Test 400

Test 400 is a high-dose testosterone blend that combines several testosterone esters into one injection, giving a total of 400mg per ml. It is used as a single base injection to drive muscle growth and strength, combining fast and slow esters so levels rise quickly and hold steadily.

As a general guide and not medical advice, users commonly inject 400mg once or twice per week, though the high concentration makes it better suited to experienced users because higher-dose oils can cause more post-injection soreness. Always confirm dosing with a healthcare professional.

The most commonly reported effects are oestrogen-related sides such as water retention and gynaecomastia, acne, raised blood pressure and a higher red blood cell count. Post-injection soreness is also more common with high-concentration blends. An aromatase inhibitor and regular bloodwork are commonly used.

Yes. It is still testosterone, so natural production is suppressed and a full post cycle therapy based on Nolvadex or Clomid is required after the cycle. This is general information, not a prescription.
