Deca-Test 400

Deca-Test 400 is a high-dose blend that combines testosterone with nandrolone decanoate in a 400mg per ml oil. It is aimed at experienced users who want steady mass and joint comfort from a single injection during a bulking phase.

As a general guide and not medical advice, users commonly inject 1ml once or twice per week for a bulking cycle of 10 to 12 weeks. The high concentration and mix of compounds make it an experienced-only blend. Always confirm dosing with a healthcare professional.

The most commonly reported effects are water retention, a rise in prolactin and oestrogen-related sides, raised blood pressure and a higher red blood cell count, with possible post-injection soreness from the high concentration. Cabergoline, an aromatase inhibitor and regular bloodwork are sensible precautions.

Yes. The blend suppresses natural testosterone production, so a full post cycle therapy is required, and cabergoline plus an aromatase inhibitor are commonly kept on hand. This is general information, not a prescription.
