S-23 Description:
S23 or (2S)-N-(4-cyano-3-trifluoromethylphenyl)-3-(3-fluoro-4-chlorophenoxy)-2-hydroxy-2-methyl-propanamide is a new SARM from GTX, Inc. which is developed as a possible male hormonal contraceptive. It links to the androgen receptor (AR) more intensely (with a Ki of 1.7nM) as compared to older medicines such as Andarine.
In animal research, S23 displayed a good ratio of anabolic to androgenic effects as well as dose-dependent restraint of spermatogenesis (the course of sperm cell development) with unprompted recuperation after end of treatment.
S-23 is an investigational SARM, as a potential male hormonal contraceptive. S-23 binds to the receptor more strongly than older drugs such as andarine with a Ki of 1.7 nM, and in animal studies S-23 showed both a good ratio of anabolic to effects, and dose-dependent suppression of spermatogenesis with spontaneous recovery after cessation of treatment.
How safe is S23 ?
Many people want to know S-23’s safety before any action is made. Most of these SARMs have not yet been tested on humans, but only on rats or mice. This is also true for S-23.
SARM S-23 can be found in some webstores that sell research chemicals online. Not much is known about the working or side effects of SARMs in humans, so caution is advised. And a 2009 animal study, in which researchers at GTx tried S-23 out on rats, suggests that S-23 is a little more risky than other SARMS.
S-23 Function
S-23 not only boosted muscle mass, but also reduced fat mass, as studied. SARMs have a bit of a ‘soft’ image in the doping world. They don’t stimulate muscle growth in the way that anabolic steroids do, but many users say that they are safer.
There are no studies yet that confirm this suspicion. But that S-23 is not one of the safer SARMs – we’d be willing to wager a bottle of BCAAs on that.
S-23 halts the production of sperm in the testes. In fact it does this so well that the researchers suspect S-23 might be a good candidate for a male contraceptive. If this is the case it would probably have to be part of a cocktail that also contains an estradiol analogue, the researchers discovered. The lab animals lost their libido when they were given S-23 on its own, and only recovered this when they were given estradiol benzoate together with the S-23.
S-23 Bodybuilding Uses
Developed by GTx, S-23 is an orally active nonsteroidal SARM with a very high binding affinity to androgen receptors. This makes it stronger than other popular SARMS like Ostabolic (mk-2866) or Andarine (S-4). Therefore, the main effects of S-23 are increased muscle mass, decreased fat mass, and a decrease in the size of the prostate.
Additionally, in a study done on rats a dose equivalent to 15 milligrams (mg) for a 180lb male was shown to also increase bone mineral density, as well as promote muscle mass growth and fat loss. Hence, S-23 is versatile in that it can be used for bulking and for cutting.
S-23 DOSAGE
S-23 is new to the market, and no recommendation for dose is available. Data shows that a dose of 0.3 mg S-23 [human equivalent: 15 mg] leads to an increase in muscle mass, but that the prostate dimensions decreased. But there is no official doses for S-23 yet. We will update the dosing information when it is available.
