PHARMATEST U 250 (testosterone undecanoate)

PHARMATEST U 250 contains testosterone undecanoate, an ultra-long ester known for its extended release profile. With an exceptionally long activity window, this formulation is widely associated with long-term testosterone maintenance protocols where stable hormone levels are the priority. Because it remains active for weeks, injection schedules can be spaced far apart compared to shorter esters.

This extended release makes it suitable for prolonged regimens that aim to maintain consistent testosterone levels with minimal fluctuations. In performance settings, it is often chosen for long-duration cycles where fewer injections are preferred while preserving a steady hormonal environment. Compared to faster esters such as testosterone cypionate, testosterone undecanoate releases much more gradually, offering smoother and longer-lasting effects.
