Description
Femara (Letrozole), like most of the AIs we look at for using alongside anabolic steroids, was also developed for the medical treatment of breast cancer in post-menopausal women.
The reason it is only used in women of such an age is due to its powerful estrogen blocking ability which would have serious health implications for pre-menopausal women, but for male steroid users it is this trait that makes AIs like Letrozole so appealing as we aim to combat the adverse effects of estrogen when using aromatizing steroids.
Femara (Letrozole) can lower your overall estrogen levels because it blocks the aromatase enzyme. This contrasts with the other popular category of estrogen control drugs for steroids users, SERMs, which only target very specific areas of the body. This allows Letrozole to combat a wider range of estrogenic side effects caused by steroids, with the two main ones being gynecomastia and water retention.This will also help prevent the high blood pressure that can come along when excess water retention is not addressed.
Dosage Instructions
2.5 mg – 5 mg / day
Even at very low doses Letrozole is a potent drug so you do not require a lot of it to benefit from its full effects. Unlike with many of the other AIs or SERMs you might use as a steroid user where doses are normally higher than those used for medical treatment, with Letrozole we can get away with using a similar dose or even lower than is administered when the drug is used medically.Letrozole Dosage During Anabolic Steroid UseMaking the mistake of taking too much Letrozole during steroid use will have no benefit and bring about negative effects, like fatigue. So, it’s critical to maintain a sensible dose.With a medical dose usually around 2.5mg daily, we would look at no higher than that and most of the time even lower. To protect from estrogen related side effects during steroid use a dose of as low as 0.5mg to 1.25mg every two days is often enough for excellent estrogenic related protection for most men.Only if you are experiencing early signs of gynecomastia would increasing the dose at this time up to 2.5mg per day can potentially even fully reverse the symptoms; but be prepared for a noticeable zap in energy during this time. Once gyno symptoms subside it’s important to reduce your Letrozole dose back down to regular estrogenic protection levels.
Female Letrozole Dosage:Increased estrogen levels are not anywhere near as great a concern for female steroid users as it is for males. The main reason for using an AI like Letrozole by females would be to mitigate water retention, especially for competitive bodybuilders or physique athletes where this is most important.
In fact, Letrozole is not recommended as a first choice for females due to its potency in reducing estrogen so much, hence why it is not used medically by females who have not gone through menopause. Females who are determined to use this AI are advised to dose at just 0.5mg every other day and gauge results and effects from there.
Letrozole Dosage for Increased Endogenous Testosterone Secretion and PCT:This AI may have some ability to raise testosterone levels mainly through its ability to reduce estrogen. Both luteinizing hormone and follicle stimulating hormone have shown to be able to be increased by Letrozole and these are essential to the production of testosterone.So, while a reduction of estrogen is important for bringing about a rise in testosterone levels, this is a fine balance in men and reducing estrogen too low can actually have the opposite effect with testosterone not able to increase to a normal level if estrogen is suppressed too powerfully, which Letrozole has the ability to do.For this reason, many will choose not to make use of this drug during post cycle therapy at all, in favor of using a SERM like Nolvadex. However, if you find that Letrozole is preferable for you for post cycle therapy use, a low dose similar or lower to that stated above for during your steroid cycle is the only way to reduce the risk of very low estrogen occurring.Making use of Letrozole alongside Nolvadex, which is a staple in PCT for most men, results in both drugs making the other less effective. Combining these drugs is not recommended for PCT and therefore most people will opt simply to use the better PCT option in the SERM Nolvadex while enjoying the benefits that Letrozole can provide during the steroid cycle only.
Effect on Cycle
Letrozole Effects for Gynecomastia and Estrogen Control:Letrozole is such a powerful AI and so effective at controlling estrogen that some steroid users have reported being able to successfully reverse the effects of gyno when using this drug.
Even so, it is always preferable to try and prevent gyno from rearing its head at all rather than depending on any drug to reverse it; because while some people might have luck with this when using Letrozole, others will find that more advanced gyno is still not reversible without surgery.Letrozole will reduce the entire circulating levels of estrogen in the body, unlike SERM drugs which will target specific receptors and are most useful for controlling gyno – while Letrozole will also be powerful for controlling water retention which is the other main adverse effect of steroid use that we all want to avoid.When using Letrozole you can expect your estrogen levels to be reduced considerably as this is the most powerful AI we can access currently. In fact, it could result in your estrogen dropping too low at times (yes, this can be an issue for men as we do require some small amount of estrogen for normal functioning). But during steroid cycle your main aim with an AI is to reduce, minimize and ultimately prevent the estrogenic side effects that are almost certain to come about when using steroids that aromatize.There are additional benefits to this estrogen controlling power of Letrozole too: because it means you can prevent water retention, your physique will take on a much harder, drier and ripped appearance because you’re not holding on to water. This can make Letrozole particularly useful for competitive bodybuilders who want to eliminate as much fluid retention as possible and Letrozole is the best AI to help with this goal.
Letrozole vs Arimidex for PCT:Letrozole and Arimidex are very similar compounds. Both are nonsteroidal aromatase inhibitors, and both are favored by anabolic steroid users to prevent estrogenic side effects. Both drugs have a similar side effect risk profile.
Out of these two AIs, Arimidex generally takes the lead as being more widely used by bodybuilders, but this can come down to several factors including availability, cost, and wanting to follow in the path of what friends and online acquaintances might recommend.
Side Effects
Common side effects of Femara include:
Hot flashes
Warmth in your face or chest
Hair loss
Joint/bone/muscle pain
Tiredness
Unusual sweating or night sweats
Nausea
Diarrhea
When the Letrozole dose is too high we see a great increased risk of fatigue and this comes about because estrogen levels are reduced too low – men still require some estrogen at low levels to function normally and because Letrozole is so powerful at reducing estrogen, taking too much can lower your levels beyond what is required for the central nervous system to operate normally – bringing on potentially chronic fatigue.
This can be rectified efficiently and easily by reducing your Letrozole dosage until the fatigue subsides as estrogen rises slightly and remaining at the more appropriate dose from then on.
Pain in the Bones or Joints. Lowering the dose should eliminate this side effect without any harm done.
