Sustanon 250  by LA Pharma

Testosterone Compound (sustanon) is an oil-based injectable containing four different testosterone esters: testosterone propionate (30 mg); testosterone phenylpropionate (60 mg); testosterone isocaproate (60mg); and testosterone decanoate (100 mg). It is an intelligently "engineered" blend 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 approximately two and three weeks (respectively). This is an improvement from standard testosterones such as cypionate or enanthate, which provide a much shorter duration of activity, and a more variable blood level.

This is one of the most popular injectable testosterones because the combination of the four different esters work synergistically together, both fast acting and long lasting. The blend of testosterones allows it to be recognized by the receptors for longer periods of time than other testosterones. The use of HCG (Human Chorionic Gonadotropin) and/or Clomiphene Citrate/Tamoxifen Citrate may also be beneficial at the conclusion of use in order to ensure balance in the hormone system.

Although it remains active in the body for approximately two to three weeks, injections are typically taken at least every 10 days. An effective dosage for most ranges from 250mg - 500mg every 7 to 10 days. 

LA Pharma  offers this  product in a 10ml vial, 250mg/ml = 2500mgs.
