Frequently asked

How many units is 100 mg of Testosterone Cypionate at 200 mg/mL?

At 200 mg/mL, 100 mg of Testosterone Cypionate is 0.5 mL, which reads 50 units on a 100-unit insulin syringe (each unit holds 2 mg).

How many mL is 50 mg of Testosterone Cypionate?

0.25 mL at 200 mg/mL, or 25 units on a U-100 insulin syringe. At 100 mg/mL the same dose is 0.5 mL, so check the strength printed on your vial.

Do I add bacteriostatic water to Testosterone Cypionate?

No. Testosterone Cypionate comes premixed in oil at the strength printed on the label, so there is nothing to reconstitute. The calculator only needs the strength and the dose.

2x weekly. Same days each week (e.g. Mon/Thu), any time.

How should Testosterone Cypionate be stored?

Store at room temperature, 20-25°C (68-77°F), away from light. Do not refrigerate: cold can make it crystallise. If crystals appear, warming and shaking the vial should dissolve them.
