OSTARINE Overview Information
Ostarine is an investigational drug that has not yet been approved by the US Food and Drug Administration (FDA). It is part of a class of drugs called selective androgen receptor modulators (SARMs). Some supplement companies have included ostarine in products for bodybuilding. The FDA considers supplements containing ostarine to be illegal.
Ostarine is used by mouth to improve athletic performance and for involuntary weight loss in people who are very ill, also known as cachexia or wasting syndrome. But there is very little good scientific research to support these uses.
How does it work?
Ostarine attaches to proteins in the body known as androgen receptors. When ostarine binds to these receptors, it tells the muscles in the body to grow. Unlike some other chemicals that bind to androgen receptors, such as steroids, ostarine doesn't seem to cause as many side effects in other parts of the body.
OSTARINE Uses & Effectiveness 
Insufficient Evidence for:
- Involuntary weight loss in people who are very ill (cachexia or wasting syndrome). Early research shows that taking ostarine can increase lean body mass by a small amount in cancer patients who seem to be losing weight.
- Age-related muscle loss (sarcopenia). Early research shows that taking ostarine can increase lean body mass by a small amount in elderly adults.
- A group of inherited disorders that cause muscle weakness and muscle loss (muscular dystrophy).
- Breast cancer.
- Loss of bladder control (urinary incontinence).
- Other conditions.
OSTARINE Side Effects & Safety
When taken by mouth: Ostarine is POSSIBLY UNSAFE when taken by mouth. Liver damage has been reported in some people taking ostarine. Other common side effects of ostarine include stomach pain, constipation, diarrhea, headache, nausea, fever, heart attack, and stroke.
Special Precautions & Warnings:
Pregnancy and breast-feeding: There isn't enough reliable information to know if ostarine is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.Liver problems: Ostarine might cause liver problems in some people. People with a history of liver problems should avoid ostarine.
OSTARINE Dosing
The appropriate dose of ostarine depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for ostarine. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
