Application
Lentaron is a second generation, irreversible, steroidal aromatase inhibitor. It inhibits the aromatase enzyme responsible for converting androgens to estrogens, thereby preventing estrogen production. Breast cancer may be estrogen sensitive or insensitive. A majority of breast cancers are estrogen sensitive. Estrogen sensitive breast cancer cells depend on estrogen for viability. Thus removal of estrogen from the body can be an effective treatment for hormone sensitive breast cancers.
What is the Formestane ?
Formestane is currently one of the best legal anti-estrogens out there.It is classified as an irreversible arromatase inhibitor, meaning, it destroys the aromatase enzyme.
Formestane is a synthetic steroidal substance with antineoplastic activity.Formestane binds irreversibly to and inhibits the enzyme aromatase, thereby blocking the conversion of cholesterol to pregnenolone and the peripheral aromatization of androgenic precursors into estrogens.
Formestane is a drug that has been previously used in breast cancer treatment.Like most drugs which have some sort of phsyique usage, athletes eventually get a hold of it.Formestane is currently one of the best legal anti-estrogens out there.It is classified as an irreversible arromatase inhibitor, meaning, it destroys the aromatase enzyme.
Formestane (Lentaron) 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 mild aromatase inhibitor.
Formestane has poor oral bioavailability and as such is no longer popular as many orally active aromatase inhibitors have been identified.
