Pharma TEST U250 (Testosterone Undecanoate) is an exceptionally long-acting testosterone ester, with a half-life of approximately 30-36 days. Its extended half-life makes it effective for hormone replacement therapy (HRT). When using TU, testosterone injections can be minimized to once every 2-3 months. In bodybuilding, TU serves as the foundation for prolonged ("eternal") cycles, enabling less frequent injections while maintaining a stable hormonal level. During an "eternal" cycle, injections may be given every 2-6 weeks, and for HRT, every 2-3 months.
Administering a single dose of 750mg TU can provide a consistent physiological level for about three months. For an eternal cycle, a monthly dosage of 1500-2500 mg TU is recommended. In the context of HRT, a dosage of 1000mg TU is advised every 2-3 months.
With its half-life of around 30-36 days, TU is a slower-release ester compared to PHARMATEST C 250 (Testosterone Cypionate).
