A peptide dosing calculator helps estimate how much solution to draw into a syringe after reconstituting a peptide vial. Because peptides are supplied as lyophilized powder, correct dilution and dose conversion are critical for consistency.
This calculator converts milligrams (mg) into micrograms (mcg) and translates concentrations into IU-based syringe measurements, eliminating manual calculation errors.
How Peptide Reconstitution Works
Reconstitution involves mixing a peptide vial with bacteriostatic water to create a liquid solution. The final concentration depends on:
- Total peptide amount (mg)
- Water volume added (ml)
- Syringe size (IU scale)
Once mixed, injections are measured in IU, not milligrams—making accurate conversion essential.
mcg per IU Explained
Most insulin syringes are calibrated to 100 IU per 1 ml.
This calculator determines:
- mcg per ml
- mcg per IU
- IU required per injection
- ml per dose
These values ensure consistent dosing across injections and days.
Common Peptide Examples
This tool supports typical research-use peptides such as:
- BPC-157
- TB-500
- CJC-1295
- Ipamorelin
Preset values are provided for convenience but remain fully editable.
Example Calculation
A 5 mg vial mixed with 2 ml bacteriostatic water produces:
- 2,500 mcg per ml
- 25 mcg per IU (100 IU syringe)
A 250 mcg dose would require 10 IU per injection.
