Sustanon is an injectable steroid which contains the hormone testosterone in four different esters equaling a total of 250 mg. Each ML of Sustanon contains:
- Testosterone Propionate - 30 mg
- Testosterone Phenylpropionate - 60 mg
- Testosterone Isocaproate - 60 mg
- Testosterone Decanoate - 100 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 Sustanon, 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 Sustanon provides you immediate kick, so to speak. Isocaproate and Decanoate, meanwhile, are longer-acting esters; these two ensure that the Sustanon 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 Sustanon. Also, you won't need to endure frequent and uncomfortable injections since Sustanon stays active in the blood for a long while. The usual administration with this steroid is every 10 days.
Sustanon is effective if administered 250mg per week or 500mg every 10 days. The feedback with this drug is good; many say that with Sustanon, you need relatively lower dosage but still get impressive results. With other testosterone, you have to take higher dosages, and the dosage requirement climbs up as the body becomes tolerant to the drugs.
And since Sustanon is effective with conservative dosages, you're less likely to experience side effects. Side effects commonly associated with steroid use are mostly dose dependent. Sustanon has potent androgenic and anabolic effects. Thus, this compound is preferred during mass cycles as it drastically increases muscle mass and strength. Plus, with Sustanon you're getting lesser estrogenic side effects and water retention compared with Testosterone Cypionate and Testosterone Enanthate.
Sustanon is particularly beneficial if you're planning to cut up since it can yield 'cleaner' and qualitative muscle mass. Beginners gain qualitative 20 pounds within a couple of months using 250mg/week of Sustanon.
