Most common combinations — add 2ml BAC water to your vial and draw the units shown for your target dose.
Units to draw (2ml BAC water)
On a standard U-100 insulin syringe · 1 unit = 0.01ml
| Vial size | 250mcg | 500mcg | 1mg | 2mg |

| 10mg | 5 IU | 10 IU | 20 IU | 40 IU |
| 20mg | 2.5 IU | 5 IU | 10 IU | 20 IU |
| 30mg | 1.7 IU | 3.3 IU | 6.7 IU | 13.3 IU |
| 40mg | 1.25 IU | 2.5 IU | 5 IU | 10 IU |

How It Works
Four steps to a precise dose
1
Reconstitute your vial
Add bacteriostatic water slowly to your lyophilised peptide. 2ml is standard for most 10mg vials and gives clean, easy-to-measure syringe marks.
2
Find your volume
Enter your vial size in mg, how much BAC water you added, and your target dose. The calculator does the maths instantly.
3
Draw using an insulin syringe
Standard U-100 insulin syringes are 1ml / 100 units. Every unit equals 0.01ml. Draw to exactly the unit mark shown in the result.
4
Store correctly
Refrigerate reconstituted peptides at 2–8°C. Use within 28 days. Keep the remaining lyophilised vial sealed and refrigerated until needed.

FAQs
Common questions
2ml is the standard for most research peptide vials — it produces easy-to-measure syringe marks for the most common doses. Use 1ml if you need a more concentrated solution, or 3ml if you prefer more dilute. Adjust the calculator to match whatever you use.
A standard U-100 insulin syringe (1ml, 100 units) is correct. Each unit on the syringe equals 0.01ml. They're widely available at pharmacies. This calculator is calibrated for U-100 syringes.
1mg = 1,000mcg. The calculator accepts both — enter either one and the other updates automatically.
Store at 2–8°C and use within 28 days. Do not refreeze. Keep unused lyophilised vials sealed and refrigerated — they remain stable for up to 24 months.
Yes — it works for every lyophilised research peptide: Tirzepatide, Retatrutide, Semaglutide, BPC-157, TB-500, GHK-Cu, CJC-1295, MOTS-C, SS-31, NAD+ and any other compound with a known vial size.
