Pharmaceutical name: Testosterone
Testosterone suspension is an injectable preparation containing testosterone (no ester) in a water base. Although it may contain testosterone without the benefit of an ester, and contrary to popular belief, the microcrystal design of this injectable will sustain an elevated testosterone release for 2-3 days. Clearly the suspension we see today is not the basic water plus testosterone design used in the 1940"s. And since the drug will not leave circulation in a matter of hours, it is obviously useful. Among bodybuilders, "suspension" is known to be an extremely potent mass agent. It is often ranked as the most powerful injectable steroid available, resulting in an incredibly rapid gain of muscle mass and strength. This is largely due to the very fast action of this drug, as the water-based steroid will begin to enter the blood stream almost immediately after an injection is given. Unlike longer esters such as enanthate or cypionate which take weeks for blood levels to reach maximiun theraputic levels, with suspension it is just a matter of days. Clearly the anabolic effect of this testosterone will be realized much more quickly than we would expect with an oil based (esterified) preparation. It is also important to remember that 100mg of a testosterone ester is not equivalent to 100mg testosterone of pure testosterone (as in suspension). When an ester is present, its weight is obviously included in the preparation"s milligram total. Looking at Testosterone enanthate, 100mg of this compound equates to only 72mg of raw testosterone. So the bodybuilder who uses 400mg of enanthate weekly is really getting about 288mg of testosterone into his body each week. This is clearly a great increase over the endogenous testosterone level of the average male, which is in the range of 2.5 to 11 mg per day. But the general point is that during a cycle of Testosterone suspension we will often see a much more dramatic intake of testosterone on average than is typically utilized with oils.
Each 10ml Vial contains 100mg/ml testosterone
