Testosterone suspension is an injectable preparation containing testosterone (no ester) in a water base. Since testosterone is not highly water soluble, the steroid will noticeably separate from the solution when the vial is left to sit. A quick shake will put the drug back into suspension, at least temporarily, so that it can be withdrawn in a consistent dosage. 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. Following common advice, the athlete will commonly inject a full 100mg of testosterone daily, a total of 700 milligrams per week. This is up to 40 times the amount produced by a normal male. Those who have attempted such a cycle are rarely disappointed with the results, as such heavy doses of this hormone will produce nothing less than a dramatic weight gain.

The most popular practice with Testosterone suspension is to inject the drug every day. The dosage will vary greatly depending on the needs of the individual, but is most often in the range of 50mg to 100mg per shot. In most cases the results will be amazing. Although some users will complain about discomfort when injecting water-based steroids, suspension is usually well tolerated.

As would be expected with a strong androgen, suspension can produce a number of unpleasant side effects. As with any testosterone product there will be a high rate of estrogen conversion. Estrogen levels in fact build very quickly with Testosterone suspension, which is probably the worst testosterone to use when wishing to avoid water bloat. Gynecomastia can also develop very quickly during a cycle, and in many cases this drug will be intolerable without additionally taking an anti-estrogen. A combination of Nolvadex and Proviron is an effective way to avoid experiencing such side effects, and is often taken from the onset of a cycle in order to prevent such occurrences before they become a problem. Sensitive individuals may find an investment in the anti-aromatase Arimidex, Femara, or Aromasin to be wiser. These anti-aromatase drugs are much more effective at controlling estrogen. It is also important that the athlete monitor blood pressure and kidney functions closely during a heavy cycle, as water retention becomes more pronounced. Although testosterone puts very little strain on the liver, this drug can be harsh to the kidneys at higher dosages. Of course if the athlete is encountering noticeably high blood pressure or trouble urinating (pain or darkening of the urine), the cycle should probably be discontinued and the doctor paid a visit. Since it converts to DHT. one can therefore expect to endure oily skin, acne, increased aggression and body/facial hair growth during a typical cycle. Propecia/Proscar would be a good idea for those predisposed to male pattern baldness, as suspension is known to aggravate this condition quite easily. Men with an existing hair loss problem may actually prefer to stay far away from this steroid altogether, finding it to be just to strong an item to take risks with. The slower acting oil based injectables like enanthate or cypionate would be a much better place to start with if one still desires to use an injectable testosterone.

Endogenous testosterone production will be quickly and efficiently reduced when using suspension. This can often reach the point of severe testicular shrinkage (atrophy). Some athletes will periodically take HCG while on a cycle, in order to keep this effect to a minimum. Even if no such drug is used during, a combination of HCG and Clornid/Nolvadex should always be used as the cycle is discontinued.

Overall, suspension is an extremely powerful drug, but also one that is prone to causing many side effects. Those looking for only a potent mass agent need not look no further, Suspension will certainly get the job done.
