Sustanon 250

What is it?

Sustanon 250 is a blend of four estered testosterones: 100 mg of testosterone decanoate, 60 mg of testosterone phenylpropionate, 60 mg of testosterone isocaproate and 30 mg of testosterone propionate. The drug was developed by Organon, the idea behind it was to balance the action of each testosterone-type and mix long-acting, short-acting and medium-acting esters. Many bodybuilders initially embraced the medicament but later found out that the levels of testosterone released in blood sharply decrease during the week. This results in high testosterone-levels during the first two days after injecting Sustanon 250 and very low testosterone-levels during the last two days (provided one injects once a week). Sustanon 250 is clearly not a steroid of choice for bodybuilders.

What are its effects?

The effects of Sustanon 250 are the same as the effects of testosterone esters it contains. Testosterone has strong anabolic and androgenic effects.

What are its side-effects?

The side-effects of Sustanon 250 are the same as the side effects of the four testosterone esters it contains. The medicament is not liver-toxic, but testosterone has obviously very strong side-effects resulting from its androgenic and estrogenic (as it readily aromatizes) effects. Suppression of natural testosterone production is strong and supportive medication is necessary.

How is it administered?

A weekly dose of up to 1000 mg is usually administered by those using Sustanon 250 for bodybuilding. Novaldex, HCG or other supportive medication is necessary.
