Selective androgen receptor modulatorHi guys, I am starting a cutting SARM Triple Stack, and there seems to be a lot of confusion and misinformation about these remarkable research chemicals. Compared to peptides, they are delivering amazing results, yet short of AAs as well as short on sides. You may be familiar with the charts. Androgenic ratio of other AAs to give you a relative value of the AAs efficacy for bulk or cutting, as well as a peak the potential side profile. I realize the side profile aspect of such a chart wouldn't apply, by knowing the Ostarine is Any ostarine anabolic androgenic ratio given on this board is just an opinion and not to be taken ostarine anabolic androgenic ratio medical advice.
Selective androgen receptor modulator - Wikipedia
Selective androgen receptor modulators or SARMs are a novel class of androgen receptor ligands. The name follows the terminology currently used for similar molecules targeting the estrogen receptor, " selective estrogen receptor modulators ," such as tamoxifen. They are intended to have the same kind of effects as androgenic drugs like anabolic steroids 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.
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 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. SARMs provide the opportunity 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.
None of the SARMs yet developed are truly selective for anabolic effects in muscle or bone tissues without producing any androgenic effects in tissues such as the prostate gland, however several nonsteroidal androgens show a ratio of anabolic to androgenic effects of greater than 3: This suggests that, while SARMs are likely to show some virilizing effects when used at high doses e. One substantial advantage of even the first-generation SARMs developed to date is that they are all orally active without causing liver damage, whereas most anabolic steroids are not active orally and must be injected, and those anabolic steroids that are orally active tend to cause dose-dependent liver damage, which can become life-threatening with excessive use.
Research is continuing into more potent and selective SARMs, as well as optimising characteristics such as oral bioavailability and increased half-life in vivo , and seeing as the first tissue-selective SARMs were only demonstrated in , the compounds tested so far represent only the first generation of SARMs and future development may produce more selective agents compared to those available at present. For example, if the target is bone growth in elderly men with osteopenia or osteoporosis , but with no overt signs of hypogonadism , a SARM targeting bone and muscle tissue but with lesser activity on the prostate or testes would be more desirable.
