Reta/AOD Blend Calculator
The Reta/AOD blend is a community term for a combined vial containing Retatrutide and AOD-9604. Compositions vary significantly by vendor since there is no standard ratio — Retatrutide is dosed in mg while AOD-9604 is dosed in mcg, so even the default values below are a starting point, not a standard.

For vials containing 2+ peptides in one lyophilized powder. Enter each component's mg — the calculator handles the proportional math.

Components in the Reta/AOD 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.
- Retatrutide — A triple agonist of the GLP-1, GIP, and glucagon receptors, investigated in clinical trials as a multi-receptor incretin analog.
- AOD-9604 — A synthetic fragment corresponding to the C-terminal 176-191 residues of human growth hormone, studied for lipolytic signaling.
How to use this calculator
The Reta/AOD 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.
