GHK vs Pinealon
Side-by-side comparison of key properties, dosing, and research.
- Summary
- GHK is the natural tripeptide (Gly-His-Lys) released from human albumin that activates tissue remodeling, collagen synthesis, and anti-aging gene expression. The copper-free form is the biological signaling molecule; it chelates copper in tissue to form GHK-Cu but also has independent biological activity.
- 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
- Extremely short as free peptide; tissue binding extends local effects
- Short (peptides rapidly degraded), but epigenetic/gene regulatory effects persist
- Admin Route
- SubQ, Topical, Oral
- SubQ, Oral, Intranasal
