Testosterone Suspension does not have an ester attached, making it a "pure" version of the parent hormone, Testosterone. Therefore, there is no ester to be accounted for in the weight. This means 100mg of testosterone suspension contains 100mg of the steroid. This makes it the most potent forms of Testosterone available. Gains come quicker and side effects much more possible with such a strong version of this hormone.

Testosterone Suspension is the best-known potential mass builder, yet must be used with caution due its high risk of side effects. Often these effects are the result of the hormone being so readily converted with in the human body to a more androgenic form of itself, Dihydrotestosterone (DHT). Through aromatization, testosterone can also in-turn form estrogen (the female sex hormone). These potential side effects include: water retention, bloating, fat gain, gynecomastia (formation of breast tissue in males) and conversion to DHT (dihydrotestosterone) as well.

Also, supplementing Testosterone will result in the shutting down of the body's natural production of the hormone. The severity of these effects depends mostly on the levels and duration of circulating free testosterone. Testosterone's anabolic/androgenic effects are dependant upon dosage, the higher the dose the higher the muscle building effect. Testosterone promotes aggressive and dominant behavior.

Sensitive individuals may find an investment in the antiaromatase Arimidex to be wiser. While Testosterone suspension is very costly, it is also much more effective at controlling estrogen than the other agents which are currently being used by athletes. If there were ever a time to justify this expense, it would certainly be with a drug like Testosterone suspension. It is also important that the athlete monitor blood pressure and kidney functions closely during a heavy cycle, a trouble area as water retention becomes more pronounced. Although Testosterone puts very little strain on the liver, Testosterone suspension can be harsh to the kidneys as the dosage increases. 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.

Conversion to DHT (dihydrotestosterone) will of course potentate the action of Testosterone in certain tissues. One can therefore expect to endure oily skin, acne, increased aggression and body/facial hair growth during a typical cycle. Propecia - Proscar may be a requirement for those with a familial predisposition for male pattern hair loss, as Testosterone suspension is known to aggravate this condition quite easily. Men with an existing hair loss problem may actually prefer stay far away from Testosterone suspension altogether, finding it to be just to strong an item to take risks with. The slower acting oil based injectables like Propionate and Sustanon would be a much better place to start experimenting then Testosterone suspension if the individual still desires the power of an injectable Testosterone.
