Testosterone propionate is a commonly manufactured, oil-based injectable testosterone compound. The propionate ester will slow the rate in which the steroid is released from the injection site, but only for a few days. Testosterone propionate is therefore much faster acting than other testosterone esters such as cypionate or enanthate, and requires a much more frequent dosing schedule, in order to maintain stable blood levels. While cypionate and enanthate are injected on a weekly or bi-weekly basis, propionate is usually injected every second. The propionate ester can be very irritating to the site of injection. In fact, many sensitive individuals choose to stay away from this steroid completely, their body reacting with a pronounced soreness and low-grade fever that may last for a few days.
Sustanon 250 is not recommended to those allergic to testosterone propionate, testosterone phenylpropionate, testosterone isocaproate, testosterone decanoate, or any of the ingredients of Sustanon 250. It is also not recommended to those allergic to peanuts or soya or those diagnosed with breast or prostate cancer. Sustanon is also not recommended to children under 3 years of age and pregnant or breastfeeding women. This potent steroid should be used with a high sense of care and diligence by individuals diagnosed with health conditions such as high blood pressure, epilepsy, migraine, kidney or heart or liver diseases, cancer of the bone, and sleep apnea. Medical advice is of great importance if Sustanon is taken by the elderly or an individual with cancer and a history of endometrial cancer. Extra medical supervision is also recommended for treating young boys as males hormones could lead to early sexual development and delayed growth.
As a non-aromatizing androgen, dihydrotestosterone is extremely potent. Aromatization refers to the conversion of testosterone or anabolic steroids into estrogen. High estrogenic activity causes bloating, acne, water retention and oily skin. As dihydrotestosterone does not aromatize even at high dosages, users do not face the aforementioned side-effects. Lack of water retention also has a hardening effect on muscle tissue, in bodybuilders. Being a powerful androgen, dihydrotestosterone is also responsible for a shift in the estrogen-testosterone ratio in the body. Due to its predominant androgenic component, the steroid has a stimulating effect on the adreno-pituitary functions, and causes neurological excitation in the ‘sexual orientation areas of the brain’. This in turn, spikes sex drive in males.
