Peptide reconstitution calculator.
Enter the peptide amount in the vial and the volume of bacteriostatic water — the calculator shows the resulting concentration in mg/ml and what common draw volumes contain. Presets match the research vials listed by VietPeptide. Research-use arithmetic only, not medical advice.
The formula
- Concentration
- vial mg ÷ water ml = mg/ml
- Example
- 5 mg ÷ 2.5 ml = 2 mg/ml
- Per 0.1 ml
- 0.2 mg (200 mcg)
- Use
- Research solutions only

Research-use arithmetic only. This tool does not provide medical advice, dosage guidance or self-administration instructions. A U-100 insulin syringe marks 100 units per 1 ml, so 1 unit = 0.01 ml — stated here purely as a volume conversion.
How researchers use it.
Lyophilized research peptides ship as dry powder in a vial. To prepare a solution, bacteriostatic water is added, and the concentration depends only on how much water goes in — a 5 mg vial with 2.5 ml gives 2 mg/ml, the same vial with 5 ml gives 1 mg/ml. More water means a more dilute solution that is easier to measure in small, precise volumes.
Every vial listed by VietPeptide states its peptide amount — BPC-157 (5 or 10 mg), TB-500 (10 mg), Retatrutide (15 mg), Tirzepatide (15 mg), Semaglutide (10 mg) — so the presets above match the catalog exactly. Bacteriostatic water 3 ml vials are listed at 100,000 VND and can be added to any Telegram request.
FAQ: reconstitution math.
How does peptide reconstitution math work?
Concentration equals the peptide amount in the vial divided by the volume of bacteriostatic water added. For example, a 5 mg vial reconstituted with 2.5 ml gives 2 mg/ml, so every 0.1 ml of solution contains 0.2 mg (200 mcg). This calculator only does that arithmetic — it is not medical or usage advice.
How much bacteriostatic water should be added to a vial?
There is no single correct volume — it only changes the concentration, not the total peptide amount. More water gives a more dilute solution that is easier to measure precisely; common research choices are 1-3 ml per vial. Enter any volume in the calculator to see the resulting mg/ml.
Where can I get bacteriostatic water in Vietnam?
VietPeptide lists 3 ml bacteriostatic water vials at 100,000 VND reference price, in stock, alongside its research peptide catalog. Availability is confirmed on Telegram @vietpeptide before any payment.
Is this calculator medical advice?
No. It is a concentration calculator for research solutions only. VietPeptide does not provide medical advice, dosage guidance, weight-loss claims or self-administration instructions.
