Testagen dosage chart
20 mg Vial
Testagen is dosed at 100 mcg–300 mcg daily via subcutaneous injection in educational protocols. A 20 mg vial reconstituted with bacteriostatic water yields about 6.67 mg/mL. This information is for research and educational use only.
- Reconstitute
- Add 3.0 mL bacteriostatic water → ~6.67 mg/mL concentration.
- Typical daily range
- 100–300 mcg once daily (gradual titration).
- Easy measuring
- At 6.67 mg/mL, 1 unit = 0.01 mL ≈ 66.7 mcg on a U‑100 insulin syringe.
- Storage
- Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles.
Testagen dosage FAQs
How much bacteriostatic water do you use to reconstitute Testagen?
Add 3.0 mL bacteriostatic water → ~6.67 mg/mL concentration. for a 20 mg Vial vial. Add the water slowly against the inside wall of the vial and swirl — never shake — until the powder fully dissolves.
How should reconstituted Testagen be stored?
Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles..
How many insulin syringe units equal a Testagen dose?
Units depend on the water volume you used. Divide your target dose by the vial concentration to get millilitres, then multiply by 100 — 1 unit on a U-100 insulin syringe is 0.01 mL. The Spartan Peptides reconstitution calculator does this conversion for you.
Is Testagen approved for human use?
No. Testagen is sold and referenced strictly as a research chemical. Nothing on this page is medical advice and the material is not for human consumption.
Educational and research information only. Not medical advice, not for human consumption. Values are reference figures — always verify your own math with the reconstitution calculator.
On any insulin syringe, 1 unit = 0.01 mL, so unit counts above hold across brands.
