What is Stenabolic?
Stenabolic, also known as SR9009, is a research compound often marketed as a SARM (Selective Androgen Receptor Modulator). In reality, it is not a SARM at all but a Rev-ErbA ligand. This means that it’s a molecule that binds itself to the Rev-Erb protein and enhances its activity in our body. Rev-ErbA is a protein that is highly present in our liver, fat, muscles and skeletal muscles.
An important aspect of this compound is that it is non-hormonal. As such, it does not suppress the natural production of testosterone, which means that there is no need for any kind of PCT.
How does Stenabolic work?
What this compound does is it stimulates and activates the Rev-ErbA, which increases mitochondria. This then leads to increased stamina, endurance, and exercise capacity.
It’s the main reason why bodybuilders and athletes use this compound. It could significantly enhance endurance and fat loss.
The study showed that mice lacking Rev-Erbα had decreased muscle metabolic activity and running capacity. However, Burris’ group demonstrated that activation of Rev-Erbα using Stenabolic led to increased metabolic activity in skeletal muscle in both culture and mice. The difference was a 50% increase in running capacity for mice treated with SR9009 – even when exercise was restricted.
Basically, SR-9009 is one of the strongest endurance boosters out there. It has many similarities with Cardarine.
Benefits of SR9009 are:
- Fat loss
- Improved cholesterol and cardiovascular health
- Increased endurance
- Reduced inflammation
- Reduced anxiety
The main benefit of Stenabolic is that it promotes fat loss, even without exercise. Therefore, it has the nickname “exercise in a bottle”.
The fat burning effect of this compound was first discovered in animal studies. Rats that received this compound lost fat 60% faster than the other rats.
Anecdotal evidence and user reports show that an increase in fat loss also applies to humans.
Improved cholesterol and cardiovascular health
This is one of the main reasons why SR9009 is currently in extensive research to one day treat cardiovascular diseases. It is a great benefit that I would definitely take advantage of if I had any cholesterol or heart problems.
In animal studies, Stenabolic was given to rats with high cholesterol diet and in 7 days, their blood cholesterol was reduced. This is an incredible health benefit.
An increase in endurance is also one of the main reasons that so many athletes take this compound. In fact, this is the reason that most sports bodies, including the Olympics, listed SR9009 as a banned substance. It gives such an unfair advantage in endurance.
Studies have shown that Stenabolic successfully and effectively reduces inflammation. This isn’t really a benefit that we are that interested in but it’s a nice thing nevertheless.
Another, somewhat surprising, benefit of Stenabolic is that it reduces anxiety. Users commonly report an increased mood while using this compound.
SR9009 side effects
Stenabolic does not work as a fat burner, thyroid accelerator or appetite suppressant – yet still allows an increase in weight and fat loss.
It also doesn’t cause suppression of natural testosterone, nor is it liver toxic.
At this moment, there are actually no known side effects of Stenabolic. However, the lack of clinical trials on this compound means that we don’t know if long-term use will cause side effects.
SR9009 dosage and cycle length
The most common dosage for SR-9009 is 20 to 30 mg per day. This dosage seems to provide the best results, without causing side effects.
The average cycle length for this compound is 8 weeks.
Stenabolic has a short half-life of only 4-6 hours. This means that in order to keep optimal levels of this compound in our body, it is necessary to split the dosage
For example, if you are doing an 8-week cycle of 30mg a day. Take the first dosage of 10mg in the morning, the second dosage of 10mg at lunch and the last dosage in the evening. This way, you will be able to get the best possible results because the compound will be at optimal levels throughout the day.
One of the major disadvantages of SR9009 is its limited bioavailability when taken orally. Research has shown that only 2.2% of Stenabolic taken orally actually reaches the bloodstream. This is considerably lower than Cardarine (GW-501516) or any of the SARMs.
Luckily, there is an easy solution: Taking it sublingually.
Instead of simply swallowing the liquid, you keep it under your tongue for 20 to 30 seconds. It is then absorbed by the mucous membrane leading to faster and more efficient diffusion into the blood.
Stacking SR9009 with SARMs
Because SR9009 is non-hormonal, it’s great for stacking with SARMs (Selective Androgen Receptor Modulators). In fact, most people stack it with SARMs because this will allow us to keep our muscle mass when cutting.
But of course, you can also do an SR9009-only cycle and get great results. You can also keep all your muscle when cutting with Stenabolic, just eat at maintenance calories, this will allow you to keep all your muscle mass and lose fat because of the compound.
The best SARMs to stack with Stenabolic are Ostarine and LGD-4033. They are very well researched and will make you keep all your muscles and even make you put on a few kgs of muscle if you train. Another reason why you should choose these SARMs is that they don’t require a PCT if you use them at normal dosages.

How does SR-9009 work?
Stenabolic is a Rev-Erb ligand. This means that it’s a molecule that binds itself to the Rev-Erb protein and enhances its activity in our body. This has incredible fat loss and endurance increase effects.
Does Stenabolic build muscle?
While SR9009 does not have anabolic effects, it can help build muscle by enhancing endurance. By enabling you to work out longer, it can indirectly improve muscle growth.
When to take Stenabolic?
Because SR-9009 has a short half-life of only 4 to 5 hours, it is recommended to split the dosage in three parts and take it in the morning, afternoon and evening.
How to take Stenabolic?
You should take Stenabolic sublingually. This basically means that you should keep the liquid compound under your tongue for a few seconds before swallowing it.
This is the most optimal way to take SR9009 because it has low bioavailability but this way it gets effectively absorbed into the bloodstream with the help of the tissue under the tongue.
