Testosterone suspension becomes active only one hour after it is injected. Suspension increases strength and aggressiveness at a rapid rate and muscle mass gains are relatively quick with its use - superior to other steroids. Testosterone suspension is able to increase glycogen storage in muscle tissue - increases in hardness, vascularity, and overall condition are possible while using testosterone suspension depending on your diet and what your goals are, as well as what drugs suspension is being stacked with. Since suspension is a very potent steroid, it is normally used for bulking purposes.
