Selective androgen receptor modulators are a novel class of androgen receptor ligands. They are intended to have the same kind of effects as androgenic drugs but be much more selective in their action, allowing them to be used for more uses than the relatively limited legitimate uses of anabolic steroids.  These items signify a new era of tissue-selective androgens with an unknown potential to treat (and possibly cure) several diseases.

Comparison to Testosterone:

Currently used androgens for male hormone replacement therapy are typically injectable or skin delivery formulations of testosterone or testosterone esters. Injectable forms of testosterone esters (such as testosterone enanthate, propionate, or cypionate may produce undesirable fluctuations in testosterone blood levels, with overly high levels shortly after injection and overly low afterward. Skin patches do provide a better blood level profile of testosterone, but skin irritation and daily application still limit their usefulness.

Selective androgen receptor modulators provide the ability to design molecules that can be delivered orally, but that selectively target the androgen receptors in different tissues differently. The goal of research in this area is to allow a customized response: Tissues that are the target of the therapy will respond as they would to testosterone; other tissues where undesirable side-effects are produced will not.

Selective androgen receptor modulators are often banned in sporting games as seen as providing unfair advantage, often combined in the same class as other performance enhancing drugs such as anabolic steroids.

Additional research is needed to substantiate claims of suitable medical uses.
