History of Stenabolic

Professor Thomas Burris of the Scripps Research Institute developed SR9009, better known as Stenabolic. Though SR9009 is associated with SARMs, it is actually a Rev-erbα agonist drug.

“Rev-erbα who?”, you might be asking. Well, this is a protein most commonly found in the liver, skeletal muscle, the brain, and the adipose tissue (body fat). It participates in the circadian regulation of these tissues. In other words, it has to do with one’s circadian rhythm, better known as the biological clock.

Researchers found out that the compounds found in Stenabolic affected this protein. As a result, animal test subjects showed an increase in endurance and a decrease in obesity. Mice treated with the drug had a 50 percent increase in running capacity, measured by both time and distance.

To quote Burris: “The animals actually get muscles like an athlete who has been training.” Not only that, but the rodents developed muscles similar to those of a seasoned athlete in a very short time.

Unfortunately, the drug was never approved by the FDA. But we humans are known for our fondness of forbidden fruits. And so, athletes were quick to get their hands on SR9009 .

How SR9009 Works

The phrase ‘exercise in a bottle’ may sound a bit over the top. However, a study revealed that SR9009 caused a steep reduction in animal obesity. As we mentioned earlier, it actually alters the core biological clock. This clock synchronizes the rhythm of the body’s activity all day and night. Basically, it can be compared to our phones and computers automatically adjusting to time zones and DST.

Now, Rev-erbα is a protein that controls glucose levels and lipid metabolism in our liver. It also stores fat cells and removes dead or dying cells during inflammation. The reason Stenabolic is called an agonist is that it enhances the activity of Rev-erbα.

It had the following effects when tried on animals and cells:

  • SR9009 caused an increase in overall oxygen consumption.
  • SR9009 caused a decrease in the production of new fat cells in the liver.
  • It lowered the production of bile acids and cholesterol in the liver.
  • It caused muscle mitochondria to rise in number.
  • It increased fatty acid and glucose use in muscles.
  • SR9009 decreased the storage of fat.

This study, Injecting mice with the drug for 7 days resulted in them losing fat mass, therefore losing weight. However, this did not affect their food intake. Mice that were genetically obese stopped gaining weight after 12 days without any change in their tolerance to insulin or the amount of glucose.

Similarly, mice treated with SR9009 between 7 and 10 days had their total cholesterol reduced. On the other hand, mice given SR9009 for 30 days showed increased endurance, as previously mentioned.

The inflammatory molecules found in the nerve cells of the rats also decreased in production because of SR9009. Also, it resulted in improved heart function while reducing heart size and weight in mice with surgically induced heart growth.

SR9009 also changed the sleeping schedule of mice. Oddly enough, they were more active during the day, having had a less deep sleep. This means that SR9009 may help you maintain your wakefulness. Now, this is some good news for people doing shift work or suffering from jet lag.

Finally, SR9009 decreased the anxiety-like behavior of said mice, showcasing the effects equal to those of Bromazepam or related benzodiazepines.

How Can Stenabolic Help You?

By now, you are probably thinking it was about time to stop with the mice’s facts. So let us shift the focus to you, the athlete.


So far, you are probably relishing the idea that a substance like this even exists. A drug that turns you into a seasoned athlete in a short time is nothing but good news. And if you are already in great shape, just imagine all the effects you can achieve.

Now, as you may know, many athletes use stimulants before working out. One thing you may not be aware of is that they actually hurt you more than they help you.

The idea behind doing cardio is, of course, increasing your heart rate and maximizing your capacity. If you are struggling with cardio, your heart rate will skyrocket if you try sprinting. Let us take a 5-minute, 800-meter sprint as an example. The sprint may leave beginners winded and panting. On the other hand, experienced runners can go far without any problems.

Using traditional pre-workout stimulants does not do much to help. In fact, the stimulants will not help you at all. After using SR9009 , you are much more likely to reach 90% of your heart rate. This means that stimulants are counter-effective. In contrast to stimulants, Stenabolic will not get you winded so fast. SR9009 will give you room to push harder, as you might only go up to 75% of your maximum heart rate.

Fat loss

Regardless of your current weight, using Stenabolic can help you cut down on body fat. If you are trying to lose weight, opt-out the fat burners. This is because they do nothing but strain your body and negatively affect your sleep and heart health.

However, Stenabolic works safely because SR9009  is not a harsh drug or stimulant. Study subjects affected by Stenabolic burned fat even while resting. However, when they did exercise, the fat loss was extremely sped up.

As we’ve mentioned earlier, the Rev-erbα protein controls lipid metabolism in the liver. Stenabolic gives it a little push, resulting in an increased metabolic rate. As the number of mitochondria rises, the body is forced to burn away stored fat.

Improved Cholesterol Levels

We have to quote Billy Mays on this one. “But wait, there’s more!”

Stenabolic can also help those suffering from obesity. SR9009 will help improve their cholesterol levels and get rid of redundant glucose in their muscles.

As a result, the body will be burning fat much more quickly, whether it is during exercise or after. Remember those genetically obese mice we mentioned? Well, you can achieve a similar effect. This means your workouts will be much more effective.

User Experiences

As a performance enhancer, Stenabolic has met good to mixed reviews from users. While some reported improved endurance, others stated that its benefits were limited or non-existent. The suggested repeated dosage (which we will cover below) makes it bothersome to use.

Here are some user comments on the effects of Stenabolic:

  • “I immediately felt the effects! I felt more alert and this increased my ability to stay active during the day. However, I did get insomnia, but that was the only side effect of SR9009 I’ve felt so far.”
  • “I’ve been a strongman for years. Because of this, I used to suffer through pain and inflammation every time I exercised. Stenabolic helped me go the extra mile during workouts while making the inflammation easier to bear.”
  • “Regardless of what I tried to lower my blood pressure, my efforts were in vain. That’s when a friend of mine recommended Stenabolic. I could not believe how fast it had improved my lipid profile!”
  • “I’ve used it a couple of times. I must say my stamina and overall energy got a pretty good boost.“
  • “I would recommend Stenabolic to people who are into CrossFit and heavy lifting. Now I feel as if my energy and stamina are never going to run out.”
  • “My weight dropped by 17 pounds in less than three months. I can say the same thing for my waist size, as I’ve gone down by three sizes. All in all, Stenabolic is now my favorite compound for fat loss.”
  • “Using Stenabolic feels completely different compared to other stimulants out there. Plus, my endurance has increased significantly since I started using SR9009.”
  • Being a long-distance runner, it was hard for me to break my 20-minute record on my 5K runs. The same goes for breaking my 1:40 mark during half marathons. Having been stuck for two years, I finally tried Stenabolic, and it helped me set new personal records, even though I am 40 years old.”
  • “I didn’t really feel the effects that much.”


On an unrelated note, SR9009 can also help you increase endurance in the bedroom.

One user went to say: “Now I am a machine in the bedroom according to my wife. Even after reaching an orgasm, I can keep doing it. I can’t describe how much we both love SR9009”

SR9009 Dosage and Use

While no human dosage has been established so far, we’ve consulted a few bodybuilding forums in our search for suggestions.

The recommended dose was 20–30mg a day. Furthermore, there were users who expanded this bracket to 10–40mg. Bear in mind that the dosage also depends on how your body reacts to the drug and what your fitness goals are.

We recommend that you cycle SR9009 for 8 weeks on and then 8 weeks off to avoid building a tolerance to it. However, try not to exceed the 12-week usage. It is important to take weeks off.

You should know that Stenabolic has a short half-life, about four hours. This means your daily dosage has to be spaced out throughout the day. For example, if you are using 20 mg per day, use 5mg every 4 hours or so.

Those who find this bothersome can also use it 1–2 hours before any physical activity. This includes cardio, sex, or weight training. To some users, this makes way more sense than spacing it out throughout the day. Also, SR9009 has a sharp increase in active life within two hours of taking it, quickly leaving the system thereafter.

Stenabolic blends in perfectly with one’s existing stack or steroid cycle. This is because it is a non-hormonal compound. SR9009 will not shut you down or break up into estrogen that may cause gynecomastia (breast development).

Stacking with SARMs

As for endurance, one of the best stacks is Stenabolic + 10mg a day of Ligandrol Anabolicum (LGD 4033). It is debated whether SR9009 should be used with Cardarine (GW501506). This is because they both compete for the same receptors.

According to some users, the following stack should have you covered 24/7. Add in 20mg of Cardarine once a day and then include 5–20mg of SR9009 before you exercise.

For recomping, you should try a stack consisting of Stenabolic, Ostarine Ostabolic (MK2866) 25mg a day + Testolone (RAD140) 10mg a day.

During the post cycle, you can use Stenabolic freely at 5–20mg a day. This will keep your endurance levels high and your fat levels low. The same dosage goes for using it solo.

Side Effects

Despite it not being FDA approved just yet, SR9009 is pretty safe to use. SR9009 is non-hormonal, non-estrogenic, and non-androgenic. Just follow the recommended dosage and you will experience no side effects.

You will be happy to know that Stenabolic also does no damage to your liver. However, some users recommend using liver supplements while you are on it.

Finally, if you notice anything unusual while using Stenabolic, do stop using it immediately. It would also be advisable to consult your healthcare specialist.

With it having few to no proven side effects, it is also deemed safe to use, if used correctly.

However, be aware that it is still a drug, so you should never abuse SR9009.

Given that Stenabolic is still not studied enough, we would advise you not to get into using it without thorough prior research.

We hope that what we found will help you decide if you are in two minds about using SR9009.
