What is Stenabolic (SR9009)?

Stenabolic, also known as SR9009, is a research compound known for its potential to enhance endurance and metabolic function. Originally developed for its medical applications in treating metabolic and cardiovascular conditions, Stenabolic has garnered interest in the fitness and performance enhancement communities. It functions as a Rev-Erb agonist, activating specific receptors that play a role in regulating circadian rhythms, energy metabolism, and mitochondrial function. This activation is believed to lead to improved endurance, increased fat metabolism, and potentially other benefits related to overall fitness.

How Stenabolic (SR9009) Works

Stenabolic is a synthetic compound categorized as a Rev-Erb agonist. Unlike traditional performance-enhancing drugs, Stenabolic does not directly affect androgen receptors or hormone levels. Instead, it works by targeting the body’s circadian rhythm and metabolism through its interaction with the Rev-Erb receptors.

When ingested, Stenabolic binds to the Rev-Erb receptors, which play a crucial role in regulating the body’s internal clock, metabolism, and energy expenditure. By activating these receptors, it helps regulate the expression of genes involved in various metabolic processes, including glucose and lipid metabolism, mitochondrial biogenesis, and inflammation.

One of the primary mechanisms through which Stenabolic works is by increasing the activity of mitochondria, the powerhouse of the cell responsible for producing energy. By enhancing mitochondrial function, it increases the body’s overall energy expenditure, leading to improved endurance, stamina, and fat oxidation. This can result in increased energy levels and enhanced athletic performance during physical activity.

Moreover, Stenabolic has been shown to have potential benefits for individuals looking to improve their body composition. By increasing energy expenditure and fat oxidation, it may help reduce body fat levels and promote a leaner, more muscular physique. Additionally, it may have a positive impact on cholesterol levels and insulin sensitivity, further contributing to improved metabolic health.

Overall, Stenabolic works by targeting the body’s circadian rhythm and metabolism through its interaction with the Rev-Erb receptors. By activating these receptors, it enhances mitochondrial function, increases energy expenditure, and promotes fat oxidation, leading to improvements in endurance, stamina, and body composition. While it shows promise as a potential performance-enhancing compound, it’s important to note that the long-term safety and efficacy in humans are still being researched, and its use may come with potential risks and side effects. Individuals considering using should consult with a healthcare professional before doing so.

Working Out

Stenabolic is believed to offer potential benefits for individuals looking to enhance their workout performance and fitness goals, primarily through its reported effects on endurance and metabolism. Here’s how Stenabolic may help with working out:

  • Enhanced Endurance: It is known for its potential to significantly improve endurance levels. It works by activating the Rev-Erb protein, which plays a role in regulating circadian rhythms and metabolic processes. This activation can lead to increased stamina, allowing individuals to engage in longer and more intense workouts without experiencing fatigue quickly.
  • Fat Metabolism: It is believed to enhance the body’s ability to metabolize fat for energy. It may increase the utilization of stored fat as a primary energy source during exercise. This effect can be particularly beneficial for those looking to shed excess body fat and improve body composition.
  • Improved Cardiovascular Health: Some research suggests that it may have cardiovascular benefits, such as improving lipid profiles and reducing the risk of metabolic disorders. This could indirectly support overall workout performance and health.
  • Better Recovery: Users have reported reduced recovery times between workouts. This can be attributed to its ability to promote efficient energy utilization and reduce muscle soreness. Quicker recovery allows individuals to train more frequently and consistently.
  • Preservation of Muscle Mass: While not primarily known for its muscle-building properties, it may help individuals preserve lean muscle mass, even during calorie deficits or intense training. This can be advantageous for those aiming to maintain muscle definition while reducing body fat.
  • Increased Motivation: Some users have reported improved mood and motivation while using it. This can contribute to a more positive mindset and better adherence to workout routines.

Hair Loss

There is no scientific evidence or information suggesting that Stenabolic has any direct impact on hair growth or hair loss. Stenabolic primarily targets Rev-ErbA proteins to influence metabolic processes and circadian rhythms, and its mechanisms of action are not related to hair-related processes.

Hair growth and hair loss are primarily regulated by genetic factors, hormonal imbalances, and other complex mechanisms within the body. Substances like Stenabolic, which are primarily studied for their potential metabolic effects and performance-enhancing properties, do not typically interfere with these hair-related processes.

User-reported side effects related to hair loss or hair growth specifically attributed to Stenabolic are limited, and the available information is primarily anecdotal. Some users have reported experiencing hair-related issues while using SARMs, but it’s essential to note that these accounts are not supported by comprehensive scientific research and may not be directly linked to Stenabolic itself. Here are some user-reported side effects related to hair:

  • Hair Shedding: Some individuals have reported increased hair shedding while using Stenabolic. Hair shedding can be a common occurrence and may not necessarily indicate permanent hair loss.
  • Thinning Hair: A few users have mentioned experiencing hair thinning or reduced hair volume while using Stenabolic. Again, these reports are anecdotal and not well-documented.
  • Change in Hair Texture: In rare cases, users have noted changes in hair texture, such as coarsening or changes in hair quality.


In conclusion, Stenabolic (SR9009) is primarily studied for its potential effects on metabolic regulation and circadian rhythms, and it is not directly associated with causing hair loss. While some individuals have reported concerns about hair changes while using Stenabolic, these reports are anecdotal and not universally experienced. The mechanisms of action of Stenabolic primarily target metabolic processes and do not specifically interfere with hair-related mechanisms
