TestoGen 250 is a form of testosterone that has been modified by attaching a carboxylic acid ester to the 17-beta-hydroxyl group. This has the effect of slowing down the release of testosterone into the bloodstream by maintaining it for about 2 weeks.
TestoGen is mainly integrated in bodybuilding bulking times when the addition of raw muscle mass and a large increase in strength is the goal. It can be used alone or stacked with other anabolic / androgenic steroids to increase its effects. In addition, it is also effective in cutting cycles when muscle retention is desired.
It is still the most prescribed form of testosterone in a clinical setting and is used to treat low libido, muscle waste, declining energy levels. It is the main component of testosterone replacement therapy (TRT).
