Usage: 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 testoster levels because of the lowered estrogen in the body.
Letrozole/Femara Description:
Reduce estrogen levels: Letrozole (Femara) also does quite a few things which would be of interest to both bodybuilders and athletes.Firstly, it has been shown to reduce estrogen levels by 98% or greater.
Letrozole (Femara) reduced estrogen in the test subject to undetectable levels, and increased LH, FSH and SHBG.
Clearly this is all of interest to bodybuilders, as less estrogen in the body means less chance of certain side effects such as water-retention, Gynocomastia, and acne.This makes Letrozole (Femara) an appropriate choice for even the heaviest bulking or cutting cycles including harsh androgens.
Breast Cancer: Letrozole (Femara) was developed to fight breast cancer by inhibiting the aromatization.
Increase LH and FSH: Letrozole (Femara) can be used to raise LH and FSH (which are hormones which signal your testes to produce more testosterone).It will raise your testosterone levels via this mechanism. Again, this is of interest to athletes and bodybuilders for obvious reasons.
Letrozole/Femara Application
For pre-contest bodybuilders, Femara is almost a necessity to eliminate water retention and achieve the ripped look necessary to compete in today's bodybuilding world. However, in my experience, it is only necessary to be used for the last 4-6 weeks, to eliminate excess estrogen and water retention. After using Femara I recommend staying away from any estrogen suppression for at least a month to try to normalize the body.
Femara is a type II (non-steroidal) third generation aromatase inhibitor. Clinically it is used to treat postmenopausal women with either estrogen receptor positive or estrogen receptor unknown breast cancer. In women with breast cancer, it has been shown to reduce estrogen levels by 98% or more .
However, it's use and benefits are not limited to eliminating estrogen in women.
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.
The anti-estrogen action of letrozole has been shown to be useful in pretreatment for termination of pregnancy, in combination with misoprostol. It can be used in place of mifepristone, which is expensive and unavailable in many countries.
Letrozole is sometimes used as a treatment for gynecomastia, although it is probably most effective at this if caught in an early stage (such as in users of anabolic steroids).
Letrozole has also been shown to delay the fusing of the growth plates in mice.When used in combination with growth hormone, letrozole has been shown effective in one adolescent boy with a short stature.
Letrozole/Femara Dosing:
Anecdotally users have reported seeing good results using doses ranging from about .25mgs per day to .5mgs per day. However these doses do vary quite widely from user to user, including dosing schedules. Some have reported using the compound every other day or every third day with good results. Also, doses reported have ranged from .25mgs to as much as 2.5mgs per day.
About the dosing, you need to make a choice in combination with your body condition, or consult your trainer / doctor. This article is for reference only.
