| Sustanon 250 is an oil-based injectable Testosterone blend. Sustanon developed by
the international drug firm Organon. Sustanon 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 are
quickly utilized, releasing into circulation within the first four days.
The remaining esters are much slower to release. Sustanon stayes active
in the body for about two and three weeks (respectively). This is a big
improvement of Sustanon from standard Testosterones such as cypionate or
enanthate, which provide a much shorter duration of activity, and a more
variable blood level. As with all Testosterone products, Sustanon is a
strong anabolic with pronounced androgenic activity. Sustanon is most commonly
used as a bulking drug, providing exceptional gains in strength and muscle
mass. Although it does convert to estrogen, as is the nature of Testosterone,
Sustanon injectable is noted as being slightly more tolerable than cypionate
or enanthate. |
