Stenabolic (SR9009) is SARM and research chemical, and it can be compared to Cardarine (GW-501516), as it is also an agonist of Rev-ErbA.
SR9009 enhances exercise capacity in mice by increasing mitochondria in skeletal muscle. This is why it has been marketed and hyped around the internet as exercise in a bottle.
Stenabolic has the ability to alter the activity of the skeletal muscle mitochondria, or in simple terms - it boosts your metabolic activity. This makes it similar to what DNP does, being SR9009 much safer and not counter productive to your endurance goals. SR9009 has the ability to mimic actual aerobic exercise without actually putting in the conditioning. Therefore, it will boost your endurance instead of hurting it.
Stenabolic (SR9009) will help a person become leaner, and it will help them do more distance with cardio without getting winded as fast. Overall, it will increase your VO2 max, allowing you to improve your endurance.
SR9009 can also benefit non athletes as well, since it can reverse obesity, metabolic syndrome, and type 2 diabetes.
Stenabolic should be dosed at 20-30 milligrams (mg) per day and adjusted up or down by 10mg depending on user preference. Regarding the cycle duration, the typical cycle length is 6-8 weeks, and it would be wise to stack SR9009 with Cardarine (GW-501516) for a double dose of endurance power.
