Since the 1940s, scientists have been modifying the testosterone molecule to find solutions to diseases that cause large muscle losses, such as cancer and osteoporosis. They are also looking for alternatives to alternative testosterone therapy. It was in this quest that they discovered Sarm (selective modulator of the androgen receptor).
What distinguishes SARMS from other molecules, such as steroid hormones? In fact, they are not so different except that SARMS has an advantage, it has no adverse effects since they affect the muscles and bones. In fact, SARMS has all the positive properties of steroids, but none of the negatives. So with SARMS, there is no prostate cancer, no hair loss, no acne, no gynecomastia, no high blood pressure, no hepatic toxicity, no cholesterol problems, no heart enlargement or natural testosterone suppression. Although absorbed orally, there is no risk of hepatic toxicity, since the molecule is not methylated in C-17.
Finally, SARMS can be beneficial for any athlete who wants to gain muscle mass, strength and accelerate fat loss without risk to health. When doing your research, keep in mind that there are several SARMS with different effects.
There are 2 that you will know that, in fact, they are not SARM. It is cardarine (GW501516) which is part of the PPAR family (peroxisome proliferator-related receptor) and nutrobal (MK-677) family that is part of the growth hormone secretagogues family.
