Letrozole is not an anabolic steroid in any shape or form but belongs to the aromatase inhibitor family and by its very nature its primary mode of action is just that; inhibiting aromatase but as we’ll see it has secondary qualities. Unlike many commonly used Selective Estrogen Receptor Modulators (SERM’s) Letrozole directly affects estrogen by blocking the aromatase enzyme or better yet by blocking or inhibiting the aromatase process. By its nature Letro greatly reduces the amount of estrogen in the body and prohibits estrogen from conversion as is a common occurrence with many anabolic androgenic steroids. Many anabolic steroids convert into estrogen, it is their nature and a prime example is the powerful anabolic androgen Testosterone. It is this estrogen conversion that can lead to many unwanted side-effects as we will see shortly. How powerful is Letrozole; well it can reduce the total amount of estrogen in your body by as much as 98%, again, making it the most powerful aromatase inhibitor of the common three with only the Cytadren medication being more powerful but not necessarily more advantageous.
By their nature aromatase inhibitor’s also carry with them other properties as they actively increase natural testosterone production by way of stimulating both the Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH) but it is LH that carries with it the brunt of the advantage. No, it will not increase testosterone production to the levels one might increase them to through injectable use but there are benefits to stimulating natural production via Letro and we will find they are more beneficial in-terms of both recovery and the HRT or Testosterone Replacement Therapy (TRT) process.
The Side-Effects of Letrozole:
All medications of all types carry with them a potential for negative side-effects and Letrozole makes no exception; however, in general this is a fairly well-tolerated medication in most. The most common side-effect to Letro use is decreased libido or sex drive, as estrogen is suppressed and as estrogen is a needed component for a healthy sex drive, too little can cause a problem. Even so, for the performance enhancer, if he has enough testosterone in his system and does not abuse the AI he will in all likelihood be absolutely fine in this regard, it is HRT patients who use Letro or performance enhancers that don’t supplement with any or enough testosterone that may find this to be a problem. Other possible side-effects may include a weakened immune system estrogen is essential to a strong immune system and low levels for far extended periods of time can cause a problem. For this reason we must be responsible with our Letrozole use and only supplement when necessary and advised. It has also been greatly debated on whether or not Letrozole can have a negative effect on HDL and LDL cholesterol and many suspect it may in high doses and especially periods of far extended use however, such evidence is inconclusive regarding the extent but with extended use some effect is assured to occur.
