Description: Sustabolic 250 is an oil-based injectable testosterone blend that contains four different testosterone esters: testosterone propionate (30 mg) ; testosterone isocaproate (60 mg) testosterone phenylpropionate (60 mg); and testosterone decanoate (100 mg.) Sustabolic 250 designed to provide a fast yet extended release of testosterone, usually requiring injections once every 3 to 4 weeks in a clinical setting. This is an improvement from standard testosterones such as cypionate or enanthate, which provide a shorter duration of activity. As with all testosterone products, Sustabolic 250 is a very strong anabolic drug with pronounced androgenic activity. It is most commonly used in bulking cycles, providing exceptional gains in strength and muscle mass. AS a benefit of added testosterone propionate, mass building effects will be seen faster than common long ester testosterones like enanthate or cypionate. How Supplied: 250 mg/ml, 10 ml clear glass sterile vials with hot stamping and Flip-off caps with (AKZOPHARMA) printed under transparent colorless plastic. Intramuscular use only. Side Effects (Estrogenic): Testosterone is readily aromatized in the body to estradiol (estrogen). The aromatase (estrogen synthetase) enzyme is responsible for this metabolism of testosterone. Elevated estrogen levels can cause side effects such as increased water retention, body fat gain, and gynecomastia. Testosterone is considered a moderately estrogenic steroid. Administration (Women): This agent is not recommended for women for physique- or performance-enhancing purposes due to strong androgenic nature and tendency to produce virilizing side effects. Side Effects (Androgenic): Testosterone is the primary male androgen, responsible for maintaining secondary male sexual characteristics. Elevated levels of testosterone are likely to produce androgenic side effects including oily skin, acne, and body/facial hair growth. Men with a genetic predisposition for hair loss (androgenetic alopecia) may notice accelerated male pattern balding. Side Effects (Hepatotoxicity): Testosterone does not have hepatotoxic effects; liver toxicity is unlikely. Administration (Men): Although active in the body for a longer time, Sustabolic 250 is usually injected every 7 to 10 days for muscle-building purposes. This schedule will allow for the higher doses most commonly applied by athletes, and more stable elevations in hormone level. The usual dosage among male athletes is in the range of 250-750 mg per injection, taken in cycles 6 to 12 weeks in length. Administration (Women): Sustabolic 250 is not recommended for women for physique- or performance-enhancing purposes due to its strong androgenic nature, tendency to produce virializing side effects, and slow- acting characteristics (making blood levels difficult to control).
