Sustanon

Quick info about Sustanon

This product was developed by Organon as an ideal HRT (Hormone Replacement Therapy) solution, and it was thought at the time that the different esters would be able to provide a constant release of Testosterone over several months time. Sustanon is a blend of different estered testosterones (4 of them): testosterone propionate - 30 mg, testosterone phenylpropionate - 60 mg, testosterone isocaproate - 60mg, and testosterone decanoate -100 mg.

For athletes or bodybuilders (who routinely use between half a gram and a gram of testosterone per week), this product is really no better than any other form of injectable testosterone.

Testosterone will cause both muscle growth as well as fat loss. It sends a message to muscle cells to store more contractile protein (called actin and myosin), thus making your muscles grow.

Since Sustanon is simply a form of (well actually 4 forms of) testosterone, we also know that administration of this compound will produce a dose respondent curve. A what? Yeah, basically, a "dose respondent curve" is the fancy way of saying "the more you take, the bigger you get." This is true of Sustanon as well as for every form of testosterone, up to a point.

Unfortunately, Sustanon will also do all of the bad things that any form of testosterone is known for: It will convert to the female hormone estrogen (via a mechanism known as aromatization) by the (you guessed it) aromatize enzyme. Excessive estrogen can lead to unwanted side effects, such as acne, the growth of breast tissue (gynecomastia), fat gain and reduced fat breakdown, loss of sex drive, testicular shrinkage and water retention.
