What Is Test Blend 400?
Test Blend 400, also known as Super Test 400, is a high-potency testosterone mix 400 mg solution formulated for intramuscular (IM) injection. Manufactured by G P, this oil-based injectable steroid contains a mix of three testosterone esters, allowing for quick absorption and prolonged effects in the body.
Key Ingredients and Composition
Each Test 400 injection (400 mg/ml) includes:
- 187 mg Testosterone Cypionate – A medium-acting ester that sustains testosterone levels for long periods.
- 188 mg Testosterone Enanthate – A slow-release ester that provides steady and extended effects.
- 25 mg Testosterone Propionate – A fast-acting ester that delivers an initial surge of testosterone.
This combination ensures a balanced release, providing immediate, intermediate, and long-lasting anabolic effects to optimize muscle growth and performance.
