Reconstitution Calculator
Calculate how much bacteriostatic water to add, how many syringe units to draw, and how many doses you'll get per vial. Select a preset or enter custom values.
Blend mode lets you enter multiple compounds in one vial and checks whether your target doses actually line up in a single draw.
Check the label on your vial

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 |
| 1,000 mcg | 40.0 | 0.400 |
| 2,000 mcg | 80.0 | 0.800 |
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). Most are stable for 4-6 weeks. Never 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.
