The cypionate ester of Testosterone is none other than the American version of Testosterone Enanthate.
Its effects and properties are identical in all respects to those of the Enanthate (cypionate is shorter than a few hours). Testosterone cypionate is a form of testosterone of delayed effect. Its duration of activity in the body is 2 to 3 weeks, an injection of 250 mg per week is generally sufficient to maintain a high level of Testosterone.
However be aware that in practice the average dose is 500 mg per week. The intake of Testosterone cypionate is suppressive so it is necessary to restart the production of natural testosterone using HCG or Clomid and for the gynecomastia using simultaneously anti-estrogens (Nolvadex and Proviron or arimidex).
