Sustanon-250 is an oil-based injectable testosterone blend that contains four different testosterone esters: testosterone propionate (30 mg); testosterone phenylpropionate (60 mg); testosterone isocaproate (60mg); and testosterone decanoate (100 mg. ) Sustanon is 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, Sustanon-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. Sustanon 250 contains a mixture of four testosterone compounds, which have been modified with the addition of carboxylic acid esters (propionic, propionic phenyl ester, isocaproic, and decanoic acids) at the 17-beta hydroxyl group. Esterified forms of testosterone are less polar than free testosterone and are absorbed more slowly from the site of injection. Once in the bloodstream, the ester is removed to yield free (active) testosterone. Esterified forms of testosterone are designed to prolong the window of therapeutic effect following administration, allowing for a less frequent injection schedule compared to injections of free (unesterified) steroid. Sustanon 250 is designed to provide a rapid peak in testosterone levels (24-48 hours after injection) and maintain physiological concentrations for approximately 21 days/34 Each 250 mg ampule provides 176mg of testosterone.

Testosterone is readily aromatized in the body to Estradiol (Estrogen). Elevated levels of Estrogen can cause side effects such as increased water retention, body fat gain, and gynecomastia. 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. Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis.
Although active in the body for a longer time, Sustanon 250 is usually injected every 7 to 10 days for muscle-building purposes. Usual dosage among male athletes is in the range of 250-750 mg per injection, taken in cycles of 6 to 12 weeks in duration. These levels are enough for most users to notice exceptional gains in muscle size and strength.
