S 23 is a traditional Selective Androgen Receptor Modulator (SARM) that activates the androgen receptor in skeletal muscle. It is most commonly and best used to increase stamina and strength based on its high affinity for the androgen receptor.
At a dose of 15 mg daily, S 23 is very effective at exerting the benefit of increased lean body mass, muscular strength, muscular endurance, and improved fat loss. Because it activates the androgen receptor, it does suppress the Hypothalamic-Pituitary-Testicular Axis (HPTA) and has the potential for estrogenic side effects including gynecomastia in prone individuals. An aromatase Inhibitor (AI) is beneficial for these individuals during a S 23 cycle to prevent estrogenic side effects, and a selective estrogen receptor modulator (SERM) is beneficial as part of a post cycle therapy (PCT) to prevent estradiol rebound.
Remember, training and diet are still the most important parts. Even though S23 is very strong, it won’t do anything without at least somewhat proper training and nutrition. Also, if you don’t continue to train after the cycle, you will most likely lose most of your gains.
S23 also has a powerful benefit of increasing your strength. The strength gains will also be insane and comparable to the ones you would get on a normal steroid cycle. People who use S23 report incredible strength gains. They get stronger week after week and are easily able to frequently break their PRs (personal records). According to them, it is not uncommon that they get over 50lbs on their major lifts, bench press, deadlift and squat, over the cycle. When it comes to keeping that kind of strength, take that with a grain of salt. You most likely won’t be able to keep all of the strength gains, but with proper training after the cycle, you might be able to keep most of them.
S23 promotes fat loss, not as successfully as Cardarine does, but it still does pretty well. This means that you will be able to gain muscle and lose fat at the same time. You will even be able to lose some fat when on a small caloric surplus. Along with this, people also report that they look a lot more vascular during their cycles. They also get a lot better pumps in the gym that last a lot longer. S23 will to some extent also give you better endurance. It won’t be as powerful at this as some other compounds, but it will still be noticeable. You will be able to work out for longer periods of time and won’t need to take so many breaks between sets. People also report that it gives you more stamina in the bedroom as well. This makes sense because it is also being currently researched as a “male birth control pill”.
Another thing that S23 will do is it will reduce your recovery times. The usual recovery time after a hard gym session is 72 hours. People who take S23 report that their recovery times went down to less than a day. This will allow you to workout hard more frequently and because of this, you will get better results.
