Stenabolic – SR9009

Stenabolic, or SR9009, is a compound that will appeal to athletes who are particularly focused on wanting to improve endurance and recovery. It can also have some benefits for fat loss.

While not one of the most powerful substances an athlete can use, SR9009 still has its uses and works particularly well when combined with more potent compounds.

The lack of human based research on Stenabolic means there is not a lot of data about exactly what it can do, although research on lab mice showed certain improvements in important areas like exercise capacity and making better use of stored fat as energy. Stenabolic may also provide some important benefits for recovery centered around sleep.

Stenabolic is another compound which is often referred to as a SARM but is technically not a SARM at all. In scientific speak it is known as an agonist of Rev-ErbA, but for those of you without a chemistry degree the main interest is in what SR9009 can do for your performance and results.

Initial lab studies showed that SR9009 was effective at increasing exercise capacity. It was also found that Stenabolic alters the circadian rhythm in mice but as this was an experimental research with unknown effects in humans, it’s still not fully understood how Stenabolic would impact on the human circadian rhythm, either positively or negatively.

Bodybuilders and other athletes who have used Stenabolic have determined that it is very beneficial in some specific areas of interest: mainly in increasing endurance and stamina, as well as for fat loss.

As this is a research drug only and is not approved for use in humans, no official manufacturer of Stenabolic takes place and the only way to purchase it is through companies who sell it as a research chemical.

The scientist who created Stenabolic has stated that this compound may have little to no bioavailability in humans when taken orally as it does not make its way into the bloodstream.

However, those that use the drug for performance enhancing purposes often report a high rate of bioavailability, potentially indicating the possible downplaying by official sources of the true effectiveness and beneficial effects of Stenabolic to discourage use. Many people are using this compound with exceptional results despite the lack of official scientific research of its effects on humans.

Despite this, and the range of unknowns that surround the overall effects of Stenabolic, it is still listed as a prohibited drug by WADA because of its performance enhancing abilities.

Dosage Instructions

Like most things about this compound, there is no consensus on dosage for performance enhancement either and most users will experiment with their own dosages and cycles.

We know that Stenabolic has a very short half-life of about 4 hours only so you will want to be timing your intake so it matches up to when you need the effects to kick in and this will usually be about 2 hours before you start a workout at which point its activity in the body will be at the optimal level.

A dosage of under 20mg is suitable for just about anyone, and good effects can even be seen at just 5mg, but most people will want to multiply that dosage. This is a compound that’s suitable for using with steroids or other SARMs in a stack.

When considering your dosage, you need to be aware that Stenabolic has a very short half-life: just four hours approximately. So, it not only starts working quickly but also leaves the system quickly, meaning to maintain the optimal level of this compound you’ll need to split the dosage into two or more daily.

For some people though, a single daily dose might fit with your goals such as powering an upcoming workout and keeping you focused throughout it. In this case it’s best to take your once daily dose about an hour before working out.

Those who want the effects of Stenabolic to last for longer than a single workout are likely to follow the option of splitting the dose into two or three times a day. This can provide greater benefits for sleep quality and maintaining mental focus for longer periods.

When making this decision you should be considering not only the physical effects of SR9009 but the mental benefits as well; and for that reason, most people will benefit from splitting the dose to keep the effects at their peak.

The absolute maximum dose of Stenabolic that is considered safe is 50mg per day. For most users, that level of dosage will be beyond what is required, and many users see good results with as little as 5mg daily which is a good place for new users to start where you can then evaluate the effects of SR 9009 and adjust the dosage as needed.

Most users find a balance at around 30mg daily, and by splitting this into three doses of 10mg three times per day you maintain optimal levels of Stenabolic and reduce the risk of sleeping issues occurring. Higher doses of Stenabolic may run the risk of inducing insomnia which is the opposite effect of what you want to achieve when it comes to improving your quality of rest, recovery and sleep.

Effect on Cycle

Lab studies have shown that SR-9009 improved oxygen consumption, muscle mitochondria and muscular use of glucose while decrease liver fat cell formation and body fat storage. Studies on mice showed fat loss over a 7-day period indicating this compound works quickly.

Stenabolic makes the body more efficient use of energy sources, so your athletic performance hits a much higher level than normal. Studies have also shown that the metabolic rate at rest can be raised with Stenabolic so you store less fat and burn up more fat when at rest.

  • Endurance and stamina – This are the main effect that brought attention to Stenabolic, with lab results on mice showing a significant increase in endurance capacity. This makes it useful for endurance athletes like runners, swimmers and cyclists and anyone doing cardio work. But bodybuilders wanting to increase capacity for lifting weights can also benefit.
  • Fat Loss – With its ability to improve metabolism and make more efficient use of stored fat, SR9009 can contribute to weight loss, and this was also shown in studies on mice. Through a complex set of processes in the body, mitochondrial cells may be enhanced by Stenabolic particularly in fat cells, the liver and skeletal muscle. This action can help with the process of fat being used for an energy source, which can only result in you burning up more fat faster, without losing muscle tissue.
  • Increase Lean Muscle Mass – SR9009 might be able to speed up the gaining of lean muscle. This can make it useful to stack with powerful muscle gaining compounds where it can act as a supportive compound. When combined with a compound like Cardarine, Stenabolic can work to maintain your existing muscle especially when your diet is calorie deficit for fat loss.
  • Recovery – Stenabolic can help reduce inflammation and damage to tissues, which helps you recover after intensive exercise. Just as importantly is SR-9009’s effects on sleep because the better sleep we get, the faster and more efficiently the body will recover from a workout and have you ready for your next workout.
  • Inflammation – Stenabolic can potentially reduce the body’s inflammation response which enhances recovery and reduces the risk of injury.
  • Cholesterol – Stenabolic may lower cholesterol if these effects in mice can translate to humans. It has been touted as being particularly beneficial for people with existing high cholesterol, which is the opposite effect of most anabolic steroids which will have a serious negative impact on cholesterol levels.
  • Mental – Through optimizing the circadian rhythm, Stenabolic may improve sleep quality, and help you remain more focused and alert during the day. This boosts all over mental wellbeing and mental energy, putting you in the right frame of mind for your workouts and potentially reducing the mental fatigue that can drag down the intensity of your workouts and hamper your results.

Stenabolic is as useful for its physical benefits as for its positive effects on the mind which will ultimately help to improve your workout capacity and keep you focused. Sleep quality, fat loss and increased endurance are where the main benefits of SR-9009 are focused. Fat loss and retaining muscle while cutting are other additional benefits of this compound.

Additional Information

  • Insomnia
  • Testosterone suppression
  • Possible blading
  • Acne
  • Water retention6

When you are using this compound at moderate doses for restricted periods of time, the risk of side effects is minimal based on personal experience.

That doesn’t mean that Stenabolic will not cause side effects for you as an individual, but it certainly won’t be causing the same adverse effects that we see with anabolic steroids.

What is known so far about people using Stenabolic is that there are no reports of liver toxicity. As with any substance, avoiding high doses is the key to protecting the liver, as is limiting your usage time to a sensible cycle length and taking breaks between cycles to allow the body to recover.

An unusual side effect that has been noted by some users is that of insomnia. Considering Stenabolic’s activity on the body’s circadian rhythm which dictates sleep, it might come as some surprise that this effect can take the opposite direction to what is intended.

But if a person is taking too much Stenabolic, it’s possible for the body to become over reactive and this can negatively impact sleep quality – starting a cascade effect on your results and recovery. Reducing your dosage is the ideal way to prevent this side effect, while keeping in mind it has only been reported by a small minority of SR-9009 users.

When it comes to the issues that any steroid user would be familiar with testosterone suppression, androgenic effects like balding or acne, or estrogenic effects like water retention – these are not a concern with Stenabolic. The compound has no hormonal activity, so it doesn’t have any impact on either testosterone or estrogen. This means you won’t need to take any estrogen blocking drugs or any PCT drugs afterwards; unless you are stacking Stenabolic with a steroid or other compound that does affect these hormones.
