About Testosterone 400
Testosterone 400 (T400) is a high-concentration testosterone blend delivering 400 mg of active hormone per millilitre, typically combining Testosterone Enanthate, Cypionate and Decanoate/Propionate in a single carrier oil. Its core advantage is reduced injection volume: a 400–800 mg weekly dose takes just 1–2 ml of oil instead of 2–3.5 ml of standard 250 mg/ml testosterone.
By combining multiple testosterone esters with distinct oil-solubility thresholds, 400 mg/ml stays in solution without crashing. Once injected intramuscularly, the medium and long esters release steadily over 7–14 days, making it ideal for multi-compound stacks where total syringe volume would otherwise be high.
- 400 mg/ml delivers 60% more active testosterone per ml than standard 250 mg/ml
- Ideal when co-drawing Testosterone with Deca Durabolin, Boldenone or Masteron in one syringe
- Lower cost per milligram of testosterone across 12–16 week mass cycles
- HPLC-verified concentration with published batch laboratory certificate
