Description

Description:
Sustanon® 250 is an oil-based injectable testosterone blend that contains four different testosterone esters: testosterone propionate (30mg); testosterone phenylpropionate (60mg); testosterone isocaproate (60mg); and testosterone decanoate (100mg). 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. A shorter-acting version of Sustanon®, called Sustanon® 100, is also made in certain areas (see: Sustanon 100).

Administration (Men):
To treat androgen insufficiency, the prescribing guidelines for Sustanon® 250 call for a dosage of 250mg every 3 weeks. Although active in the body for a longer time, Sustanon® 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 amongst male athletes is in the range of 250-750mg per injection, taken in cycles 6 to 12 weeks in length. This level is sufficient for most users to notice exceptional gains in muscle size and strength.

Sustanon® 250 is usually incorporated into bulking phases of training, when added water retention will be of little consequence, the user more concerned with raw mass than definition. Some do incorporate this drug into cutting cycles as well, but typically in lower doses (125-250mg every 7-10 days) and/or when accompanied by an aromatase inhibitor to keep estrogen levels under control. Sustanon® 250 is a very effective anabolic drug and is often used alone with great benefit. Some, however, find a need to stack it with other anabolic/androgenic steroids for a stronger effect, in which case an additional 200-400mg per week of boldenone undecylenate, methenolone enanthate, or nandrolone decanoate should provide substantial results with no significant hepatotoxicity. Testosterone is ultimately very versatile and can be combined with many other anabolic/androgenic steroids to tailor the desired effect.

Some bodybuilders have been known to use excessively high dosages of this drug (1,000mg per week or more), although this practice is generally not advised. At dosages above 750mg per week, water retention will likely account for more of the additional weight gainthan new muscle tissue. The practice of “megadosing” is inefficient (not to mention potentially dangerous), especially when we take into account the typical high cost of Sustanon 250. Such use is usually not justified outside of aggressive bodybuilding regimens.

Administration (Women):
Sustanon® 250 is rarely used with women in clinical medicine. When applied, it is most often used to induce masculinization in female to male transsexuals. Sustanon® 250 is not recommended for women for physique- or performance-enhancing purposes due to its strong androgenic nature, tendency to produce virilizing side effects, and slow- acting characteristics (making blood levels difficult to control).
