MYO SR (Brand name), manufactured by Savage Line Lab in Canada, has garnered attention for its unique properties. It boosts the power of Rev-ErbA proteins, the key players in governing your body’s internal stamina, metabolism, and energy use.

This intriguing mechanism has captivated the fitness world, promising to boost endurance, accelerate fat loss, and elevate overall performance. Bodybuilders have found this SARMs to be particularly beneficial during cutting phases. Its ability to boost fat oxidation helps individuals shed stubborn body fat while preserving lean muscle mass.

In this blog post, we’ll look into the uses, dosage, benefits, and potential side effects of SR-9009.

What is Stenabolic SR-9009?

What is Stenabolic SR-9009?

Stenabolic SR-9009, known for its influence on metabolism by activating the protein Rev-erb-alpha, is revolutionary for athletes and bodybuilders. Crafted by Professor Thomas Burris, this research drug amps energy production and endurance, all essential for pushing physical limits. 

Upping mitochondria count in skeletal muscle through Rev-ErbA-α activation notably boosts exercise capacity. Its formal name is 3-[[[(4-Chlorophenyl)methyl][(5-nitro-2-thienyl)methyl]amino]methyl]-1-pyrrolidine-carboxylic acid ethyl ester with a molecular formula of C20H24ClN3O4S. 

It enhances energy levels and endurance. MYO SR from Savage Line Labs also tackles inflammation, improves lipid metabolism, aids in fat burning, promotes muscle strength, and speeds up recovery. According to “Drug Candidate Leads to Improved Endurance By Eric Sauter” One of the severe side effects is liver harm with elevated enzyme levels.

How Does Stenabolic Work?

Stenabolic works by activating a protein called Rev-ErbA, which regulates the body’s circadian rhythm and metabolism. It ignites your energy levels and stamina through a multi-faceted approach. Enhancing circulation ensures oxygen and nutrients reach your cells more efficiently, turbocharging energy production.

Despite reducing your heart rate, MYO SR keeps your metabolism firing, striking a perfect balance. This compound also enhances glucose uptake and fortifies your cellular powerhouses, the mitochondria.

Stenabolic Use Cases

Stenabolic Use Cases

MYO SR is used during the cutting phase. This compound has gained popularity for its ability to assist bodybuilders in shedding excess body fat while preserving hard-earned lean muscle mass. Beyond the fat-loss benefits, SR9009 is renowned for enhancing stamina and endurance, making it a top choice for athletes striving to elevate their performance.

In animal studies, Stenabolic SR-9009 has been shown to increase endurance, reduce body fat, and improve muscle growth.

A study in rats found that Stenabolic SR-9009 improved insulin sensitivity and reduced blood sugar levels. However, it is not approved for human consumption and its long-term safety and efficacy are unknown.

MYO SR Cycle & Dosage

For beginners, a MYO SR cycle involves a daily dosage of 10mg, divided into 2-3 doses. Cycle duration is 10-12 weeks. For advanced users, a MYO SR cycle length is 12 weeks. Start with 20 mg daily, split into 2-3 doses.

Stenabolic Stacks

For an impressive fat loss and endurance stack in bodybuilding, consider combining Cardarine and MYO SR. A daily dose of 20mg of Cardarine and 30mg SR9009 is ideal. Remember, SR9009 should be taken more frequently due to its short half-life.

Try 10mg each with breakfast and your last meal, then an extra 10mg of SR9009 30 minutes before your workout. Both compounds are non-hormonal and stimulant-free, ensuring a good night’s sleep. Boost the anabolic effects by stacking with LGD-4033 or YK11.

Are SARMs Better than Anabolic Steroids?

In the comparison between SARMs and anabolic steroids, the choice hinges on individual priorities and risk tolerance. Unlike anabolic steroids, SARMs, less studied and less effective, offer potential benefits of fewer side effects but lack approval for human use. Anabolic steroids, well-researched and potent, yield significant muscle gains but come with more pronounced side effects and legal restrictions. The decision resembles choosing between a rocky, adventurous route (SARMs) and a smoother, regulated path (anabolic steroids) to fitness goals.
