Biotech Sustanon 300 is a powerful testosterone blend combining four testosterone esters to provide both fast-acting and long-lasting anabolic effects. Each ml delivers a total of 300mg of testosterone, making it one of the more potent blends on the market. Supplied in a 10ml multi-dose vial, this product is ideal for serious athletes, bodybuilders, and TRT users looking for stable hormone levels, consistent performance, and massive gains.

Produced by Biotech Labs, Sustanon 300 is a pharmaceutical-grade injectable steroid designed to optimize both the onset and duration of testosterone release in the body. Its composition ensures quick hormonal spikes for immediate benefits while maintaining long-term stability for sustained progress.


🔬 What is Sustanon 300?

Sustanon is a multi-ester testosterone blend originally developed for testosterone replacement therapy (TRT), but widely adopted in bodybuilding due to its balanced release profile. Biotech’s Sustanon 300 includes the following esters:

  • Testosterone Propionate – 30mg

  • Testosterone Phenylpropionate – 60mg

  • Testosterone Isocaproate – 60mg

  • Testosterone Decanoate – 150mg

This precise formulation mimics the body’s natural testosterone production rhythm and offers the convenience of less frequent injections while maintaining steady hormone levels.
