High Purity Raw Steroids Powder Formestane / Lentaron CAS 566-48-3 Anti Estrogen Health Steroid

 

 

Abstract

 

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.

Lentaron 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.

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

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.

Indications/Purpose

 

Aromatase converts androstenedione to estrone, and also converts testosterone to estradiol. Lentaron is often used to suppressestrogen production during anabolic steroids and prohormone cycles. Due largely to Lentarons similarity to androstenedione, it also acts as a prohormone to 4-hydroxytestosterone , an active steroid which displays weak androgenic activity in addition to serving as a mild aromatase inhibitor.

 

Male bodybuilders and athletes also use it to prevent estrogenic side effects from anabolic steroids, to improve fat loss, and to increase muscle definition while dieting. However, several conclusive studies have demonstrated Lentarons estrogen blocking inferiority when compared to third generation AIs like Arimidex and Femara so its far less popular.

 

 

Dosage

The most common version of it sold was in a topical gel form and it was dosed at 100-200mgs per application. Users would apply it onto clean, dry skin and rub in thoroughly; usually on the thighs or upper arms. It took 1 to 5 minutes to dry.

The injectable version for both breast cancer purposes and bodybuilders is 125mgs twice per week or 250mgs once per week.
