S23 SARM Review: The Strongest SARM For insane Muscle Growth

Today we will be reviewing one of the strongest SARMs on the market called S23. It’s S23 SARM just like LGD-4033 and RAD-140 and known for its powerful effects on the muscle tissue.

It has been designed and tested by a pharmaceutical company called GTX. These SARMs have the ability to selectively bind to the androgen receptor just like with AAS(Anabolic Androgenic Steroids) or prohormones. 

These products are quite new and are only available as research chemicals.

Guys, I am going, to be honest, I am truly amazed by its effects and I advise you to read the whole S23 review before purchasing. 

What Is S23 & How Does it Work?

S23 is a selective androgen receptor modulator produced by the well known pharmaceutical company GTX and is still investigated to date. Researchers found out that this SARM had the ability to increase lean muscle mass and burn fat. 

As you might already know, there are many other SARMs just like S23, for example, RAD-140 (Testolone), MK-2866 (Ostarine), and LGD-4033 (Ligandrol). They all work the same but not all of them have the same effects.

S23 works by binding itself with the androgen receptors and is marked as non-steroidal. It’s currently on the ban list of WADA, and you are not allowed to use if it in most sports. 

Many users of S23 noticed that it has fewer side-effects and was well tolerated for a long period of time. 

4 S23 SARM Benefits

1.  Muscle Mass

After using s23 for a period of at least 6 weeks, users noticed an increase in lean muscle mass. A study on the effects is S23 showed a significant increase in muscle mass and even a loss in body fat. 

2. Fat Loss

Next to its potent effects on muscle tissue, most users also noticed that it made there muscle ‘full’ and ‘hard’. It made them feel that it had the same effects as Anavar or winstrol. 

Also, multiple studies found out that it had a positive effect on the fat-burning process. 

3. Power Output & Strength

This SARM has the ability to make you very strong and lift more of the heavyweights than normal. The only SARM that could be close to the effects of S23 is RAD-140, which is also known for its strength and lean muscle gains.

4. No Water Retention

Users who took this compound experienced close to nonwater retention and only dry muscle gains. Some people even believe that this could be the next ‘Trenbolone’ SARM.

S23 SARM – Are There Any Side-Effects?

It’s one of the most powerful SARM on the market and has been used quite a lot. While it’s something that has been tolerated quite well, there are also some side-effects that are worth mentioning.

Testosterone Suppression

S23 is a SARM that was originally researched as being useful as a Hormonal Male Contraception. This means that your Testosterone will get shut down quite hard and quick.

It’s therefore advised to at least run a proper post cycle therapy like Rebirth PCT. You will recover quite fast after the usage of S23. However, most users experienced that this SARM is really strong and could take at least 8 weeks of PCT.

Hair Loss

As mentioned earlier, this will suppress your natural testosterone meaning your hormone levels will be elevated a lot. Hormonal imbalance can result in hair loss for men that are already prone to hair loss. 


Some users also experienced an acne outbreak after the usage of S23. This was only when they were on a cycle and it went away pretty quick. This is also the result of the hormonal imbalance like hair loss.

As you can see, there are quite some side-effects, however, keep in mind that only a small percentage of people notice this. It’s also dose depending on what you can expect in terms of adverse effects.

What Can You Expect From an S23 SARM Cycle & Is It Worth It?

You can expect to gain at least a couple of LBS of lean muscle mass depending on your cycle length, dosage, and your genes.

And I am not talking about water weight or glycogen stores. 

No, I’m talking real muscle that you will notice immediately. 

So, how should I use this SARM, and for how long?

Well, on average, a cycle length between 6 and 8 weeks would be sufficient. Most users take around 10-20mg daily for optimal muscle gains.

There is really on reason to go any higher than 20mg. 

However, some people like to experiment with it, and I personally have seen people use over 100mg a day.

They got terrible aggressive side effects, and you have to remember that it will suppress your natural testosterone.

Take a look at the video down below, these people took a VERY high dosage of S-23, and I would not recommend going that high.

So, is it worth your time and money using S23?

Well, if you are looking for something that will give you lean muscle gains. 

Then yes, S23 is definitely something for you. But don’t run a SARMs stack with it.

However, if you are someone that doesn’t like the side effects mentioned above then you should take a look at something else.

For example, legal steroids would a great alternative to S-23.

Also a quick note: This SARM is definitely not something you would want to take if you are a woman. 

It’s best to take more women-friendly SARMs like Ostarine or Andarine.

Do You Need A Post Cycle Therapy?

Let me put it this way. If you want to feel like shit, than no, you do not need a post cycle therapy.

If you want to recover from low testosterone from taking S23, then you should take a proper PCT supplement.

Most people who took S23 all experienced significant testosterone suppression. There is literally no other SARM that has so much suppression.

If you are on TRT or HRT, then this should not be an issue.

But, if you are a nature lifter, then you will feel suppressed.

Meaning you will be tired, weak, and something can’t even get a boner. Not even a male enhancement pill will help you with that.

So guys, please use a good SARMs PCT Supplement.

My recommendation would be Rebirth PCT by Huge Nutrition, that product is everything you need to recover from a S23 SARM cycle properly. 

How Does S23 Compare To Other SARMs And Steroids?

S23 is absolutely useful in terms of muscle size, strength, and recovery.

But how would something like this compare to other SARMs or even Steroids?

Well, S23 could be classified as SARM for more experienced lifters and users. It’s definitely not a beginning SARM like Ostarine or LGD-4033. 

I would say that S23 would beat LGD-4033 and Ostarine in terms of muscle gains.

However, if you take a look at the side-effects, then using something like LGD-4033 would be way safer and with fewer side effects.

It depends on your own opinion if it’s worth taking or not. As said before, if you are someone that is currently on TRT, then it could be worth it.

Can you compare S23 to a steroid-like Testosterone in terms of size and strength?

No, Testosterone will beat S23 any day. 

However, S23 is more convenient since you can take it orally, and it does not need to be injected.

Conclusion: Would I Recommend S23 SARM?

The research on this compound is very promising and there are many benefits you could experience. 

However, the big question is: Do the benefits outweigh the side effects?

In my opinion, yes they do outweigh the benefits and I would recommend using this SARM.

Keep in mind that you should ALWAYS do a post cycle therapy after running a cycle. 

Where to buy S23 SARM and where is the S23 offered for sale

A great place to get the S4 SARM for a good price is Chemyo

They’re known as one of the biggest and most trusted vendors for these types of compounds.

You will find that they’re slightly more expensive compared to other places, but they have high purity S-23, which is very important.

We’ve used it before and have been very satisfied with both the product quality and service.

We will be happy to hear your thoughts
