Applications:

Testosterone is both anabolic and androgenic in nature. Users of this steroid will notice a dramatic gain in muscle size and strength, as well as an overall sense of well being and increases libido and sex drive.

Testosterone aromatizes very easily and therefore estrogen buildup and side effects can become an issue for users sensitive to these problems or those choosing to use a high dose of this compound. Therefore, when using Testosterone, bodybuilders often choose in incorporate an anti-estrogen such as Anastrozole, Proviron, Tamoxifen to help keep estrogen related side effects to a minimum. Extremely sensitive users, or users using very high doses (800-1200mgs) might find that stronger anti-estrogens such as Letrozole or Exemestane are more suitable. Androgenic side effects such as oily skin are also possible while taking Testosterone. Those looking to bulk up, often add this drug with other steroids such as deca durabolin and/or equipoise, along with an oral compound such as dianobol or anadrol.

Description:
Formestane (Lentaron) is a type I, steroidal aromatase inhibitor. It is used in the treatment of estrogen-receptor positive breast cancer in post-menopausal women. It is available as an intramuscular depot injection.

Formestane is often used to suppress estrogen production from anabolic steroids or prohormones. It also acts as a prohormone to 4-hydroxytestosterone, an active steroid which displays weak androgenic activity in addition to acting as a mild aromatase inhibitor.

Formestane has poor oral bioavailability and as such is no longer popular as many orally active aromatase inhibitors have been identified.

It is selective.
