Buy S23 SARM Powder Online

S23 SARM is a nonsteroidal selective androgen receptor modulator (SARM) known for its potency, closely resembling that of anabolic steroids. It’s a subject of interest for its potential impact on muscle growth, bone density, fat loss, sex drive, and use as a male contraceptive.

Pharmacological Properties of S23 SARM

S23 has an oral bioavailability of approximately 96%, reaching peak levels around 4 hours, with a half-life of 11.9 hours. It mimics the action of testosterone in muscles and bones, potentially promoting protein synthesis and muscle growth.

Potential Applications of S23

Male Contraception

S23 has been studied as a potential male contraceptive agent in rats, causing temporary interruption in fertility, although the effect on human fertility is unknown.

Muscle Mass and Fat Loss

S23 may increase lean muscle mass and decrease body fat in a quantity-dependent manner, and even outcompete the catabolic effects of some compounds . It also prevented muscle loss from glucocorticoids in another study.

Bone Health

Rat models have shown an increase in bone mineral density with S23 SARM administration, with both low and high quantities equally effective.

Sexual Motivation

S23 has demonstrated significant effects on sexual activity and drive, particularly in postmenopausal female rats, without affecting uterine growth.

Safety Concerns

S23 has never been clinically tested on humans, leaving its safety profile unestablished. Concerns include potential liver damage, effects on fertility, and natural testosterone levels.

S23 SARM shows exciting potential in various applications, from muscle development to contraception. Its high oral bioavailability, potent anabolic effects, and unique impacts on sexual motivation distinguish it.

However, the lack of human testing raises questions about its safety and efficacy. Continued research is essential to fully understand the risks and benefits of S23 SARM.

SARM S23 exerts its effects by binding to androgen receptors, eliciting tissue-specific anabolic responses.

While rat studies suggest a notable and temporary reduction in sperm count, it is important to note that S23 lacks sufficient clinical data to be reliably employed as a male contraceptive at present.

Available data indicates that S23 may lead to a temporary but notable reduction in natural testosterone levels in males.

Why buy S23 from Sports Technology Labs?
