Carnosine vs BPC-157
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Carnosine is an endogenous dipeptide (beta-alanine + histidine) found in high concentrations in muscle and brain. It is a potent anti-aging molecule with broad spectrum antioxidant, anti-glycation, anti-carbonylation, and metal chelating properties, making it one of the most protective naturally occurring dipeptides.
- BPC-157 is a synthetic pentadecapeptide derived from a protective protein found in the stomach. It is one of the most extensively researched healing peptides, known for accelerating tissue repair, reducing inflammation, and protecting the gastrointestinal tract.
- Half-Life
- ~1.5 minutes (rapidly hydrolyzed to beta-alanine and histidine by carnosinase in blood; tissue levels maintained via constant synthesis)
- 4–6 hours
- Admin Route
- Oral, Topical
- SubQ, IM, Oral
