S23 SARM Guide: Benefits, Dosage, & More (Updated 2020)
Chances are you’ve heard of SARMs before, but many people haven’t heard of a SARM called S23—and it’s a shame, it really is.
S23 is one of the more powerful SARMs on the market, which some recreational users claim can even rival RAD 140 and Ligandrol.
Is it true, though? Can the S23 SARM really transform your physique in just one cycle? Or is it just a bunch of bro science served up by marketers?
In this article we’ll cover everything you need to know, A-Z, about S23, ranging from side effects, to the benefits, dosage, clinical studies, and more!
What is S23?
S23 belongs to a class of research chemicals known as SARMs, which stands for selective androgen receptor modulators. These are highly anabolic compounds that signal your body to build muscle at a steroid-like rate.
SARMs have been around for decades now, but S23 in particular was created by modifying a SARM call C-6, and making it more effective. [R]
In short, S23 is a powerful anabolic research chemical that many recreational users are taking to rapidly increase lean muscle mass.
But, is it safe? What are the side effects? Let’s take a look at what the clinical research has to say about this SARM, and get a bit more in-depth.
Overview of Pros & Cons
Before we get into the nitty-gritty research studies, we’d like to offer our readers (that’s you) a brief look at the pros and cons of this SARM.
The benefits of S23 include:
- Increased Muscle Mass
- Accelerated Fat Loss
- Added Bone Mineral Density
- Potential for Male Birth Control
- No “Night Vision” Side Effects (Like S4)
- Faster Recovery Time Post-Workout
Potential drawbacks of S23 include:
- Can Have Some Negative Side Effects
- Potentially Unknown Long Term Effects
- Not Approved For Human Use by the FDA (Yet)
- More Clinical Studies Should Be Done With S23
While S23 is generally considered to be a safe SARM by most recreational users, it’s important to note that more research should be done on this.
Even so, S23 as a SARM offers body builders tremendous promise when it comes to accelerating muscle gain and fat loss, with minimal side effects.
Is S23 Legal?
When it comes to SARMs, which includes S23, they’re strictly outlawed for athletic use in the Olympics by the World Anti-Doping Agency.
The United States Anti-Doping Agency, or USADA for short, has also banned SARMs from competition—so if you’re an athlete who is thinking of using SARMs, then think again, because you could get disqualified for it.
With this being said, SARMs are still 100% legal to purchase.
Tons of recreational users order SARMs online and choose to use them for their own personal needs, although this still hasn’t been FDA approved.
How to Get S23
As we’ve covered in previous articles, there’s a ton of fake SARMs vendors out there, and the FDA has warned about companies like this in the past.
Here at Nanotech, we keep a log of SARMs vendors we consider to be reliable, with high quality products, and we write reviews on all of them.
One of our top vendors, and the one we recommend the most, is called Science Bio—in fact, we wrote a full review on them that you can read.
How Does S23 Work?
S23 has a half life of roughly 11.9 hours (in lab rats), which is in line with most SARMs, which are generally fast acting and produce fast results. [R]
In other words, S23 begins working shortly after ingestion, binding to androgen receptors, and signaling your body to rapidly build muscle.
It should come as no surprise then, that many recreational users are able to pack on 10-15 pounds of muscle from a single S23 SARM cycle.
Benefits of S23
S23, which is available for purchase here, has a load of benefits for bodybuilders, which is why it’s such a popular SARM these days.
The benefits of S23 include:
- Accelerated Muscle Growth
- Increased Power & Strength
- Higher Bone Mineral Density
- Rapid Fat Loss (Great For Cutting)
S23 has been shown to have these benefits many times in clinical studies, and recreational users have confirmed these benefits as well.
We currently have a SARMs before and after article, which is a compilation of all the results that users have gotten from using different SARMs—so we recommend you read that if you want to learn more.
That being said, most users report gaining something like 10-15 pounds of muscle mass from a single 2-3 month cycle of S23, followed by a PCT.
S23 is primarily a cutting SARM however, and is known for creating the “hard and dry” look that tons of body builders love when cutting.
So, if you’re looking to get your muscles to “pop” and look really nice, hard, dry, and shredded, then consider checking out S23 as a potential option.
Dosage & Cycle Guidelines
Because there have been no clinical studies conducted on humans to date, there is no established dosage for humans (although there is for lab rats).
Generally speaking however, most recreational users agree that taking roughly 10-25 mg per day of S23 is going to be the sweet spot.
Here are the S23 dosage guidelines:
- Beginner Dose: 10 mg per day
- Intermediate Dose: 15 mg per day
- Advanced Dose: 25 mg per day
While some users have reported having little to no side effects on dosages as high as 30 mg or more, most body builders agree that 25 mg is good.
SARMs are frequently dosed in mg/ml as well, so a 25 mg dose of S23 would be equivalent to taking one full dropper of the S23 from Science Bio.
S23 Bulking & Cutting Stacks
S23 is generally taken for cutting reasons, although as with many other SARMs, it can still be used on a bulking cycle to help users stay lean.
|Sample Bulking Stack||Sample Cutting Stack|
|S23 – 15 mg per day||S23 – 25 mg per day|
|Ligandrol – 20 mg per day||Ostarine – 25 mg per day|
|MK 677 – 25 mg per day||Cardarine – 10 mg per day|
S23 Side Effects
Most recreational users who try S23 report that the side effects are only temporary, although more research does need to be done to confirm this.
That being said, S23 is, in fact, one of the most suppressive SARMs—so suppressive, it’s being considered as a potential male contraceptive.
Here are some potential S-23 side effects:
- Increased Aggression
- Facial & Back Acne
- Faster Hair Loss
- Testosterone Suppression
There is also an extremely small chance of gynecomastia, however the odds of this can be lowered by doing a good on cycle and post cycle therapy.
We definitely recommend following a post cycle therapy (PCT) after an S23 cycle, as it’s one of the most suppressive SARMs. Do a PCT to be safe.
In summary, S23 is a potent SARM that can be used to preserve lean muscle mass on a cutting cycle, or to help keep fat off during a bulking cycle.
It’s generally considered to be one of the strongest SARMs, particularly when it comes to mimicking the effects of Winstrol or Anavar.
If you want to purchase 3rd party tested, 99.5% pure S23, we recommend you go through a high quality vendor like Science Bio.
All of their SARMs are tested for purity, and best of all, if you use the code “nanotech” you can save yourself 10% off any SARMs you wish to buy!
