The principle of action of SARMs and steroid hormones is similar – both hormones attach to androgen receptors, promoting muscle growth. However, they have fundamental differences. Anabolic steroids affect not only muscles but also other tissues, organs, and glands. Thus, they cause the well-known "side effects" - disorders in the liver, kidneys, prostate, etc. To restore the normal functioning of the body after taking anabolic steroids, athletes use the so-called post-course therapy.SARMs are active only in muscle and bone tissue and do not affect other tissues and organs. They are also not synthesized into estrogens. An increase in muscle mass is achieved without harm to the body. Another important difference is that selective modulators are taken orally, and not only intramuscularly. SARMa is a safe alternative to traditional anabolics, which does not cause side effects and does not require a course of rehabilitation therapy after taking it. In short, they have all the advantages of traditional steroid hormones but are devoid of their disadvantages – harm to the body and the need for post-course therapy. As for me, if you aren’t a professional bodybuilder, not having reached your genetic potential, you shouldn’t use SARMs as well as prohormones. At first, reach your potential in natural bodybuilding, only then ask yourself whether you need that at all. As for me, I use only sports nutrition bought on rats.army, one of the best sellers in this field. Wide choice, affordable prices, and discounts to regular customers. Also, you can find SARMs there if you want, however, I highly recommend you not to do that as you can have unpleasant side effects during misuse.
