PHARMATEST U 250 (testosterone undecanoate) is a long-acting testosterone ester with a half-life of approximately 20 to 30 days. Due to its long half-life, testosterone undecanoate (TU) can be conveniently used in hormone replacement therapy (HRT). The frequency of testosterone injections can be reduced to once every 2 to 3 months when using TU in HRT! Bodybuilders and other athletes can use TU as a base for very long (“perpetual”) cycles, allowing for a reduction in injection frequency while maintaining a stable hormonal balance. In a “perpetual” cycle, the frequency of injections can be every 2 to 6 weeks. A single administration of 1000 mg of TU will create a three-month testosterone baseline at physiologically normal levels. Similarly, a dosage of 1500 to 2500 mg of TU per month is suitable for a perpetual cycle.
With a half-life of about 3 weeks, it is a very slow-release ester, significantly slower even than PHARMATEST C 250 (testosterone cypionate).
Chemical name (17β)-17-Hydroxoandrost-4-en-3-on
Formula C19H28O2
Anabolic activity index 100% (reference drug)
