Sustanon 250 is an injectable oil based testosterone blend.This product contains four different esters, engineered to bring about a quick release of testosterone from the propionate and phenylpropionate esters, combined with a slower release from the decanoate and isocaproate esters. The testosterone blend is made up of; 30mg of testosterone propionate, 60mg of testosterone phenylpropionate, 60mg of testosterone isocaproate and 100mg of testosterone decanoate.
As with any testosterone product, oestrogen related side effects can be expected. Water retention is common with sustanon, and the product is commonly implemented during a bulking cycle when mass building is the goal, and subcutaneous fluids is less of a concern compared to when getting into contest shape. If oestrogen related side effects such as gynecomstia become a concern anti-oestrogen may be implemented, such as nolvadex. An anti-aromatase such as arimidex, femara, or aromasin may be the wiser and more effective option, however.
Injections can be administered in a similar frequency of testosterone enanthate, with biweekly injections in the hope to control blood levels. Injections every 10 days is also another common protocol.
