PGPIPN vs Pinealon
Side-by-side comparison of key properties, dosing, and research.
- Summary
- PGPIPN is a bioactive hexapeptide (Pro-Gly-Pro-Ile-Pro-Asn) derived from beta-casein during enzymatic digestion. It exhibits anti-inflammatory properties via opioid receptor modulation and cytokine suppression, making it relevant for gut health, systemic inflammation, and as a component of casein-derived functional foods.
- 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
- Estimated 30-120 minutes (peptide degradation)
- Short (peptides rapidly degraded), but epigenetic/gene regulatory effects persist
- Admin Route
- Oral, Subcutaneous (research)
- SubQ, Oral, Intranasal
