One other advantage of taking S-23 is the fact that it helps with fat reduction, in addition to, oxidization that is fat. A study that was done on rats revealed that giving them S-23 reduced the rats’ body weight percentage while increasing bone mineral density and lean muscle mass. The study also demonstrates that its properties increase appreciably, which contributes to a huge decline in body fat.

  • Testosterone Shutdown

According to customers, S-23 is the closest thing to steroids that you may buy in the SARM marketplace. This makes it distinctive and far more powerful, with side-effects that are distinct from SARMs. S-23 reduces testosterone levels to the point that some users suggest supplementing with Testosterone Replacement Therapy (TRT) to resist the subsequent deficiency. The good thing is that once you’ve finished your cycle on S-23 this side effect doesn’t last and will come to be reversed.

S-23 was shown to produce a darker urine shade, but this negative effect can be temporary and only lasts while you’re biking with S-23.


Generally, it’s suggested to take S-23 in dosages of between 0.5mg and 50mg. This is based on studies that were conducted on the SARM so far.

Yes, we understand that this is a range, but just like any SARM, S-23’s dosage depends on a range of factors, such as the result you’re seeking. That said, most bodybuilders say that an effective dose is anything between 20mg and 30mg.

If you want my advice concerning the best S-23 dosage, I’d say go with about 10 to 20mg per day. Based on experiences this is the most optimal dosage. This compound is powerful and very effective, you won’t need much more.

The half-life of all S-23 is roughly 12 hours. This means to have stable levels in the blood that twice a day you will have to dose S-23. I would suggest taking your dosage that is S-23 in the evening and once in the morning.


Yes, definitely! This should not even be a question at this time and includes standard. You will need to take steps to regain balance once you cycle with almost any SARM, not just S-23. Because the amount can lead to a whole shutdown, it’s even more important to do with S-23. That means you need to undergo a very rigorous PCT to acquire your system functioning optimally again.

In reality, some users have reported experiencing similar consequences on Winstrol & Anavar when cycling with S-23, though a study by Dr. Tony Tremendous showed the same results.

That said, taking S-23 remains much less intense as cycling with steroids such as Winstrol and Anavar, for example. Overall, S-23 has been shown to produce a lean, mean and high-performing physique that can win your contests when biking in the way.


A good deal of bodybuilders adds S-23 SARM near the end of the cycle to help them create a more challenging and educated physique that is made possible by S-23’s fat-reducing qualities. Many folks report to stack SARMs such as S-23 with LGD-4033 and MK677 for amazing lean muscle gains. Therefore, rather than starting at the start, it is often advised to add S-23 throughout the 8 months of your cycle.


Judging from the experiential and research evidence this SARM is a powerhouse that can help you gain lean muscle mass, lose body fat and create a ripped, textured body.
