Sustabolic is an oil-based injectable testosterone blend. It typically contains four different testosterone esters: Testosterone propionate (30 mg); testosterone phenylpropionate (60 mg); testosterone isocaproate (60mg); and testosterone decanoate (100 mg). An intelligently "engineered" testosterone, Sustabolic is designed to provide a fast yet extended release of testosterone. The propionate and phenylpropionate esters in this product are quickly utilized, releasing into circulation within the first four days. The remaining esters are much slower to release, staying active in the body for about two and three weeks (respectively). This is a big improvement from standard testosterones such as cypionate or enanthate, which provide a much shorter duration of activity, and a more variable blood level.
As with all testosterone products, Sustabolic is a strong anabolic with pronounced androgenic activity. It is most commonly used as a bulking drug, providing exceptional gains in strength and muscle mass. Although it does convert to estrogen, as is the nature of testosterone, this injectable is noted as being slightly more tolerable than cypionate or enanthate. As stated throughout this book, such observations are only issues of timing however. With Sustabolic, blood levels of testosterone are building more slowly, so side effects do not set in as fast. For equal blood hormone levels however, testosterone will break down equally without regard to ester. Many individuals may likewise find it necessary to use an antiestrogen, in which case a low dosage of Tamoxabolic citrate) or Provirabolic would be appropriate. Also correlating with estrogen, water retention should be noticeable with Sustabolic. This is not desirable when the athlete is looking to maintain a quality look to the physique, so this is certainly not an idea drug for contest preparation.
Being a strong androgen, we can expect the typical side effects. This includes oily skin, acne body/facial hair growth and premature balding. The addition of Propecia® should be able to minimize such side effects, as it will limit the testosterone to DHT (dihydrotestosterone) conversion process. Sustabolic will also suppress natural testosterone production rather quickly. The use of HCG (Human Chorionic Gonadotropin) and/or Tamoxabolic (tamoxifen citrate) may be necessary at the conclusion of a cycle in order to avoid a hormonal crash. Remember though, Sustabolic will remain active in the body for up to a month after your last injection was given. Beginning you ancillary drug therapy immediately after the steroid has been discontinued will not be very effective. Instead, HCG or Tamoxabolic should be delayed two or three weeks, until you are near the point where blood androgen levels are dropping significantly.
Although Sustabolic remains active in the body for approximately three weeks, injections are taken at least every 10 days. An effective dosage ranges from 250mg (one ampule) every 10 days, to 1000mg (four ampules) weekly. Some athletes do use more extreme dosages of this steroid, but this is really not a recommended practice. When the dosage rises above 750-1000mg per week, increased side effects will no doubt be outweighing additional benefits. Basically you will receive a poor return on your investment, which with Sustabolic can be substantial. Instead of taking unnecessarily large amounts, athletes interested in rapid size and strength will usually opt to addition another compound. For this purpose we find that Sustabolic stacks extremely well with the potent orals Oxybolic and Methanabolic. On the other hand, Sustabolic may work better with Trenabolic or Stanabolic if the athlete were seeking to maintain a harder, more defined look to his physique.
