A review of Stenabolic: Dosages, results and side effects

SR-9009 Stenabolic benefits, results and side effects

What is Stenabolic?

Stenabolic, also known as SR9009, is a research compound often marketed as a SARM (Selective Androgen Receptor Modulator). In reality, Stenabolic is not a SARM at all, it is actually 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 Stenabolic 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 research with this product. 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.

Stenabolic benefits

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 Stenabolic 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.

Increased endurance

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.

Reduced inflamation

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.

Reduced anxiety

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 dose for Stenabolic 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 half-life

Stenabolic has a half-life of 4-6 hours. This means that in order to keep optimal levels of this compound in our body, to achieve to best results, we should take a dosage 3 times a day.

So 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.

How to take Stenabolic

The bioavailability of Stenabolic is lower than other SARMs. This means the body only absorbs a small amount of the substance when taking orally, which is a real downside.

But there is a solution, and that is sublingual use. This means we should keep the liquid SR9009 under our tongue for about 10 seconds before we swallow. This way, the tissue under our tongue absorbs almost all of the Stenabolic.

This route of administration is far more effective than just using it orally.

Stenabolic FAQ

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 Stenabolic 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 should I take Stenabolic?

SR-9009 has a low bioavailability when taken orally. It is therefore highly recommended to use it sublingually.
