Testosterone suspension is unique among the steroids derived from the same hormone because it is the only one without any ester components. The less ester a steroid contains, the faster it is absorbed by the bodies and the faster its effects are manifested. Having no ester, testosterone suspension is said to be a “pure” version of testosterone.

Among bodybuilders, Testosterone \suspension\ is known to be an extremely potent mass agent. Most often Testosterone suspension is ranked as the most powerful injectable steroid available, producing an incredibly rapid gain of muscle mass and strength. This is largely due to the very fast action of Testosterone suspension, as the water-based steroid will begin to enter the blood stream almost immediately after an injection is given.

With Testosterone suspension it is just a matter of days. This will usually result in the athlete noticing a size and strength gain by the end of the first week. By the time the athlete is 30 days into a cycle of Testosterone suspension, the length it will usually take for a Sustanon cycle to really begin to work consistently, the mass gains are already (generally) very extreme. Clearly the anabolic effect of Testosterone suspension will be realized much more quickly than we would expect with an oil based (esterified) preparation.
