Are SARMs Steroids? What’s the Difference?

If you are an experienced athlete and at some point noticed that the results do not change from month to month – one of the best options is to try SARMS.

Are SARMs Steroids?

SARMs vs Steroids

Sarms improve strength, increase lean muscle mass, and has a mechanism of action similar to steroids, but are not steroids at the same time. It is because Sarms are not steroids, that’s why they have found great popularity.

Unfortunately, some SARMs such as Ostarine and Cardarine are already on the lists of banned drugs in some countries,1  because they have a strong anabolic effect, but many are still available for purchase: Ligandrol, Ibutamoren (MK 677), RAD-140, Andarine S4

SARMs are famous for their strong anabolic effect, similar to steroids, and at the same time for the absence of side effects inherent to steroid intake. Steroids can be converted to estrogens and cause unpleasant side effects, such as gynecomastia, high blood pressure, etc.

Steroids can also be converted to estrogens. Sarms are not converted to estrogens and therefore does not cause such side effects. It should be understood that the effect of SARMs will be lower than that of taking strong steroids, but it will be much safer. SARMs are also excellent for women athletes because of their weak impact on the hormonal system.

  • Increase strength
