Letrozole: Uses, Side Effects and Common Brands
Letrozole (Femara) is the most effective drug, representing a class of aromatase inhibitors (blockers), reducing the level of estrogen concentration, thereby increasing the gonadotropic hormones with testosterone. In medicine, inhibitors are predominantly prescribed during prophylactic treatment with male gynecomastia.
Aromatase inhibitors are used by athletes into their diet during a cycle of anabolic steroid drugs. Inhibitory drugs are taken in cases:
- Gynecomastia warnings;
- Increased levels of anabolic hormones in the blood;
- Improving the density of muscles (eliminating the negative effects of estrogenic substances);
- Eliminate symptoms of hypertension;
- Reducing estrogen pressure on the hypothalamus-pituitary-testes, which contributes to the fastest recovery.
At the beginning of the cycle, it is recommended to consider the factor that not all existing anabolic steroids are aromatized. Letrozole is mainly used when using testosterone or its derivatives, for example, Methandienone or Methyltestosterone.
