Letrozole Description
Letrozole is an anti-estrogen of the Aromatase Inhibitor (AI) family and is one of the most potent and powerfully effective of all AI’s.
Letrozole was first developed in an effort to combat breast cancer in post-menopausal women. In fact, it would prove to be virtually identical to the already popular AI in Arimidex (Anastrozole). While intended for breast cancer treatment, like many AI’s, it has found a welcomed home 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.
Letrozole Application
Letrozole has been used for ovarian stimulation by fertility doctors since 2001 because it has fewer side-effects than clomiphene (Clomid) and less chance of multiple gestation. A Canadian study presented at the American Society of Reproductive Medicine 2005 Conference suggested that letrozole may increase the risk of birth defects.[citation needed] A more detailed ovulation induction follow-up study found that letrozole, compared with a control group of clomiphene, had significantly lower congenital malformations and chromosomal abnormalities at an overall rate of 2.4% (1.2% major malformations) compared with clomiphene 4.8% (3.0% major malformations). Despite this, India banned the usage of letrozole in 2011, citing potential risks to infants.In 2012, an Indian parliamentary committee said that the drug controller office colluded with letrozole's makers to approve the drug for infertility in India and also stated that letrozole's use for infertility was illegal worldwide; however, such off-label uses are legal in many countries such as the US and UK.
Letrozole Benefit
Femara is a powerful Aromatase Inhibitor that was developed to fight breast cancer. For athletes and bodybuilders, it is a drug used to combat the estrogenic side effects of anabolic steroids water-retention, acne and gynocomastia. It will also raise testosterone levels because of the lowered estrogen in the body. Side effects from include a lowered sex drive and continuous use can lead to lowered lipid function and an impaired immune system.
Letrozole is an aromatase inhibitor. It works by reducing the total amount of estrogen produced primarily in the body. This helps to starve cancer cells by depriving them of estrogen.
Letrozole cycle
For the anabolic steroid user, Letrozole doses will normally be much lower. Even with the use of anabolic steroids, a 2.5mg dosing will normally be too high and could potentially drain the individual of energy. Most men will find 0.5-1mg every other day to be more than enough. When used as an anti-estrogen in low testosterone treatment plans, even less may be needed. For the competitive bodybuilder, the final 7-14 days before competition, a full 1mg per day leading up to the show can be a solid dose and will greatly help with dryness and a tighter look.
Letrozoles has a 2-4 day half-life, and it needs to be taken for up to 60 days to get a steady blood plasma level, using Letrozolesat such a low dose does happen to make it a very good economic choice compared with other aromatase inhibitors.
