Letrozole (Femara) and Arimidex are the two most popular aromatase inhibitors of the 3 major AIs, with Letrozole being the second most popular. Letrozole has demonstrated some very incredible efficiency in the reduction of Estrogen, more so than the other two major aromatase inhibitors. In comparison with the Arimidex, Letrozole has been found to be 10 – 20 times the strength of Arimidex, and although Letrozole doses are equally as effective as Aromasin, it operates through a different pathway in order to be highly effective in its own right. However, the context that an anabolic steroid using athlete or bodybuilder is slightly different from the medical and clinical application of Letrozole or any aromatase inhibitor, and this is what any anabolic steroid user is most concerned with: the proper Letrozole doses for Estrogen control, how to utilize Letrozole doses, and the different manners in which Letrozole doses can be used.


It must first be understood that Letrozole is an aromatase inhibitor, with a wide variety of application in terms of Estrogen control. As an aromatase inhibitor, it holds the ability to exert control over literally all of the potential Estrogenic side effects that anabolic steroid users attempt to avoid or eliminate. The standard protocol (or general rule) for the use of all aromatase inhibitors should be the following:

Attempt to avoid the use of aromatase inhibitors at all costs unless absolutely necessary. If the use of an aromatase inhibitor is necessary, utilize it only when required, and attempt the lowest possible dose for the purpose of Estrogen control rather than Estrogen elimination.


This is extremely important and must be remembered by all readers investigating the use of aromatase inhibitors. The fact of the matter is that the use of aromatase inhibitors, whether it be the three primary AIs (Arimidex, Aromasin, and Letrozole) or any others, will exert negative effects on the body if utilized when they are either unneeded, or when they are utilized too much at Letrozole doses that are too high.

Remember that the reason for the use of an aromatase inhibitor should at all times be for the purpose of Estrgen control rather than Estrogen elimination, as the complete and total reduction of all Estrogen levels in the body can and does result in deleterious effects on the human body. This will be further explained in the side effects portion of this profile, but a general description is that these compounds (aromatase inhibitors) deprive the body of a very important hormone (Estrogen) that is important for various essential bodily functions at normal physiological levels.


Letrozole dosage

1. LML BIO Dosage

Letro is approved by the FDA for the treatment of post-menopausal female breast cancer patients as an adjunctive treatment when first-line treatments (such as Nolvadex) have failed to work. It is also approved for the extended treatment for post-menopausal female breast cancer patients after 5 years of Nolvadex administration. Letrozole is also approved for the treatment of post-menopausal female breast cancer patients that are exhibiting symptoms of Estrogen receptor unknown breast cancer. This is a breast cancer condition in which the diagnosis indicates that it is unknown as to whether or not Estrogen is the culprit, or whether or not the breast cancer is aggravated by Estrogen. Finally, it is also approved for the treatment of post-menopausal female breast cancer patients for whom all other anti-Estrogen compounds have not worked (this includes SERMs and all other AIs). Letrozole is often the last-resort and final treatment attempt for breast cancer patients when all else has failed.

The Letrozole dosage for breast cancer treatment in all cases are that of 2.5mg daily.


2. Letrozole Dosage During Anabolic Steroid Use

Letrozole in particular cannot be categorized into the three tiers of users (beginner, intermediate, and advanced) as normally outlined and listed in common profiles of the different compounds and drugs. This is due to the fact that Letrozole is an ancillary drug not particularly used for the purpose of performance enhancement, but instead is utilized to combat or mitigate various Estrogen-related side effects when aromatizable anabolic steroids are utilized.


In some instances, Letrozole doses might possibly also be utilized to increase the endogenous secretion of Testosterone in men, which allows this compound to be utilized as an ancillary medication during PCT (Post Cycle Therapy) phases following the end of an anabolic steroid cycle, but its use on its own for this purpose is not very common and is unlikely to produce noticeable performance enhancing effects. Letrozole’s use as an endogenous Testosterone stimulating agent will be further covered in detail shortly.


For the purpose of Estrogen control during a cycle: Letrozole is the most effective aromatase inhibitor utilized to reduce levels of circulating Estrogen in the body during a cycle involving the use of aromatizable androgens (anabolic steroids that have an affinity to bind to the aromatase enzyme and undergo aromatization into Estrogen). This has been outlined previously in the introduction. Letrozole doses for this purpose cover a very wide range, and how much Letrozole is required (and how often) is also largely dependent on the doses of aromatizable anabolic steroids used, the individual’s sensitivity to aromatase inhibitors, and the rate of aromatization of the anabolic steroids used. With this being said, the general range of Letrozole doses are approximately 1.25mg – 2.5mg daily. There does exist a very large margin for adjustment and user preference when it comes to Letrozole dosages, as each individual should slowly adjust their dose depending on how they feel the body is responding. This is especially so for Letrozole, which is the most powerful and potent AI of the three. Even 1.25mg daily is too much for many anabolic steroid users, and often times the recommended dose is actually 1.25mg every other day, and often can be even less frequent especially considering the half-life of Letrozole is that of 2 – 4 days. These Letrozole doses can easily be adjusted if the user feels it is not working well enough, or if it is reducing Estrogen levels too much.


Always remember that the idea with the use of aromatase inhibitors is to control Estrogen levels and bring them back to normal physiological levels as opposed to the complete reduction and/or elimination of them, which will cause problems in the body.


For the purpose of gynecomastia reversal/elimination: It has been a proven fact both in clinical data involving mice, as well as anecdotal evidence that Letrozole is indeed capable of reversing and eliminating gynecomastia progression. This is one particular effect that is slightly more unique to Letrozole itself. It should be known that other aromatase inhibitors can exhibit this effect as well, but if gynecomastia has progressed beyond a certain point, it will be irreversible and removal must be done through surgery. Letrozole does not hold the ability to remove fully developed gynecomastia, but has demonstrated the ability to potentially reverse gynecomastia at development stages far beyond the reversal capabilities of Aromasin (Exemestane) or Arimidex (Anastrozole). One particular study on mice demonstrated that receptor overexpression (caused by Estrogen) that induced mammary gland changes were destroyed with even low doses of Letrozole. Although these studies were performed on mice, there are plenty of anecdotal reports of bodybuilders developing gynecomastia who have utilized Letrozole in combination with a SERM (such as Nolvadex) that have effectively reduced and eliminated progressing gynecomastia where all other treatment attempts have failed. Although gynecomastia reversal is not guaranteed (especially depending on circumstances), it is worth a try for individuals who especially have recently developed gynecomastia (the sooner the treatment following gynecomastia development, the better).


3. Female Letrozole Dosage

Female anabolic steroid users seldom need to worry about rising Estrogen levels, but for those that are competitive bodybuilders that must eliminate the water retention associated with Estrogen that causes the unwanted bloating, the use of an aromatase inhibitor such as Letrozole (Femara) might be necessary. However, because of the immense strength of Letrozole, it is recommended that females attempt the use of one of the other two major aromatase inhibitors prior to resorting to Letrozole use. This is because it has been demonstrated medically that aromatase inhibitors in fact do impact Estrogen reduction in females far greater than that of males.


It is important to remember that medically, Letrozole is approved for use in post-menopausal females only, who possess a very different shift in hormone levels compared to pre-menopausal females. Even among post-menopausal female breast cancer patients, Letrozole is utilized as the absolute last resort last-line of defense against breast cancers after all other treatments and drugs have failed. Because medical data has suggested that aromatase inhibitors are far more effective in females than males (depending on the aromatase inhibitor in question used), Letrozole doses of 1.25mg every other day or once every two days should suffice and in fact often times become too much, in which case the individual might feel the need to adjust to either a lower dose or a lesser frequency of administration.


4. Letrozole Dosage for Increased Endogenous Testosterone Secretion and PCT (Post Cycle Therapy)

It has been previously mentioned that Letrozole holds the potential to raise the endogenous production of Testosterone levels in men. This is through the negative feedback loop of the HPTA (Hypothalamic Pituitary Testicular Axis), whereby it has been found that excess Estrogen in men can and does suppress the output of endogenous Testosterone, leading to hypogonadism. Letrozole in particular in many studies has demonstrated to hold the capability to raise Testosterone levels through the reduction of Estrogen. One particular study evaluated an elderly male exhibiting sexual dysfunction issues resultant of low endogenous androgen production that was administrated with Letrozole doses, and the study concluded that Testosterone levels were restored normal physiological levels and sexual function was restored. In this study, LH (Luteinizing Hormone) and FSH (Follicle Stimulating Hormone) had increased, while SHBG (Sex Hormone Binding Globulin) had decreased. LH and FSH are the two important gonadotropins that signal the testes to begin production of Testosterone, while SHBG is a protein that binds to androgens and renders them inactive (in much the same way aromatase inhibitors will bind to the aromatase enzyme and render it inactive). The same study had determined that Letrozole was so effective at Estrogen reduction in men that the test subject’s Estrogen levels were in fact undetectable.


One can easily conclude, based on the data provided, that Letrozole would be an effective addition to the necessary increases in Testosterone required during the post-cycle weeks following cessation of anabolic steroid use. There is one issue with the addition of Letrozole in a PCT program that includes the use of SERMs such as Nolvadex and Clomid, which are known as absolutely essential components to a PCT program. This same problem is evident in Arimidex, but not in Aromasin (Exemestane). The problem is that Letrozole and Nolvadex (as well as Arimidex and Nolvadex) both directly counteract one another. One study has demonstrated that when Letrozole is utilized with Nolvadex, Nolvadex will decrease blood plasma concentration of Letrozole (as well as Arimidex, another commonly used aromatase inhibitor).


The conclusion here is that the use of Letrozole and Nolvadex together is a very bad idea. Therefore, Letrozole’s use as a PCT component is very limited if used in conjunction with Nolvadex. Instead, its use with HCG might be more beneficial, but this also presents the problem of the essential component of a SERM for the purpose of endogenous Testosterone stimulation being absent. Therefore, a better aromatase inhibitor choice for PCT instead of Arimidex would be Aromasin (Exemestane), because unlike Letrozole, Aromasin has it has not been demonstrated have its effectiveness eliminated or reduced by Nolvadex as shown in studies


Proper Administration and Timing of Letrozole Dosages

There are no special considerations with administration of Letrozole doses, and it can be taken at any time of the day (morning, night time, before, during, or after meals).

One important note to make with Letrozole doses is that it in fact takes 60 days before blood plasma levels of Letrozole have reached its optimal peak level, even though its half-life is approximately 2 – 4 days. Letrozole possesses the longest required window of time for blood plasma levels to reach optimal peak out of all three major aromatase inhibitors (conversely, Arimidex and Aromasin require 7 days in order for optimal peak blood plasma levels to be reached).

Expectations and Results from Letrozole Dosages


Because Letrozole is by far the most effective aromatase inhibitor with the ability to reduce Estrogen levels to undetectable levels, users must be cautious to ensure that these Estrogen levels do not plummet too low to be considered healthy. As Estrogen levels decline, the physique may take on more of a harder ‘grainier’ and ‘ripped’ look due to the loss of water retention provided by Estrogen. This results in very little to no subcutaneous fluid, which will present the underlying musculature more prominently. The one exception to the issue of complete Estrogen elimination is in competitive bodybuilders that require almost total elimination of water retention on the competition day. In such a situation, Letrozole might possibly be the best aromatase inhibitor to use above all other AIs at a full dose utilized by a competitive athlete only days leading up to a competition for the physique altering reasons previously stated. Near-total reduction of Estrogen should not be maintained for more than a 48 hour period for health reasons.


Letrozole Application for post cycle:


Letrozole carries with it many benefits that may aid the individual in HRT, TRT, a Post Cycle Therapy (PCT) plan, as well as during the actual cycle process itself in the name of side-effect prevention. Further, Letro also brings about another benefit revolving around physique conditioning and this can be and is often very important to many competitive bodybuilders during their contest prep time.


For the HRT or TRT patient if he is prescribed Letrozole it will more than likely be because he suffers from low testosterone. Low testosterone can affect the individual in a host of negative ways such as increasing body fat, a loss of muscle mass and strength, loss of libido and sexual function, depression, lack of energy and a host of other issues. As Letrozole actively stimulates testosterone production this medication is sometimes used for that very purpose but more times than not, while it will increase production, for the man who truly suffers from low testosterone it will not be enough and some form of exogenous testosterone must be applied.


When we look at the PCT process it is similar to the individual who is supplementing with Letrozole for HRT; the purpose of a PCT is to stimulate natural testosterone production. When we supplement with anabolic androgenic steroids our natural production is suppressed; the total duration of the cycle, the compounds used and the total dose will affect this to a degree, some steroids suppress more than others but suppression will exist regardless to some level. For this reason one could supplement with Letro during his PCT to stimulate the release of LH thereby starting natural testosterone production yet again; however, this is not a practice we are particularly fond of and for good reason. The primary purpose of a PCT plan is to stimulate natural testosterone production but it is not the only purpose; the total purpose is to return the body back to normal and this is difficult to do with Letro. Letrozole greatly reduces estrogen in the body and while this is a hormone that can cause unwanted side-effects for the anabolic steroid user it is also a hormone we need for proper bodily function. We cannot “normalize” when our estrogen is so readily suppressed and it is for this reason we will always prefer SERM’s for PCT needs over any AI, including Letrozole.


Without question Letrozole’s primary beneficial role is during the actual anabolic steroid cycle itself. Recall from above, many anabolic steroids convert into estrogen and it is by this conversion that causes a buildup of estrogen in the body that some of the most common and well-known anabolic steroid side-effects exist. The conversion of estrogen is caused by the aromatase enzyme or aromatase process and when this occurs such side-effects as Gynecomastia (male breast enlargement) excess water retention or bloat, high blood pressure and cholesterol issues may occur. By supplementing with Letro while on cycle we can prevent these problems from occurring or at least greatly aid in the process; cholesterol and blood pressure will also be largely determined by your overall lifestyle. However, unless the individual is ultra-sensitive to Gynecomastia if he supplements with Letrozole the odds of Gyno as it is commonly known occurring is very, very slim. Further, the same can be said of water retention; if an individual is bloated and watery while on cycle and using Letrozole he’s probably simply eating too much and estrogen buildup is not the problem. To give you an idea of how powerful Letro is as a side-effect preventer, if an individual is supplementing with anabolic steroids and Gynecomastia starts to flare up, if the individual starts supplementing with Letrozole when the symptoms appear, in most cases the flare up will be reversed and no Gyno will exist. No, it will not help the ultra-sensitive but most it will. Very few medications can boast such a claim; while many supplement with Nolvadex, a very good SERM for Gyno prevention, if symptoms show all the Nolvadex in the world won’t help you.


The next and last true benefit is directly linked to the appearance of the physique and for most this encompasses the world of competitive bodybuilding. As Letrozole actively reduces the total estrogen in the body many bodybuilders will supplement with Letro during a contest prep diet, for the less estrogen you have the harder the physique will be; assuming you are lean. Most bodybuilders who follow this method will generally run a steady every other day dose for several weeks before the show and in many cases increase it to daily the final 7-14 days to provide this effect. Without question contest preparation with Letrozole will aid greatly in providing a harder and dryer physique; two important components of many in competitive bodybuilding.
