S-23 – Product Information
According to the available studies, S-23 induced infertility in all rats it was exposed to. These effects are dose-dependent and temporary, meaning the rats regained fertility following treatment. This shows the potential of S-23 as an oral male contraceptive.
In the abovementioned study, S-23 produced other beneficial, desirable effects. For instance, researchers observed that S-23 displays a stronger affinity to androgen receptors as compared to other popular compounds like Andarine.
S-23 SARM also has an ideal anabolic-androgenic ratio, allowing it to produce a good number of positive effects without any severe complications. A couple of those effects were increased bone mineral density and lean muscle mass.
Therefore, while S-23 may be effective as a potential male birth control pill, it can also be used for other purposes, especially among patients with chronic conditions that lead to muscle wasting. PureRawz sells S-23 SARM for laboratory research use only.

What is The S-23 SARM?
S-23 is a selective androgen receptor modulator (SARM).
SARMs are compounds that selectively target androgen receptors (ARs) in certain tissues, but not in others. They have similar anabolic properties to anabolic steroids but with reduced androgenic (producing male characteristics) properties. [R]
In a rat study, S-23 has demonstrated potential use for hormonal male contraception. Either no sperm or very low sperm counts in the testis were successfully achieved in animals that received combination treatment. Plus, a 100% infertility rate was observed. [R]
S-23 also increased bone mineral density and lean mass but reduced fat mass in a dose-dependent manner. Its beneficial effects on muscle, and tissue selectivity, and favorable pharmacokinetic properties make S-23 a strong candidate for use in oral male contraception.
How Does The S-23 SARM Work?
Similar to other SARMs, S-23 selectively binds to androgen receptors in the muscles and bones, while only mildly affecting the prostate and other tissues. This was also evident in the abovementioned study, in which S-23 partially maintained prostate and seminal muscles.
Animal studies have shown that S-23 SARM has a half-life of 11.9 hours. It has also been found that S-23 reaches peak concentrations within 4 hours of administration. However, in the absence of clinical studies, its absorption in humans is unknown. [R]
S-23 SARM Research
No human studies on the use of S-23 have been published to date. As a result, we have to rely on animal and cell-based studies to explore the potential effects of this research chemical.
In the latter, S-23 produced lean muscle gains, increased sexual desire, and achieved a dose-dependent suppression of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). PureRawz sells S-23 for research use only and not for human consumption.
S-23 and Male Contraception
A rat study was conducted to determine the effects of combined S-23 and estradiol benzoate (EB) treatment. It found that the combination treatment is an effective and reversible regimen for male hormonal contraception in rats.
Furthermore, the beneficial effects of S-23 on the muscle, tissue selectivity, and favorable pharmacokinetic properties make it a strong candidate for use in oral male contraception. [R]
S-23 and Muscle Growth
In the abovementioned study, S-23 also increased lean muscle mass in mouse models. [R]
In another study, the effect of S-23 and Testosterone on glucocorticoid-induced muscle atrophy was observed. Glucocorticoids are the most widely used anti-inflammatory drugs in the world. However, their prolonged use might lead to undesirable side effects, such as muscle wasting or muscle loss.
This study confirmed that the atrophic effects of glucocorticoids are mediated at least partially via the suppression of IGF-1 signaling. More importantly, it found that the suppression was partially or completely inhibited by TP and S-23. These results confirm the anabolic effects of S-23 on protein synthesis. [R]
S-23 and Bone Density
The pharmacologic effects of S-23 were characterized in male rats as an animal model of male hormonal contraception. S-23 showed high binding affinity and was identified as a full agonist in vitro. This potential male contraceptive also increased bone mineral density in research subjects. [R]
Bone mineral density (BMD) is a crucial indicator of your bone health. A low BMD means you have an increased risk of osteoporosis, fractures, and other bone-related diseases. Medical practitioners use the BMD test to identify your risk of osteoporosis. [R]
S-23 and Fat Loss
In the abovementioned animal study, animals treated with estradiol benzoate (EB) and S-23 were leaner than intact controls with lower average weight and significantly less percentage of fat mass. A high inverse correlation existed between the dose rate of S-23 and the percentage of fat mass in rats.
S-23 and Female Sexual Motivation
A rat study set out to investigate the effects of S-23 on the sexual motivation of ovariectomized female rats. All females that received S-23 demonstrated a significant increase in sexual motivation, with similar increases seen at doses ranging from 0.05 mg/day to 3 mg/kg/day. [R]
