Longevity Blend Calculator
The Longevity Blend is a community term for a combined vial containing MOTS-c, Epithalon, and NAD+. These three compounds are dosed at very different mass scales (NAD+ in tens-to-hundreds of mg, MOTS-c and Epithalon in single-digit mg), so blended vials are less common than separate vials for this combination. Compositions vary widely.

Components in the Longevity Blend
Each peptide in this blend has its own individual calculator page with factual information on vial sizes, reported half-life, and storage. Compositions vary by vendor — the mg ratios above are defaults based on commonly cited formulations.
- NAD+ — A coenzyme central to cellular energy metabolism, redox biology, and NAD+-dependent enzymatic pathways.
- MOTS-c — A 16-amino-acid mitochondrial-derived peptide encoded within mitochondrial DNA, studied for metabolic and AMPK-related signaling.
- Epithalon — A synthetic tetrapeptide analog of the larger polypeptide epithalamin, studied for telomerase-related and circadian signaling mechanisms.
How to use this calculator
The Longevity Blend calculator handles two dose-targeting modes:
- Target total blend dose — "I want 2 mg of the blend per injection." The calculator returns the draw volume and reports how much of each component you're getting at that draw.
- Target specific component — "I want 250 mcg of BPC-157 specifically." The calculator back-calculates the draw from that component's concentration, and reports incidental amounts of the other components delivered at the same draw.
If your vial's stated total mg differs from the sum of component mg values (common on vendor labels — rounding, copper-ion mass, excipients), the calculator flags the mismatch and uses the component sum as the authoritative total for math purposes.
