Anastrozole has no harsh side effects. Actually, affecting estradiol, it can suppress the level of the good cholesterol (HDL). However, when compared to AI like letrozole, anastrozole is preferable. Letrozole has quite a few side effects, the most common of which is erectile dysfunction. Although estradiol is known as a female hormone, men still need it. Estradiol maintains hormonal balance, participates in a great number of physiological processes and helps to gain muscle mass and strength. Such potent AI as letrozole kills almost all estradiol, disrupting the hormonal balance and causing a number of side effects, such as erectile dysfunction, joint pain, bones fragility, unwellness, etc. Anastrozole acts more smoothly and does not kill all estradiol immediately, allowing you to more finely adjust the hormonal balance.
Anabolic androgenic steroids (AAS) were initially created for therapeutic purposes, and synthetic derivatives of the male hormone testosterone. Due its great anabolic effects, these drugs are being used on a large scale, for the improvement of sports performance. In this present study, we aim to show the history of it’ use, present their mechanisms of action, more particularly its use correlate with improved body composition, muscle mass, aerobic capacity and verify their possible side effects, analyzing their use therapeutic and indiscriminate, through direct scientific research with the sports. Sources were reviewed scientific the following search engines: PUBMED, LILACS and SCIELO. The results showed that in presence of a suitable AAS and diet can contribute to increases in body weight, particularly lean body mass and muscle strength gains achieved by high intensity exercise, these effects can be further potentiated, the use of supraphysiological doses, but in the aspect of aerobic power, there are not scientific evidence to support their improvement. Regarding side effects, the use of AAS, is related to several complications in the liver, cardiovascular system, reproductive system and psychological characteristics, always assigned by the non-therapeutic and abuse of AAS. Thus we conclude that the use of AAS, are directly linked to gains muscle mass, strength, as well several side effects, always assigned to abusive and indiscriminate doses, it is noteworthy that the scientific literature, still has a certain lack of studies, mainly randomized, controlled, with supraphysiological doses in human, so many effects are still unknown.
Despite the studies that have shown the profound effects Winstrol can have on the human body, it is classified as a controlled substance in the US and many other countries due to its potential for abuse. Unfortunately, this means it is illegal to buy, sell, possess, or use Winstrol pills in the United States without a prescription from a doctor. One of the most common questions asked in steroid forums for this very reason is, “Where can I get Winstrol pills?” There are a few different methods, and each one comes with its own set of benefits and risks.
