Reconstitution without guesswork
Enter the vial amount, the water added, and the target amount. The calculator turns concentration into mL, syringe units, and doses per vial.

Blend mode lets you enter multiple compounds in one vial and checks whether your target doses actually line up in a single draw.

Quick Dose Reference
Common doses at your current concentration
| Dose | Syringe Units | Volume (ml) |
|---|---|---|
| 100 mcg | 4.0 | 0.040 |
| 200 mcg | 8.0 | 0.080 |
| 250 mcg← Your dose | 10.0 | 0.100 |
| 500 mcg | 20.0 | 0.200 |

Reconstitution Tips
Adding Water
Inject bac water slowly along the vial wall. Don't spray directly onto the powder. Swirl gently, never shake.
Storage
Reconstituted peptides go in the fridge (2-8°C / 36-46°F), away from direct light. Do not freeze after reconstitution.
Blend Reality Check
A blend only works cleanly if your target doses preserve the vial ratio. If the calculator shows different unit counts per compound, the blend math is off.
Measuring Accuracy
Pull the plunger slowly. Read at eye level. The flat bottom of the meniscus is your measurement point.
Sanity check
The calculator is math. Before you trust the result, make sure the vial amount, water added, dose unit, and syringe size match what is actually in front of you.
