Beta · in development
An experimental calculator with extra modes we're still testing — features may change and this version isn't part of the offline app. For the stable, offline-installable tool, use the reconstitution calculator.
Peptide Calculator Beta
The reconstitution calculator plus experimental modes — a reverse solver (water for a target draw), an IU mode for HGH & GH, quick unit converters, and shareable links. Inputs and results update in real time.
Inputs
Enter the water you plan to add — get your draw volume and concentration.
Edit either this OR the concentration below — they're linked.
Auto-calculated from water volume; type to override.

mL · 10 units
Add 2 mL BAC water to a 5 mg vial → 250 mcg/0.1 mL. Draw 10 units (0.1 mL) for a 250 mcg dose.
U-100 Insulin Syringe
10 units · 0.1 mLEach tick = 1 unit (0.01 mL). Major labeled marks every 10 units (0.1 mL).
Quick Converters
HGH ≈ 3 IU per mg
Quick Reference
Concentration in mcg per 0.1 mL by vial size and water volume. Your current selection is highlighted.
| Vial \ Water | 1 mL | 2 mL | 3 mL | 5 mL |
|---|---|---|---|---|
| 2 mg | 200 | 100 | 66.7 | 40 |
| 5 mg | 500 | 250 | 166.7 | 100 |
| 10 mg | 1000 | 500 | 333.3 | 200 |
How to Reconstitute Peptides
- 1Clean the vial stopper with an alcohol swab.
- 2Draw the calculated amount of bacteriostatic water into a syringe.
- 3Inject water slowly into the vial, aiming the stream against the glass wall — never directly onto the peptide powder.
- 4Gently swirl the vial — do not shake.
- 5Allow to dissolve completely (may take 1–5 minutes).
- 6Store reconstituted peptide refrigerated at 2–8°C.
- 7Note the date of reconstitution — most reconstituted peptides are stable for 4–6 weeks refrigerated.
Storage Guidelines
- Unreconstituted: room temperature or refrigerated, away from light.
- Reconstituted: refrigerated at 2–8°C, use within 4–6 weeks.
- Never freeze reconstituted peptides.
