Susto-Gen 350 is an injectable steroid that includes testosterone bound to four different esters, totaling 350 mg. Each milliliter of Susto-Gen 350 consists of the following:
Testosterone Propionate - 42 mg/ml
Testosterone Phenylpropionate - 84 mg/ml
Testosterone Isocaproate - 84 mg/ml
Testosterone Decanoate - 140 mg/ml
Susto-Gen 350 is a potent anabolic steroid with significant androgenic properties. It is primarily utilized as a bulking agent, leading to impressive increases in strength and muscle size. While it does convert to estrogen—typical of testosterone—this injectable form is recognized for being somewhat more tolerable than Cypionate or Enanthate. As discussed in this book, these occurrences primarily relate to timing. With Susto-Gen 350, testosterone levels rise more gradually, therefore side effects take longer to manifest. However, for comparable levels of hormones in the blood, testosterone will metabolize at the same rate regardless of the ester. Many users may also find it necessary to incorporate an antiestrogen; in those cases, a small dose of Nolvadex (Tamoxifen Citrate) or Proviron (Mesterolone) would be suitable. Additionally, in relation to estrogen, users should expect some water retention with Susto-Gen 350. This can be undesirable for athletes aiming to maintain a refined appearance, which makes this product less suitable for contest prep.
Susto-Gen 350 is formulated to deliver both rapid and prolonged testosterone release. The Propionate and Phenylpropionate esters are rapidly absorbed, entering the bloodstream within the initial four days. The other esters, however, release more slowly, remaining active in the body for around two to three weeks (respectively). This marks a significant advancement compared to standard testosterone forms like Cypionate or Enanthate, which have shorter active durations and less stable blood levels.
