Key product parameters
What is TEST B300?
TEST B300 is a testosterone blend that combines multiple testosterone esters to provide both immediate and sustained release of testosterone. This blend is popular among bodybuilders and athletes for its versatility and effectiveness in promoting muscle growth and strength.

The testosterone blend in TEST B300 includes a mix of short, medium, and long-acting esters. This combination allows for a rapid increase in testosterone levels, followed by a sustained release over time.
