Stenabolic (SR9009) Guide: Results, Cycles, Dosage, & More!
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 (Stenabolic)?
Despite many misguided people grouping SR9009 together with SARMs, Stenabolic is not a SARM—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 Stenabolic is currently not approved for human use, this hasn’t stopped many endurance runners from taking it recreationally.
SR9009 vs. SARMs
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]
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.
How Does SR-9009 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 one of the reasons why SR9009 is known for increasing overall energy and endurance.
By increasing the amount of mitochondria in the skeletal muscles, Stenabolic enables users to attain supraphysiological endurance levels.
In fact, one study found that lab mice treated with SR9009 could run for much farther distances, and for much longer periods of time. [R]
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.
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, SR9009 is by far the endurance athlete’s best friend.
SR9009 (Stenabolic) 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 one 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.
Dosage & Cycle Guidelines
Because no human trials have been conducted with SR-9009 to date, it’s difficult to ascertain a good dosage 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 Stenabolic 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 20 mg per day, would be the equivalent of one full dropper of the SR9009 from Science Bio.
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 – 10 mg per day||SR9009 – 20 mg per day|
|Ligandrol – 20 mg per day||Ostarine – 25 mg per day|
|YK11 – 10 mg per day||Andarine – 50 mg per day|
Because Stenabolic is naturally best for weight loss, most users choose to combine it with SARMs that are good for cutting, 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.
Potential 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 (S9009):
- Difficulty Sleeping
- Moderate Nausea
- Mild Headaches
Most users who log their Stenabolic 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 endurance enhancing compound which many body builders choose to take recreationally.
Note that Stenabolic 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 Science Bio.
Every batch of their SARMs and research chemicals are 3rd party verified, and if you use the code “nanotech” you’ll get 10% 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.
