hair growth formulations.
- Ipamorelin is a selective GHRP (growth hormone releasing peptide) and one of the cleanest GH secretagogues available. It selectively stimulates GH release without significantly raising cortisol, prolactin, or appetite — making it ideal for long-term use and anti-aging protocols.
