Peptide Blend Calculator
One draw, every component — see what each delivers. Research use only. Updated 16 July 2026.
A blend is several peptides in one vial at a fixed ratio, so a single draw delivers all of them at once — you cannot dose one alone. Pick a blend, set the water and the amount you draw, and see the dose of each component and how many draws the vial holds.
Componentmg in vial
| Component | In vial | Concentration | Per draw |
|---|---|---|---|
| GHK-Cu | 50 mg | 16.67 mg/mL | 3333 mcg |
| TB-500 | 10 mg | 3.33 mg/mL | 667 mcg |
| BPC-157 | 10 mg | 3.33 mg/mL | 667 mcg |

One draw = all components
Because the components share a vial at a fixed ratio, the syringe volume you draw sets the dose of every one of them at the same time. To raise or lower one, you move them all — the only way to change the ratio is a different blend or separate vials.
How to use it
- Set the total BAC water for the whole vial, not per component — they share the same solution.
- The draw (in insulin units) is what you pull into the syringe; it fixes every component dose at once.
- Presets use the documented blend ratios; edit any mg to match your own vial or a custom mix.
