Applications & Main Function


Pure Letrozole raws and pure Femara raws are pure Steroid raws and very popular among anabolic steroid users. Letrozole is one of the most commonly used anti-estrogens among steroid users during steroid use to combat possible estrogenic related side effects. It is so effective as an anti-estrogen in this regard many anabolic steroids have effectively reversed gynecomastia symptoms with Letrozole.


Our main products are Raw steroids, human growth hormone, Semi-finished oils, Bodybuilding peptides, SARMs raws, Anabolic steroids.Formany bodybuilders, the same anti-estrogenic effect provided by Letrozole is tremendously beneficial. While many anabolic steroids have the ability to aromatize and promote an increase in estrogen, not all anabolic steroids carry this ability. However, many common steroids carry this ability including Methandrostenolone (Dianabol) as well as all forms of testosterone. The Nandrolone (Deca Durabolin, Durabolin, NPP, etc.) and Boldenone (Equipoise) hormone also carry the ability to aromatize to a degree. Nandrolone will aromatize at approximately 20% the rate of testosterone and Boldenone at approximately 50%. While both aromatize significantly less than testosterone, it is enough to promote estrogenic related side effects. The probability is increased with Nandrolone as it carries a strong progestin nature. Progesterone has the ability to stimulate the estrogenic mechanism and can lead to gynecomastia. AI’s like Letrozole can be useful when using all the aforementioned steroids.
