Question 1

How do I calculate peptide reconstitution?

Accepted Answer

Concentration equals the peptide mass in the vial divided by the bacteriostatic water you add (mg ÷ mL). The volume to draw equals your target dose divided by that concentration, and on a U-100 syringe each unit is 0.01 mL — so units to draw equal the draw volume in mL times 100.

Question 2

How much bacteriostatic water should I add to a peptide vial?

Accepted Answer

There is no single correct volume; it is a trade-off. More water makes each syringe unit easier to measure but dilutes the dose, while less water concentrates it. Common practice is 1–3 mL per vial. Use the calculator's reverse mode to enter a clean target draw and get the exact water volume to add.

Question 3

How many units do I draw on an insulin syringe?

Accepted Answer

On a standard U-100 insulin syringe, 100 units equals 1 mL, so every unit is 0.01 mL. The calculator converts your dose and vial concentration directly into units and marks the draw point on a syringe graphic.

Question 4

How do I know how many doses are in a vial?

Accepted Answer

Divide the total peptide in the vial by your per-injection dose. A 5 mg vial dosed at 250 mcg yields twenty doses. The calculator shows doses per vial alongside the draw so you can plan a cycle.

Question 5

Is this peptide calculator medical advice?

Accepted Answer

No. It is a research-protocol reference reflecting ranges from peer-reviewed and rodent-model literature. It is not medical advice or a prescription, and the compounds are sold for laboratory research use only.
