While many people group Stenabolic, or SR9009, into the SARMs category, it’s actually not a SARM—it’s a ReV-Erba receptor agonist.
Regardless, it is often grouped with SARMs, because they’re both research chemicals that have profound effects that body builders find useful.
Using a compound like SR 9009, many recreational users report rapid weight loss, decreased cholesterol, and enhanced endurance levels.
In this article, we will cover the known side effects, dosages, cycles, and more, so that the readers of this site can get accurate facts and information.
What is SR9009?

Despite many misguided people grouping SR9009 together with SARMs, Stenabolic is not a selective androgen receptor modulator—rather, it is a PPARδ receptor agonist.
Stenabolic (SR9009) was initially developed by Professor Thomas Burris at the Scripps Research Institute, as potential treatment for people suffering from cardiovascular and metabolic diseases. [R]
It didn’t take long for body builders to realize that healthy individuals could take SR9009 to drastically enhance endurance, however.
And while SR9009 is currently not approved for human use, this hasn’t stopped many endurance runners from taking it recreationally.
Before we get into the results, dosage, benefits, and where to buy this compound, we want to first offer a brief overview of SR9009.
Overall, SR9009 is a phenomenal compound for fat loss in particular, with many people losing upwards of 10-15 pounds of fat in just a single cycle.
Benefits of SR-9009:
- Accelerate Fat Loss
- Retain Lean Muscle Mass
- Increase Energy Levels
- Improve Muscle Stamina
- Enhance Exercise Endurance
- Doesn’t Suppress Testosterone
Drawbacks of SR-9009:
- Not Great For Bulking
- Potential Health Side Effects
Overall, SR9009 is a phenomenal compound for losing fat and is great for any sort of cutting cycle. You don’t even need a PCT for it, either.
One of the biggest questions people have when considering buying SR-9009 is whether or not it’s legal. Thankfully, Stenabolic is currently classified as a research chemical, and is 100% legal to buy and sell online.
Of course, that doesn’t mean you won’t be tested for it if you’re an athlete. Both the World Anti-Doping Agency (WADA) and the United States Anti-Doping Agency (USADA) have banned the use of Stenabolic from the competition. [R]
If you’re a high-level athlete, you may be tested for SR-9009 before competition, but most people won’t have to worry about this. Right now, only Olympic-level and professional level athletes are tested, not collegiate or high school level athletes.

Our #1 recommended source for all research chemicals is currently Pure Rawz. We’ve been using them for years and we love them—and best of all, they gave us a code you can use, too. Just use the code “MD15” for 15% off.
How Does SR9009 Work?
Similar to Cardarine (GW-501516), Stenabolic works by binding to the ReV-Erba receptor, which signals the body to increase mitochondria count.
And if you recall anything from your biology class, it’s probably that mitochondria is the powerhouse of the cell. This is a big reason why SR9009 is known for increasing overall energy and endurance.
By increasing the amount of mitochondria in the skeletal muscles, SR9009 enables users to attain supraphysiological endurance levels.
In fact, this particular study found that lab mice treated with SR9009 could run for much farther distances, and for much longer periods of time. [R]
Is It A SARM?
Contrary to popular belief, SR9009 is not actually a SARM—rather, it’s a compound which is classified as a ReV-Erba Receptor Agonist. [R]
Rev-Erba are proteins that regulate circadian rhythm (the body’s internal 24-hour clock). As a result, they regulate glucose metabolism, fat burning, and skeletal muscle mass. Their increased activity in the body also leads to increased stamina. [R] [R]
SR9009 is still sold by most SARMs vendors however, as the drug is currently in the same legal classification as SARMs (research chemicals).
In other words, even though SR9009 hasn’t been approved by the FDA (yet), it’s still 100% legal to buy, which bodybuilders are doing in droves.
Stenabolic Vs Cardarine
Both these compounds are fat burners.
Stenabolic, as stated above, is a Rev-Erba receptor agonist. Animal studies have shown that it could decrease body weight by burning fat. SR9009 could also lower blood glucose levels and enhance endurance or exercise performance.
Cardarine is a well-known PPAR delta receptor agonist, mistaken as a SARM by most people. It could also lower body fat, increase endurance and decrease blood cholesterol levels. Cardarine could also increase your calorie metabolism (it could make you burn more calories).
Given their similar benefits, stacking Stenabolic and Cardarine will make for a killer fat-burning stack. 10 – 20 mg of both might be enough to hit your cutting goals.
To date, there have been no human trials conducted with Stenabolic, so many of these benefits haven’t yet been observed in human beings.
That being said, many users report drastic increases in endurance and energy levels, both for cardiovascular and muscular workouts.
Here are some benefits of Stenabolic (SR9009):
- Rapid Fat Loss
- Improved Cholesterol
- Enhanced Endurance
- Decreased Inflammation
- Higher Energy Levels
In addition to these benefits, Stenabolic also doesn’t suppress natural testosterone levels, like SARMs such as RAD 140 or Ligandrol do.
Rapidly Shred Body Fat
One of the biggest health benefits of SR9009 is that it helps users to rapidly lose weight. In fact, this is perhaps the primary benefit of SR9009.
Similar to Cardarine, SR9009 is a ReV-Erba Agonist, which quickly acts in the body and begins promoting fat loss and cholesterol improvements.
While the long term health effects of SR9009 aren’t very well studied, one thing is clear: this is one of the strongest fat loss supplements out there.
Preserved Muscle Mass
Studies have shown that Stenabolic preserves muscle mass via its regulation of the circadian rhythm or the body’s internal 24-hour clock.
Circadian rhythm has been proven to be critical for the maintenance and growth of skeletal muscle mass, influencing a remarkable 17% of all muscle genes observed. [R]
That means that weight lifters, bodybuilders, and athletes can count on SR9009 to help them retain muscle growth already achieved while also burning fat cells.
Another major benefit of SR9009 is that it enhances endurance to a very large extent, by allowing the muscles to use energy more efficiently.
In fact, one study conducted on lab mice found that this compound led to significantly higher levels of endurance across the board. [R]
So, while it may not grow your muscles as effectively as a drug like RAD 140 or Ligandrol, SR-9009 is by far the endurance athlete’s best friend.
Higher Energy Levels
In addition to the fat loss effects, muscle retention effects, and stamina enhancing effects of SR9009, another great benefit is the energy boost.
When I first tried SR9009, I felt like I could keep going for hours on the treadmill—it was within a week of taking it, too. So, it acts very fast.
More energy means you can also get better results in the gym. You can burn fat faster, build muscle faster, and it will even enhance your productivity.
Another great benefit of this drug is that it has been clinically proven to improve heart health by lowering LDL cholesterol and leaving HDL cholesterol alone. This is especially helpful for anyone using anabolic steroids, which can tend to throw your cholesterol balance out of whack.
In fact, in a study published in the prestigious Nature journal, it was found that mice treated with SR-9009 for only just 7 days, showed reduced triglyceride levels, as well as reduced total cholesterol levels. [R]
Another study, published in Volume 131 of the Biochemical Pharmacology journal, found that after undergoing 8 weeks of treatment with SR9009, both triglycerides and LDL cholesterol were lowered in mice. [R]
Stenabolic SR9009 Results
What kind of results can you expect from an SR9009 cycle? Well, the truth is that the results will vary depending on the dosage and cycle length.
That being said, many users who use SR9009 for weight loss report losing 10-15 pounds from just a single 8-12 week cycle of Stenabolic.
Most cycle logs and user reports suggest that you can expect to lose 10-15 pounds and drastically increase your endurance from one cycle.
Again, remember that SR9009 has not been approved by the FDA for human use, either—so many of these results are anecdotal from body builders.
SR9009 Dosage & Cycle Guidelines
Because no human trials have been conducted with SR9009 to date, it’s difficult to ascertain a good dose for bodybuilding and endurance.
That being said, the general consensus amongst body builders is that 10-40 mg is usually the best dosage to get good results with minimal side effects.
Here are the best SR9009 dosages:
- Beginner: 10 mg per day
- Intermediate: 20 mg per day
- Advanced: 40 mg per day
The effects of SR9009 are dose dependent, meaning that the more you take, the more benefits and also side effects you will likely experience.
An intermediate cycle, for example, which is 20mg/day, would be the equivalent of one full dropper of the SR9009 for sale from PureRawz.
Bulking & Cutting Stacks
Some users choose to take multiple SARMs at once, to enhance the effects they experience, build more muscle, and lose more fat.
|Sample Bulking Cycle||Sample Cutting Cycle|
|SR9009 – 10mg/day||SR9009 – 20mg/day|
|Ligandrol – 20mg/day||Ostarine – 25mg/day|
|YK11 – 10mg/day||Andarine – 50mg/day|
Because SR9009 is naturally best for weight loss, most users choose to combine it with SARMs that are good for fat loss, such as Ostarine.
That being said, it can also be used on a bulking cycle, to prevent too much fat from being gained while building muscle, even in a caloric surplus.
Does Stenabolic Require PCT?
Another great benefit of SR9009 is that no post cycle therapy is required, since it doesn’t affect your testosterone levels in the slightest (like SARMs).
This means that you can get all the fat loss benefits of this compound, and even build up some muscle in the process, with no test suppression at all.
You also won’t have to get blood work done on cycle to check hormone levels, since it doesn’t lower testosterone. You may want to get your blood lipids and cholesterol checked on cycle, though. Seek professional medical advice to know more.
SR9009 Side Effects
Because SR9009 has never been tested in human trials, the long term side effects aren’t known very well—more research should be done on this.
We do, however, have many reports from body building forums and user cycle logs, explaining the short term side effects they experienced.
Here are some potential side effects of Stenabolic (SR9009):
- Difficulty Sleeping
- Moderate Nausea
- Mild Headaches
Most users who log their SR-9009 experience online claim to experience no side effects, however this hasn’t been proven or disproven in studies.
In conclusion, SR9009 is a powerful fat loss agent and an endurance-enhancing compound which many body builders choose to take recreationally.
Note that SR9009 has not been approved by the FDA for human use, although it is legal to purchase online for research purposes.
If you want to buy 3rd party tested, 99% pure Stenabolic from a reputable vendor, we recommend you get it from PureRawz.
Every batch of their SARMs and research chemicals are 3rd party verified, and if you use the code “MD15” you’ll get 15% off your entire order.
❓ Is Stenabolic Good For Bodybuilding?
Stenabolic (SR-9009) is a great compound for burning fat and enhancing endurance, which is why bodybuilders often use it for cutting, or during an "on season" before a show. Many bodybuilders report being able to lose 10-15 pounds from just one cycle of Stenabolic.
❓ How Does Stenabolic Work in the Body?
Stenabolic is a PPAR Delta Receptor Agonist, similar to Cardarine, which means that shortly after ingestion it binds to PPAR Delta receptors. From here, it signals your body to increase its' metabolism and switch over to ketosis, which helps to drastically accelerate fat loss.
❓ What is Stenabolic Used For?
Stenabolic (SR 9009) is most commonly used for fat loss and increasing endurance. In fact, many marathon runners and anecdotal users have reported being able to slice off over an hour on their marathon times from simply taking a cycle of Stenabolic.
❓ What's The Best Stenabolic Dosage to Take?
While dosages range from 10-40mg per day, most medical professionals recommend that beginners start by taking 10mg per day to assess their tolerance. For fat loss in bodybuilding, 10-20mg per day is typically the best Stenabolic dosage.
❓ Does Stenabolic Require A PCT?
No. Since Stenabolic (SR9009) is not a SARM (Selective Androgen Receptor Modulator), a cycle of Stenabolic does not require a post cycle therapy, or PCT for short. It does not suppress testosterone production, and therefore does not require a Nolvadex or Clomid PCT.
Read your review and decided to take the plunge to try this out. I decided to go with bio.science because of multiple great reviews. Your dosing/cycling guidelines you had listed said that the dropper that bio sends is equivalent to 20mg (1 full dropper = 20mg). The dropper they sent me is measured in ml and is a total of just 1 ml. Doing the math, 1ml is just 1 gram, so I’m having a hard time understanding the 1 dropper = 20 part. When you researched, perhaps you had a larger capacity dropper? Or they sent me the wrong dropper… or there’s something else to the calculation I’m missing? Hoping to hear how you got your measurement figured.
No, no. 1ml is one full dropper. ML is a unit of liquid, grams is a unit of WEIGHT. So in other words, one full dropper, which is 1ml, contains 20mg of Stenabolic in it.
So does this then mean that for a beginner taking 10mg per day, it should only be 1/4 of a dropper 2x per day to get the correct dosage?
And then 1/4 of a dropper 4x per day to get 20mg when they work up to intermediate?
