Enter your vial strength and the bacteriostatic water you're adding. Get the exact concentration, the volume to draw on an insulin syringe, and how many draws each vial yields — instantly.
Your vial
Every batch is HPLC + mass-spec tested by an independent U.S. lab, and the signed COA ships with your order.
Reconstitution is simple arithmetic once you know two numbers: how much peptide is in the vial, and how much bacteriostatic water you add.
Find the total peptide mass printed on the label — e.g. 10 mg. Every Novalabs vial lists it, and the batch ID matches the public COA.
More water gives a more dilute solution and finer measurement; less water means fewer units to draw. 2 mL is a common starting point.
The calculator converts your target amount into insulin-syringe units so you can measure it out precisely, every time.
Common vial-and-water combinations and the concentration each produces. The last column is the insulin-syringe draw for a 250 mcg target.
| Peptide in vial | BAC water | Concentration | Draw for 250 mcg |
|---|---|---|---|
| 5 mg | 2 mL | 2.5 mg/mL | 0.10 mL · 10 u |
| 10 mg | 2 mL | 5 mg/mL | 0.05 mL · 5 u |
| 10 mg | 3 mL | 3.33 mg/mL | 0.075 mL · 7.5 u |
| 15 mg | 3 mL | 5 mg/mL | 0.05 mL · 5 u |
| 20 mg | 2 mL | 10 mg/mL | 0.025 mL · 2.5 u |
U = units on a U-100 insulin syringe (100 units = 1 mL). Reconstitution math for research handling.
Enter the peptide amount in your vial (in mg) and the bacteriostatic water you're adding (in mL). The calculator instantly returns the concentration (mg/mL and mcg/mL), the volume to draw for your target amount, the matching units on a U-100 insulin syringe, and how many draws the vial yields.
There's no single correct amount — the water you add sets the concentration. More water gives a more dilute solution and finer measurement; less water means fewer units to draw for the same amount. 1–3 mL is a common range.
1 mg equals 1,000 mcg, so a 10 mg vial holds 10,000 mcg. The calculator converts automatically — switch your target between mg and mcg with one tap and the draw volume updates.
A U-100 insulin syringe holds 100 units per 1 mL, so 1 unit = 0.01 mL. The calculator converts your target amount into units on that scale, so "draw to 5 units" means 0.05 mL of your reconstituted solution.
No. The amount of peptide in the vial is fixed. Adding more water only changes the concentration — it spreads the same peptide across more liquid, so each unit on the syringe carries proportionally less.
Once in solution, most research peptides are kept refrigerated and protected from light. Follow the storage guidance on your product's Certificate of Analysis and documentation.
