Sustanon 250 is a blend of four testosterone esters testosterone propionate, testosterone phenylpropionate, testosterone isocaproate and testosterone decanoate. These esters make Sustanon one of the longest-lasting steroid compounds available today. It is an ideal compound for putting on size and increasing muscle strength.
Sustanon is also relatively mild on the estrogenic side effects such as gynocomastia and water-retention. Doses of 250 mgs to 1000 mgs per week are recommended to keep a balanced testosterone level, although Sustanon will stay active in the body for up to a whole month.
At higher doses, estrogenic effects can be severe and anti-estrogens like Nolvadex or Proviron are recommended. Taking Sustanon will also reduce the body’s natural production of testosterone so a post-cycle therapy of HCG or Clomid is also desirable.
Sustanon 250 is an oil-based injectable testosterone blend, developed by Organon. It typically contains four different testosterone esters: Testosterone propionate (30 mg); testosterone phenylpropionate (60 mg); testosterone isocaproate (60mg); and testosterone decanoate (100 mg), although a lower dosed version is also produced. An intelligently “engineered” testosterone, Sustanon is designed to provide a fast yet extended release of testosterone. The propionate and phenylpropionate esters in this product are quickly utilized, releasing into circulation within the first four days. The remaining esters are much slower to release, staying active in the body for about two and three weeks (respectively).
