What is TEST 400?

TEST 400 is a high-concentration testosterone blend that packs 400mg of testosterone per millilitre. It combines multiple testosterone esters to give you both fast-acting and long-lasting effects in a single injection. It was designed for experienced users who want serious results without pinning every day.

Quick Facts

How Does It Work?

TEST 400 delivers testosterone directly into the bloodstream via the muscle. Testosterone binds to androgen receptors in muscle tissue, signalling the body to build more protein and retain more nitrogen. The blend of esters means levels rise quickly and stay elevated for an extended period.

What It's Used For

• Bulking — rapid gains in muscle size and bodyweight
• Strength cycles — significant increases in raw power output
• Base compound — used as a testosterone foundation in most stacks

What to Expect

Most users notice increased strength and fuller muscles within the first two weeks. By weeks four to six, noticeable size gains and improved recovery are typical. Water retention can occur at higher doses, so diet and aromatase inhibitor use are important.

Possible Side Effects

• Water retention and bloating, especially at higher doses
• Increased oestrogen levels leading to gynecomastia if unmanaged
• Natural testosterone suppression requiring post-cycle therapy

Cycle & Dosage Notes

A standard cycle runs 10–14 weeks, with injections split across two days per week to keep blood levels stable. An aromatase inhibitor such as Anastrozole should be run alongside to control oestrogen. PCT with Nolvadex or Clomid should begin approximately two weeks after the last injection.

Storage

Keep at room temperature (15–25°C), away from light and moisture. Leave in the original packaging.
