Pal-AHK vs Pinealon
Side-by-side comparison of key properties, dosing, and research.
- 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.
- Pinealon is a synthetic tripeptide (Glu-Asp-Arg) developed by the St. Petersburg Institute of Bioregulation, designed to penetrate the blood-brain barrier and exert neuroprotective, neurogenic, and anti-aging effects by regulating pineal gland and brain cell function.
- Half-Life
- Extended (lipid depot effect in stratum corneum)
- Short (peptides rapidly degraded), but epigenetic/gene regulatory effects persist
- Admin Route
- Topical
- SubQ, Oral, Intranasal
