To start, let’s describe what a SARM does. There are three type of chemicals that act on the androgen receptor (AR). One is the an AR antagonist, which is a chemical that binds to the receptor to prevent it from activating. The second is an AR agonist, which binds to the receptor and detaches, then binds again, over and over. An example of an AR agonist is testosterone, each time the AR is bonded with testosterone, a signal is sent out to activate a particular set of genes. The more testosterone that is in the system, the more AR binding will occur. The third is an AR modulator, or basically a molecule that attaches to an AR and changes its structure to react however it wants.
