S23 SARM: A Potent Nonsteroidal Selective Androgen Receptor Modulator
S23 SARM is a nonsteroidal selective androgen receptor modulator, widely regarded in anecdotal reports, due to its high binding affinity to the androgen receptor, making it the most potent SARM available, nearly as potent as anabolic steroids. It is being studied for its effects on lean muscle gains, bone density, fat loss, sex drive, and as an oral male contraceptive. The oral bioavailability of S23 is ~96%, peak levels are achieved at about 4 hours, and the half-life of S23 is 11.9 hours.

Why buy S23 SARM from Sports Technology Labs?
If you are trying to figure out where to buy S23 online, widely regarded as the strongest SARM, there certainly seem to be plenty of choices out there. However, not all companies offering S23 for sale are alike—or equally trustworthy. To buy liquid S23 from a randomly selected pharmaceutical company or website is dangerous, even if the price looks reasonable, because you can’t be sure about their quality-control processes.
Sports Technology Labs is the best place to buy S23 online because of our consistent, verifiable, high-quality products, safer bottling and packaging, fast shipping, and excellent customer service. Our S23 is also available in pure powder form.

S23 Mechanism of Action
S23 mimics the action of testosterone in muscles and bones and may stimulate protein synthesis and muscle growth. S23 is a relatively new SARM and has never been clinically tested in mammals, so the safety profile of S23 has not been established. SARMs studies indicate that they may induce liver damage, fertility, and, for males, a reduction in natural testosterone levels.
Research Demonstrated Increased Bone Mineral Density
The rat model also demonstrates an increase in bone mineral density from S23 SARM administration. Low quantities appeared to work equally well as high quantities. Bone mineral density increases are relatively commonplace with the administration of SARMs; however, S23 may be particularly effective in this regard.
Research Has Shown Sexual Activity and Drive in Postmenopausal Female Rats.
A study on postmenopausal female rats demonstrated that most SARMs were able to increase sexual activity and drive, with S23 in particular causing the most significant increase in sexual motivation without inducing growth in the uterus and uterine lining. Males, however, may experience the opposite effect due to S23’s tendency to reduce natural testosterone levels as well as its higher binding affinity for the androgen receptor.
Effects on Lean Muscle Mass and Body Fat
This study also found that S23 increased lean muscle mass and decreased body fat in a quantity-dependent manner, and was able to outcompete the catabolic effects of estradiol benzoate administration. Another rat study found that S23 prevented fast-twitch and slow-twitch muscle loss from glucocorticoids, indicating that it may have significant anabolic effects.
Potential Male Contraceptive Agent
It is presently being researched as a potential male contraceptive agent in rats. During a study in rats, it caused a temporary interruption in fertility in all specimens tested. While this effect was reversed in rats, it is essential to note that this product has never been tested in mammals, and it is unknown if it interrupts fertility temporarily, permanently, or not at all. While S23 SARM has a high oral bioavailability, it is essential to note that in this study, these rats were injected with S23.
