Blend calculator
Multi-peptide dosing, one draw.
Blended vials share one volume of water. Enter each component and target dose - we compute the draw that satisfies the limiting component and flag targets that cannot be hit together.

Targets can't be hit exactly in one draw
Every draw from a blended vial carries all components in fixed proportion. To satisfy TB-500, this draw delivers BPC-157 above target. Adjust vial amounts, targets, or use separate vials.Shared draw

The component needing the largest volume sets the draw
| Component | Concentration | Target | In one draw |
|---|---|---|---|
| BPC-157 | 2,500 mcg/ml | 250 mcg | 500 mcg +100% |
| TB-500 | 2,500 mcg/ml | 500 mcg | 500 mcg on target |
In a blended vial every component shares the same liquid, so a single draw contains each component in proportion to its concentration - individual doses can't be adjusted independently.
Blend tips
One liquid, fixed ratios
Everything in a blended vial shares the same water, so every draw contains all components in proportion to their concentrations.
Plan the ratio first
Decide the per-vial amounts so your targets line up at the same draw volume.
The limiting component
The component that needs the largest volume dictates the draw.
Same handling rules
Blends follow ordinary reconstitution practice: water down the glass wall, no shaking, refrigerate after mixing.

Frequently asked questions
How is a blend different from two separate vials?
In separate vials you dose each peptide independently. In a blend both share one liquid, so a single draw always carries them in a fixed ratio.
Why does the calculator warn that my targets are incompatible?
The draw must be large enough to satisfy the component that needs the most volume. Other components may be overshot.
How much water should I add to a blended vial?
Water sets concentration, not the contents. Pick a volume that turns the shared draw into a clean unit number.
