SR9009 (Stenabolic)

I am eager to tell you about one of the most potent weapons that you can use in your fitness arsenal to maximize endurance and fat loss.  This research drug is called Stenabolic (sr9009) and in this article, I will teach you all about it.  Whether you are a seasoned professional athlete or just a normal joe,  you can enjoy the benefits.

Stenabolic (SR9009) Review


Stenabolic (sr9009) was developed at the Scripps research institute by Professor Thomas Burris.  It is NOT a SARM (selective androgen receptor modulator), but it is a Rev-Erba agonist drug.  In 2013, the Journal of Natural Medicine published a study showing that it helped with endurance and obesity in animal models.   Although Stenabolic (sr9009) is not FDA approved, it has since been purchased as a research chemical by athletes of all levels to help them boost endurance and fat loss.

Rev-erb-α is a major physiological regulator of mitochondrial content and oxidative function. Thus, pharmacological activation of Rev-erb-α may be a promising approach for the treatment of skeletal muscle diseases with compromised exercise capacity. – Natural Medicine

How it works

If we take a look at the Natural Medicine study we can figure out how Stenabolic (sr9009) actually works and it is pretty cool.  The glaring thing they found was that it drastically reduced obesity in animals and can be described as ‘exercise in a bottle‘.

The Science

The study shows that Stenabolic (sr9009) actually alters the core biological clock.  That clock is responsible for synchronizing the rhythm of the body’s activity all day and night.  Think of it as the clock on your iPhone, which automatically displays the time and adjusts when needed (like for time zone or daylight savings time).

How it does this is also pretty simple.  Our bodies have a natural molecule structure called Rev-erbA, which is responsible for doing several things, including controlling glucose and lipid metabolism in our liver, storing fat cells, and removing dead or dying cells during inflammation.

The Results

Rodents that lacked Rev-Erba had less skeletal metabolic and muscle activity, while also struggling with cardio capacity.  Once this was corrected with Stenabolic (sr9009), their Rev-Erba was now activated and their metabolic activity and cardio skyrocketed.  In fact, their running distance and running times improved by over 40%!

Another crazy thing happened as well.  Those rodents developed muscles like a seasoned athlete who had been training years in a very short time.  The theory as to why is their gene expression had been altered, and the reason for all this was that the Rev-erbA activation caused new mitochondria, while ridding the body of the ineffective ones.  Studies in France and the Netherlands also showed similar results.

Athletic uses

Okay so let’s translate all this scientific jargon into a real-world language to figure out how using Stenabolic (sr9009) can help you.


It doesn’t take a genius to realize how awesome it could be to actually improve your gene expression. AND turn you into an experienced athlete in a short time.

Just imagine if you were already in great shape what this stuff could do.  Let me explain why you should use Stenabolic (sr9009) if you want to boost your endurance.

Many of us use stimulants before a workout, but did you know that using them actually HURTS our workouts instead of helping?  Yes, it is true.

The Problem With Cardio…

When you do cardio, the idea is to rev up your heart rate where your capacity is maximized.  This is why people new to running get winded so easy. But someone who has been running years can go many miles with no problem.

Someone who is struggling with cardio will have their heart rate shoot up if they were to sprint. Up to 90% of their maximum heart rate.

Well when you use stimulants you hit that 90% much faster during your workout, so it actually is slowing you down.

How Stenabolic Fixes That:

Stenabolic (sr9009) will actually do the complete opposite.  So if you were to sprint at the same speed as before, you might only go up to 75% of your maximum heart rate.  Now you have more room to push harder, WITHOUT being winded so fast.  This is how it works at improving cardio and your weight training in the gym.

Fat loss:

stenabolic sr9009 benefitsWhether you are obese or already lean, you can still safely use Stenabolic (sr9009) to cut down on body fat because it isn’t a stimulant or harsh drug.  Studies showed subjects burned fat using it even while resting.  When they did exercise the fat loss accelerated quite drastically and this is due to two main reasons.  The first is the rise in metabolic rate which was discussed earlier in the article.  The second is that it will force the body to burn away stored fat because of the increase in mitochondria strength and glucose uptake.  Pretty cool stuff!

Improved Cholesterol Levels

That isn’t all! For our obese friends reading this, Stenabolic (sr9009) also will help improve your cholesterol levels. And rid the body of excess glucose in your muscles.  This will put you into fat burning mode much quicker during and post exercise.  You will be able to get much quicker results out of your workouts.  Your friends will be wondering how you lost so much weight so fast!

Treatment of diet-induced obese mice with a REV-ERB agonist decreased obesity by reducing fat mass and markedly improving dyslipidaemia and hyperglycaemia. These results indicate that synthetic REV-ERB ligands that pharmacologically target the circadian rhythm may be beneficial in the treatment of sleep disorders as well as metabolic diseases. – PubMed

How to use Stenabolic Properly

Stacking ideas

Stenabolic (sr9009) can be used in a stack, during post cycle, and of course used on its own.

Those who want to use a cutting steroid stack, a good suggestion is Stenabolic (sr9009) at 5-20mgs per day. Stacking with Primobolan at 400mgs a week and a light Testosterone dose.

A good SARMs (selective androgen receptor modulator) stack is Stenabolic (sr9009) at 5-20mgs per day with 10mgs a day Ligandrol LGD (Anabolicum) + 20mgs a day Cardarine (GW501516).

During post cycle feel free to use it at 5-20mgs per day to help keep your endurance strong and fat off.  The same dosage applies to solo use.

How to dose

There is A LOT of confusion out there on how to dose Stenabolic (sr9009) and the blame is solely on cookie cutter parroted information.  If you do not use this drug correctly, you will woefully undercut your results.  The correct way to use it is dosing it at 5-20mgs 1-2 hours pre-exercise.  Example:  If you do cardio at 9 am in the morning, take a dose 1-2 hours prior.  Then if you have sex at 1 pm, dose it the same prior.  Then if you weight train at 5 pm, dose it prior.

If you don’t do any sort of physical activity all day, you can use it once or twice that day splitting the dose between AM/PM.  However, you need to exercise to get the most out of this drug.

Side effects of SR9009

Stenabolic (sr9009) is nonhormonal, nonestrogenic, non-androgenic, and users have reported no side effects when it is used correctly.

Where to buy

Stenabolic (sr9009) is not yet approved. Therefore, to purchase it you need to find a good source which sells research chemicals.  Many companies are putting out bunk products or mixing in things like clenbuterol to trick consumers.  If you check out our websites at and you can find approved sourcesbuy stenabolic sr9009
