Acetate: the shortest acting is the acetate (ex. trenbolone acetate). Acetate esters of any steroid delay the release of that drug for somwere from 24 to 48 hours at most. This ester is also found in oral Primobolan (methenolone acetate, 5-mg tablets) and rarely, it's found coupled to Testosterone.

Propionate: Propionate esters will slow the release of a steroid for 48 to 72 hours or so. To keep plasma levels constant, propionate compounds are usually injected three times weekly. Testosterone propionate is the most popular propionate steroid.

Phenylpropionate: Phenylpropionate will extend the release of active steroid a few days longer than propionate, somewhere around 72 to 96 hours. To keep plasma levels constant, injections are given at least twice weekly. Durabolin is the drug most commonly seen with a phenylpropionate ester (nandrolone phenylpropionate) although it's also used with Testosterone in Sustanon

Enanthate: Enanthate is one of the most popular esters used in steroid manufacturing (most commonly seen with Testosterone but is also used in other compounds like Primobolan Depot). Enanthate will release a steady level of steroid for approximately 10 to 14 days. Although in medicine, enanthate compounds are often injected on a bi-weekly or monthly basis, most bodybuilders will inject at least weekly to help maintain a steady blood level.

Cypionate: Its release duration is just about identical to that of enanthate (10 to 14 days) and the two are likewise thought to be interchangeable in male hormone replacement therapy.many people think that cypionate is more powerful than enanthate, although in reality there's little difference between the two.

Decanoate: This is most commonly used with the hormone nandrolone (as in Deca-Durabolin) and is found in all corners of the world. Testosterone decanoate is also the longest acting ester found in Sustanon, significantly increasing it's duration of action. The release time with Decanoate compounds is listed to be as long as 30 days, although in reality most athletes find that plasma levels of steroid seem to drop quite a bit after two weeks. To keep blood levels more steady, athletes usually do weekly injections.

Undecylenate: This ester is very similar to decanoate. Its release is very similar (approximately two to three weeks), perhaps extending a day more than decanoate. The undecylenate ester seems to be only found in the veterinary preparation Equipoise (boldenone undecylenate)
