Sustanon
Most testosterones are defined by their name; for example, Testosterone-Enanthate is called so because it is a testosterone with the Enanthate ester attached; pretty simple. However, there is no Sustanon ester, Sustanon refers to a blend of 4 varying ester based testosterones each with a varying half-life mixed together in varying doses. The total mixture, which gives us:
• Testosterone-Propionate
• Testosterone-Phenylpropionate
• Testosterone-Isocaproate
• Testosterone-Decanoate
With this mixture we have two relatively fast esters in Propionate and Phenylpropionate, a moderate size ester in Isocaproate and a very long ester in Decanoate. Once injected testosterone will be released at a fairly even rate regarding milligrams for a month, making this a near perfect HRT medication but for performance purposes this will not do. Because of the short esters attached, to maintain peak testosterone levels Sustanon must at a minimum be injected every three days with every other day administration being far more optimal because of the Propionate ester attached.
Benefits
The benefits of Sustanon are the same as any testosterone be it a single ester or testosterone blend such as Omnadren or Testoviron. All testosterone users of all forms can greatly increase lean muscle tissue as well as increase strength and vitality. Further, as testosterone is a key component in maintaining muscle mass in a calorie restricted diet it is the perfect hormone when we are trying to lean out. Further, because testosterone blocks and reduces muscle wasting hormones that buildup in the body, overall, regardless of the purpose of use we inevitably create a more pleasing physique when testosterone levels increase.
There is however a risk to reward ratio that is in play and it applies to all testosterone; Sustanon makes no exception. The principle is simple; the more you use the greater the benefits will be but the more you use the greater the risk of nasty side-effects. Yes, Sustanon carries the exact same side-effects of all testosterone compounds, the same as Testosterone-Enanthate, Testosterone-Cypionate or any other single ester or mixture you may desire to use. All testosterone use opens the door for an aromatizing effect so estrogenic related side-effects will always be a concern. Issues such as Gynecomastia, high blood pressure, water retention and other estrogenic effects such as decreased sex drive can occur. This is why it is of utmost importance to use a good aromatase inhibitor when supplementing with testosterone; by doing so, coupled with using responsibly we greatly improve our chances of positive and enjoyable use.
