[Guest guest]

I don't feel you will have a problem you can read about them here in this link.

It is about women becoming men still it's full of good info.

====================================================

Injectable esters commonly used by trans men for testosterone therapy:

Testosterone enanthate: Chemical formula C26H40O3

Testosterone enanthate is one of the main forms of testosterone prescribed to

trans men in the United States. It is a slow-acting ester with a release time

between 8-10 days. The name-brand of T-enanthate available in the United States

is called " Delatestryl, " which is suspended in sesame oil. Testosterone

enanthate is typically injected anywhere between once every week to once every

three weeks. Generic testosterone enanthate can also be obtained through a

compounding pharmacy; such pharmacies can mix the enanthate in either sesame or

cotton seed oil. (For more information about compounding pharmacies, click

here.)

Testosterone cypionate: Chemical formula C27H40O3

Testosterone cypionate is the other main injectable form of testosterone

prescribed to trans men in the United States. It is a slow-acting ester with a

release time between 8-10 days, similar to that of enanthate. The name-brand of

T-cypionate available in the United States is called " Depo-Testosterone, " which

is suspended in cottonseed oil. Testosterone cypionate is typically injected

anywhere between once every week to once every three weeks. Generic testosterone

cypionate can also be obtained through a compounding pharmacy; such pharmacies

can mix the cypionate in either sesame or cotton seed oil. (For more information

about compounding pharmacies, click here.)

Sustanon 100 or 250

" Sustanon " is the brand name for two formulas of injectable testosterone that

contain a blend of esters. " Sustanon 100 " contains three testosterone esters:

testosterone propionate (C22H32O3), testosterone phenylpropionate (C28H36O3),

and testosterone isocaproate (C25H3803). " Sustanon 250 " contains four

testosterone esters: testosterone propionate (C22H32O3), testosterone

phenylpropionate (C28H36O3), testosterone isocaproate (C25H3803), and

testosterone decanoate (C29H4603). Both formulas feature both fast-acting and

slow-acting esters, and can be injected anywhere from once every week to once

every four weeks. Sustanon is prescribed outside of the United States.

Other injectable esters of testosterone:

Testosterone propionate: Chemical formula C22H32O3

Testosterone propionate is a fast-acting ester with a release time of 3-4 days.

To keep blood levels from fluctuating greatly, propionate is usually injected

between one to three times a week. It is for this reason that it is not usually

prescribed for FTM hormone therapy. Some users also report that propionate is a

more painful injection, with swelling and noticeable pain around the injection

site. Brand names of testosterone propionate include " Testovis " and " Virormone. "

Testosterone phenylpropionate: Chemical formula C28H36O3

Testosterone phenylpropionate is a slow-acting ester, with a release time of 1-3

weeks. A popular name brand for T-phenylpropionate is " Testolent. " Testosterone

phenylpropionate is also one of the components of Sustanon and Omnadren.

Omnadren

" Omnadren " is the brand name for a blend of four testosterone esters:

testosterone propionate (C22H32O3), testosterone phenylpropionate (C28H36O3),

testosterone isocaproate (C25H3803), and testosterone decanoate (C29H4603). In

the past, Omnadren consisted of a blend of different esters, but now is

essentially the same formula as Sustanon, mentioned above. It features both

fast-acting and slow-acting esters, and can be injected anywhere from once every

week to once every four weeks. It is sometimes prescribed in parts of Europe.

Aqueous testosterone suspension

In the United States, injectable aqueous (non-esterified) testosterone is

available, but it is very short-acting (it is completely released in the system

within a matter of hours). Therefore, it is not typically used for men in

transition, as it would require constant re-injection to maintain regular blood

levels. The brand name for aqueous testosterone suspension is " Aquaviron. "
