S-23 is a selective androgen receptor modulator (SARM) currently being investigated for both its muscle-building properties and potential as a male contraceptive. Originally developed by GTX, Inc., it shows promise in supporting lean muscle growth, fat reduction, and bone health. It is also being studied for muscle wasting, osteoporosis, and other muscle/bone-related conditions. S-23 is currently being tested as a potential male contraceptive.
Product Information
S-23 was developed by GTX, Inc. and is classified as a selective androgen receptor modulator. Preclinical studies compare its anabolic effects with other SARMs, highlighting its potential in muscle preservation and fat loss.
How Does S-23 SARM Work?
S-23 selectively binds to androgen receptors, particularly in muscle and bone tissue. This selectivity allows it to mimic the positive effects of testosterone, such as muscle growth and bone density, with the intention of reducing systemic side effects commonly seen with anabolic steroids, though clinical data is limited.
Potential Benefits:
Male Birth Control
Preclinical studies suggest that S-23 suppresses luteinizing hormone (LH) and follicle-stimulating hormone (FSH), both essential for sperm production. In animal studies, this resulted in temporary infertility, which reversed after discontinuation. {R}
Increase Female Sexual Drive
With the proper dosage it may increase sexual desire in women, particularly during menopause, due to hormonal changes. {R}
Muscle Growth:
It may promote lean muscle mass development and is commonly used during cutting cycles to preserve muscle in calorie deficits. It may also assist with fat loss by increasing metabolic activity.
Bone Density:
It has shown promise in increasing bone mineral density, potentially benefiting individuals at risk for osteoporosis or related conditions. [R]
Decreased Body Fat:
It may increase metabolic rate, contributing to fat loss and improved body composition. [R]
Other Reported Benefits:
• – Selective action on androgen receptors minimizes side effects
• – May improve endurance and stamina
• – Exhibits anabolic effects promoting muscle protein synthesis
Recommended Dosage of S-23 SARM
The recommended doses range from 10–30 mg daily, with cycles typically lasting 8–10 weeks. Beginners should start on the lower end and increase only if tolerated. However dosing should be supervised by professionals.
Reported Side Effects of S-23
Reported side effects include testosterone suppression, potential liver strain, altered cholesterol levels, and mood-related changes. Post-cycle therapy (PCT) is strongly recommended to restore hormonal balance.
Where to Buy S-23 Sarm?
PureRawz, RCDBio and BehemothLabz are the best places if you are interested in buying S23.
FAQs
Does S23 Require PCT?
Like other SARMs, in the case of S23 as well, there is a big chance that your natural testosterone levels will be lowered by the use of the drug if left untreated. Testosterone suppression is likely, so post-cycle therapy is essential to restore hormonal balancer.
Is S-23 Legal?
Legal status varies by country. In many regions, it is sold for research purposes only and not approved for human consumption.
What are the Risks?
Limited human studies exist. Potential risks include hormonal suppression, cholesterol imbalances, and liver strain. Use with medical supervision is strongly advised.
Is S-23 SARM Available in Stacks?
Yes, but stacking increases risk and complexity. Always evaluate compatibility and potential side effects when combining SARMs. Some vendors now include S-23 in products like KRAKEN and NEMESIS stacks.
