- Skin changes: This includes acne or other skin-related side effects.
- Sleep Disturbances and Fatigue: Impact on sleep patterns and general tiredness.
- Muscle and Joint Pain: Especially following the onset of use.
Blood Pressure and Cholesterol: Ostarine has been linked to changes in blood pressure and lipid profile, particularly a decrease in HDL cholesterol levels.
Long-Term Health Concerns
The long-term use of Ostarine raises concerns about more serious health risks:
- Hormonal Imbalance: Long-term use may lead to testosterone suppression, potentially requiring post-cycle therapy.
- Liver Damage: Although considered less hepatotoxic compared to traditional steroids, Ostarine use might lead to elevated liver enzymes indicating stress on the liver.
- Heart Risks: There is potential for a heightened risk of heart attack or other cardiovascular issues.
- Vision Alterations: Some users report changes in their vision, a side effect that is not entirely understood.
Comparative Risks with Steroids and SARMs
When comparing Ostarine to traditional anabolic steroids, it’s essential to understand their relative risks:
Gynecomastia and Water Retention: Ostarine typically leads to fewer estrogen-related side effects like gynecomastia and water retention compared to anabolic steroids.
Reduced Liver Toxicity: SARMs like Ostarine are generally believed to pose a lower risk of liver toxicity than anabolic steroids.
However, the lack of long-term studies on SARMs means that the long-term risks and the potential for cancer development are not as well-established as they are for anabolic steroids.

Impact on Specific Population Groups
The side effects of Ostarine affect different population groups in varying ways, particularly in the context of their specific health conditions and body composition goals.
Elderly Individuals
Elderly individuals, especially men, may use Ostarine in an effort to increase lean body mass and improve strength. Ostarine has been researched for its potential to counteract sarcopenia, the age-related loss of muscle mass and strength. However, the use of Ostarine can also lead to side effects such as hormonal imbalance and the potential exacerbation of pre-existing conditions.
Athletes and Bodybuilders
Athletes and bodybuilders often seek the muscle growth and strength enhancement benefits of Ostarine. While it can assist in creating a more favorable body composition by increasing lean body mass, the risk of adverse effects such as liver toxicity and cardiovascular issues is present. Additionally, athletes using Ostarine may face sanctions from sports federations due to its classification as a banned substance in most competitive sports.
Cancer Patients
For cancer patients experiencing cachexia, Ostarine has been studied in clinical trials for its muscle-wasting properties. It may aid in muscle growth and improve physical function. Nonetheless, in such a vulnerable group, side effects such as nausea, fatigue, or hormonal disturbances warrant careful consideration when evaluating the risk-benefit ratio for its use.
