PHARMATEST U 250 AMPULES

PHARMATEST U 250 features testosterone undecanoate, one of the longest-acting testosterone esters available. Thanks to its extended release profile, this compound is commonly chosen when long injection intervals and stable hormone levels are the priority. Its slow metabolism allows testosterone levels to remain steady for weeks rather than days.

Because of this prolonged activity, testosterone undecanoate is often associated with hormone replacement protocols that require minimal injection frequency. In performance-focused use, it is frequently selected as the backbone of extended or so-called long-term cycles, where consistency matters more than rapid peaks.

A single high-dose administration can maintain testosterone levels within a normal physiological range for several months, while ongoing monthly use supports long-duration cycles with fewer injections. With an effective half-life of roughly three weeks, PHARMATEST U 250 releases significantly slower than shorter esters such as testosterone cypionate.
