Have you ever envisioned a pill that could promote a more balanced sharing of contraceptive responsibility between partners? Ever imagined both partners having the ability to control fertility with the likelihood of unintended pregnancies dropping to a minimum? Now imagine the same pill having the power to increase lean muscle mass and decrease unwanted body fat. Well that magic drug may have already been invented and it is known as S23 Sarm.

S23 Sarm is a selective androgen receptor modulator (SARM) that is gaining popularity for its potential applications in the field of muscle wasting, osteoporosis, and other conditions related to muscle and bone health. S23 is also currently being tested as a potential male contraceptive or male birth control pill.

GTX, Inc. developed S23, commonly referred to as S-23, which is a selective androgen receptor modulator, or SARM. Although S23 mechanism of action is still not well known, it is often compared to SR9009 Stenabolic.

S23 is known to aid muscle gain and fat loss. With effects including muscle building, fat loss, strength gain, and endurance, it is regarded as one of the most potent SARMs on the market.

Selective Androgen Receptor Modulators (SARMs):

For our new readers, SARMs are a class of compounds designed to have effects similar to anabolic steroids but with fewer side effects. They work by selectively binding to androgen receptors in the body, influencing muscle and bone tissues. Unlike traditional anabolic steroids, SARMs aim to be more selective in their action, targeting specific tissues without affecting others.

For more information on SARMs check out the detailed article on Introduction to SARM.

How Does S-23 SARM Work?

SARMs, in general, have this tendency to selectively bind to only androgen receptors. The human body typically has 47 nuclear receptors. While other compounds in the market are generic in their targeting of tissues and body receptors, S23 SARM is very selective in its targeting of AR hence making it a good option for people looking for faster muscle gain.

S23 SARM is known for its high affinity and selectivity for androgen receptors. It is believed to bind to androgen receptors in a tissue-selective manner, focusing on muscle and bone tissues.

The selective binding is intended to mimic the positive effects of androgens on muscle growth and bone density without the undesirable side effects associated with traditional steroids.

Potential Benefits:

1. Male Birth Control

S23 has shown great potential as a male contraceptive since it can block the LH and FSH hormones, which are essential for sperm development.

Studies in male rats have shown that those treated with S23 had incredibly low sperm counts, which led to complete infertility. Sperm counts returned to normal as soon as S23 was discontinued. {R}

2. Increase Female Sexual Drive

With the proper dosage, women’s sexual desire and arousal can potentially enhance considerably, which otherwise decreases throughout menopause, due to the typical reduction in sex hormones. {R}

3. Muscle Growth:

S23 SARM is studied for its potential to increase muscle mass development. S23 is often used during cutting phases or calorie deficits to help preserve lean muscle mass. It may reduce the risk of muscle loss that can occur when individuals are in a calorie deficit or undergoing intense training. [R]

S-23 is designed to selectively bind to androgen receptors in muscle tissue, promoting muscle growth without the extensive side effects associated with traditional anabolic steroids. 

4. Increased Lean Muscle Mass:

Studies on S23 SARM suggest that it may contribute to more lean muscle mass, which is desirable for individuals looking to enhance their physique or combat muscle-wasting conditions. [R]

5. Bone Density:

Research has suggested that S23 SARM might contribute to increased bone mineral density, which is crucial for overall bone health. It may have a positive impact on bone health and density. This could be particularly beneficial for individuals at risk of or suffering from conditions like osteoporosis. [R]

6. Decreased Body Fat:

Some users claim that S23 can boost fat loss and body recomposition. Therefore the drug may help increase metabolic rate and help reduce fat mass. [R]

7. Selective Binding:

One of the key advantages of SARMs including S23 is their purported selectivity in binding to androgen receptors. This selectivity is theorized to minimize the risk of unwanted side effects commonly associated with traditional steroids. {R}

8. Endurance and Stamina:

Some users and studies have suggested that S-23 may contribute to improved endurance and stamina. This could be advantageous for athletes and fitness enthusiasts.[R]

9. Potential for Therapeutic Applications:

SARMs, including S-23, have been explored for their therapeutic potential in various medical conditions such as muscle wasting disorders, frailty in the elderly, and other conditions where muscle and bone health are compromised.

10. Anabolic Effects:

S-23 among other SARMs are compounds considered to have anabolic effects on skeletal muscle cells, which means they may promote muscle growth and improved muscle protein synthesis, the effects highly desired among bodybuilders.


What is the Recommended dosage of S23 SARM?

The recommended dosage of S23 varies depending on the user’s experience level. For beginners, it is recommended to start with 10mg per day and gradually increase the dosage to 20-30mg per day. The cycle length should not exceed 8-10 weeks

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. However, there is no need to worry at all as you only have to make sure that you take effective post-cycle therapy to avoid experiencing any negative consequences from low testosterone once your cycle is over.

What are the Side Effects of S23?

As with any investigational compound, the potential side effects of S-23 are not yet fully understood. However, researchers and users have reported some side effects that may include hormonal imbalances, suppression of natural testosterone production, and potential effects on lipid profiles.

What is its Legal Status?

The legal status of S-23 varies by country. In some places, SARMs are classified as research chemicals, while in others, they might be subject to regulations.

What are the Limitations and Caution?

S-23 has primarily been studied in clinical trials using animal models. Due to the limited human studies and potential side effects, caution is advised when considering using S-23 or any other SARM.

Individuals should be aware that self-administration of SARMs without medical supervision may carry risks.
