BioSus 250 is an injectable steroid which contains the hormone testosterone in four different esters equaling a total of 250 mg. The rate at which the hormones are released depends on the weight and length of the esters; some may take days, while some may take weeks. The longer and the heavier the ester attached, the longer the active life of the steroid. In the case of BioSus, the Propionate and the Phenylpropionate esters have relatively shorter active lives.
Propionate has only one to two days of active life while Phenylpropionate has four to five days. Because of these two esters BioSus provides you immediate kick, so to speak. Isocaproate and Decanoate, meanwhile, are longer-acting esters; these two ensure that the BioSus continues to exert tissue building active for a long time, oftentimes lasting for a month. Isocaproate and Decanoate has active life of two and three weeks, respectively. These characteristics guarantee that you're going to get immediate and sustained anabolic activity from BioSus. Also, you won't need to endure frequent and uncomfortable injections since BioSus stays active in the blood for a long while. The usual administration with this steroid is every 10 days.
