SARM stands for Selective Androgens Receptive Modulator. The simplest way to explain is that SARMs are hormones. They are hormones specifically designed to express specific genes. In this case, they are used to express the male gene.
To explain more deeply, SARMs are a better group of the androgen ligands. Of course, we first need to understand what is androgen and ligands.
Androgen
Androgen means male in Greek. This is the steroid hormone that maintains male characteristics. The most well-known androgen is testosterone.
Ligands
Chemistry defines a ligand as a molecule that binds to another atom to form a coordination complex.
The above mentioned terms look scientific and beyond the scope of common understanding. Explained simply, SARMs are androgens that can bind themselves to the androgen receptors in the body. They work similarly to other androgens but are more selective in choosing their target. This particular ability allows researchers to use them in clinical tests.
Comparison of SARMs and Testosterone
As mentioned earlier, testosterone is the most commonly used androgen. However, it is becoming outdated in medical practices. The reason is that testosterone produces unwanted results. On injecting, it raises the level of hormone in the blood while decreases to low level after some time. People have used patched as well but that led to skin irritation.
On the other hand, SARMs targets selectively; meaning no side effects. It only targets the tissues where the response is needed while leaving other tissues alone. This results in a customized response as needed by the medical practice or general researchers.
Why are SARMs Used?
SARMs are being used for two basic purposes. Firstly for muscle reducing ailments like cancer and osteoporosis, and secondly for hormone replacement therapy. SARMs are replacing traditional androgens like testosterone due to fewer side effects.
Uses of SARMs
The best use of SARMs is for medical purposes. The medicine industry has used them as a healthy and safe alternative for steroids.  Unlike steroids, SARMs helps improve muscle mass, bone structure improve healing of wounds.  One more advantage of SARMs is that it helps improve fat loss. All these advantages are free of harmful side effects as compared to steroids. SARMs is being used in treatments for severe diseases like HIV and Cancer.  HIV and Cancer can lead to rapid weight loss so SARMs are preferred as part of their treatments.  It is also used for slowing down osteoporosis due to its bone strengthening properties.
SARMs for Body Builders
Body builders mainly depend on gaining lean muscular advantage. They can use SARMs to lose fat mass and build lean body mass. SARMs are good choice for body builders instead of steroids. Steroids do produce great performance results but long-term use can be risky. Steroids work quickly but have as much side effects. Moreover, use of steroids is illegal in many situations and circumstances.
SARMs is surely a revolutionary change in the field of androgens and steroids. The advantages are better and risk free.
