S-23 Capsules

Brief Intro

S-23 Capsules contain a potent selective androgen receptor modulator (SARM) known for its high binding affinity and tissue-selective anabolic effects. Developed by GTx, Inc., S-23 is recognized for its strong androgen receptor activation, promoting lean muscle mass, bone density, and conditioning, while minimizing androgenic side effects. It has been studied as a potential male hormonal contraceptive due to its dose-dependent suppression of spermatogenesis with reversible effects. These capsules are intended strictly for scientific research and are not for human consumption.

Intended Use

S-23 Capsules are intended strictly for laboratory research, including studies on androgen receptor activation, muscle growth, bone density enhancement, hormonal regulation, and selective anabolic responses. They are not for human or veterinary consumption. Researchers use S-23 to explore its effects on lean mass development, tissue selectivity, and potential contraceptive applications.

Packaging & Shipping

S-23 Capsules are securely packaged and shipped discreetly with tracking. Typical delivery times are 24-72 hours within the USA and up to 5 days internationally, depending on destination. Shipping fees are calculated at checkout based on location.

Legal & Compliance Disclaimer

Dosage and use

Next lvl muscle S-23 can be taken twice a day for 6 to 12 weeks. It is recommended to take this SARM up to 30 minutes before your workout and after a meal.

S-23 can be combined with other SARMs and can be used during bulking and cutting.

What are SARMs?

SARMs are Selective Androgen Receptor Modulators. Put simply, these substances can tell your cells that they need to, for example, create more muscle mass or break down more fat. Each SARM has a different effect, allowing you to achieve very targeted aesthetic and physical goals. And that without experiencing unpleasant side effects such as hair loss, acne and liver damage.
