If testosterone is the most powerful mass builder, then gram for gram this is the most powerful testosterone. Suspension is pure testosterone and has no ester attached, and thus no ester calculated in the weight. Where 100 mg of a testosterone ester equals 100 mg minus the weight of the ester, 100 mg of testosterone suspension contains an actual 100 mg of the steroid. Very potent and very powerful. Although it is a rather crude compound, it is without a doubt very, very effective. Suspension is not only not esterified, its not even dissolved in oil the way esters are. Instead it is an aqueous suspension, much like the injectable forms of Winstrol/Stromba (stanazolol). Since a steroid, made of cholesterol, is somewhat lipophillic, it does not readily dissolve in water either. Just as with Winstrol, we will note that the steroid accumulates at the bottom, separated from its water environment if the vial is left Testosterone Suspension sitting for a while. So before use a vial should be shaken, which will provide an even distribution, and then drawn out of the vial. It probably couldn’t hurt to shake the syringe again before injecting as well. Because of its water carrier it does not go directly into the blood, but when it does enter the bloodstream it is released quite quickly delivering very high peak doses. It is injected every day, to every other day at the very least. Some seem to claim that water based steroids will still last in the body for several days on end, but this is not a generally accepted, let alone proven fact. In fact while the steroid probably does exert some action for 2-3 days, most athletes will opt to take advantage of the peak dose and inject it daily. If one sees that even a short ester steroid like propionate is injected every day to every other day in most cases, this logic is easy to follow.
