Because many anabolic steroids aromatize, causing estrogen to build up, numerous and some of the most commonly associated side effects can occur. To combat such problems, responsible use of aromatizing steroids is the first line of defense, but artificial intelligence such as Letrozole can provide a strong advantage. By inhibiting the aromatase enzyme, estrogen buildup cannot occur, and if it cannot occur, such related problems cannot manifest. By using in conjunction with a supplemental anabolic steroid plan, side effects such as gynecomastia and excessive water retention can be avoided. Moreover, high estrogen accumulation can have a negative impact on blood pressure and cholesterol levels, and thanks to this artificial intelligence we get even greater protection.
Letrozole and testosterone

As mentioned above, Letrozole can have a very positive effect on the natural production of testosterone. For this reason, some doctors prescribe this AI to treat low testosterone levels or for people suffering from andropause. Some reports have stated that this use of letrozole can increase total testosterone by up to 50% in some men, but this is often not enough and sometimes a pointless treatment. A 50% increase may be more than welcome, but a 50% increase doesn't necessarily mean you'll be at the right level now. In most American medical circles, any total testosterone level below 300ng/dl is considered low, and in this light, if your total level is below 150ng/dl, Letrozole will not bring you back to the normal range. Furthermore, if the release of LH and FSH is not the cause of low testosterone, all the Letrozole in the world will not save you. The only true way to combat low testosterone on a TRT plan is true and direct exogenous testosterone therapy.
Letrozole and PCT

Some performance enhancers, especially in recent years, have started to supplement AI such as Letro for their post-cycle therapy (PCT) needs. The premise is simple; Letrozole promotes natural testosterone production that was suppressed due to anabolic steroid use, and since testosterone recovery is essential to a PCT plan, the problem is solved. While Letro will promote testosterone recovery, it is not the best option and also goes against the overall premise of the PCT plan. While restoring natural testosterone levels is an integral part of a PCT plan, it is not the primary goal. The primary goal of a PCT plan is to normalize the body, and with letrozole suppressing estrogen to such an extent this cannot occur. For PCT purposes, the best course of action is to use a SERM such as tamoxifen citrate (Nolvadex) or clomiphene citrate (Clomid), and in many cases with one of these SERMs combined with the powerful peptide hormone Human Chorionic Gonadotropin (hCG). If you are looking for more, if you really want to protect your gains, taking human growth hormone (HGH) can help significantly; assuming it was part of the previous cycle plan.
