Ostarine – Uses, Side Effects, and More

What is Ostarine?

SARM Ostarine, also known as MK-2866, is a SARM (Selective Androgenic Receptor Module) developed by GTx. It is designed to prevent and correct muscle atrophy and amyotrophy from reduced stress. It can also be used as a means of preventing cachexia, sarcopenia, and as hormone or testosterone replacement therapy.

This type of SARM not only maintains existing muscle mass but also builds it. Ostarine is often confused with S1, but S1 was created earlier in development and is not nearly as effective.

Benefits of Ostarine

SARM MK-2866 gives you the following benefits:

  • Increased lean muscle mass
  • More power
  • More stamina
  • Better healing abilities after injuries
  • Anabolic effect (even at low doses of just 3mg)


Are there any side effects with Ostarine?

Ostarine is currently in a legal gray area as authorities have yet to agree on whether the substance should be classified as legal or illegal.

Because there are some side effects that should not be ignored. Here is a list of the most common ones:

  • Severe and persistent headache
  • Hormonal imbalances can occur due to increased estradiol levels.
  • Severe back pain
  • Women can potentially experience problems with their menstrual cycle.

In addition, there are some effects that may occur after the cycle:

  • Aching muscles
  • Aching joints
  • Nightmares and generally poor sleep quality

This information indicates that the side effects of SARM can be serious. Because research is busy taking more of Ostarine.

Therefore, if you are already a user of this anabolic SARM, you should always keep an eye on the available research. However, if you have not yet resorted to this product to improve your strength and muscle structure, it is important to carefully assess your health in advance.

Because the side effects of Ostarine are more common in people with pre-existing health problems.


Usage and Results

If you use Ostarine at a dose of 30mg per day, you can expect to gain 2-3 kg (5-7 lb) in 10 weeks. Ostarine is not as highly anabolic as other SARMs and as such it is mainly used for reduction in order to maintain as much muscle mass as possible.


Advantages – Increase in Muscle Mass and Strength

Ostarine has excellent anabolic properties, as the main purpose of MK-2866 synthesis is to stop diseases that cause muscle wasting. Most people seem to think that the ostealis is for reduction only, but that’s not true. There are dozens of reviews on the Internet from people who have used Ostarine and gained significant muscle mass.

MK-2866’s ability to build muscle has also been confirmed by numerous clinical studies.

In one study, a group of elderly people took 3 mg of Ostarine for 12 weeks. As a result, all participants saw an improvement in their physical condition, accompanied by an increase in muscle mass and body fat loss. Those in the group taking 3mg per day gained an average of 1.3kg of lean muscle mass and lost 0.6kg of fat.

In another study, 159 cancer patients were divided into two groups receiving 1 mg and 3 mg of MYO-STA MK-2866, respectively, for 4 months. Both groups saw results similar to the first study, without any side effects.

  • Fat Tissue Loss

The most popular use for athletes is to use Ostarine. Normally, when we are in a chronic calorie deficit, we lose not only fat but also muscle tissue. Thanks to its unique properties, Ostarine protects the muscles in adverse conditions, so we lose almost exclusively fat when cutting. In addition, as we have seen in the studies mentioned above, Ostarine itself accelerates body fat loss.

  • Improving the Condition of Bone Tissue

With increasing age, the density of our bone tissue decreases as a result of lower levels of sex hormones. This often leads to bone diseases such as osteoporosis. Since androgen receptors are also found in the bones, Ostarine reverses this process and speeds up the healing rate after broken bones.

  • Protects The Heart

A clinical study conducted on 120 patients taking 1 mg or 3 mg Ostarine per day showed that Ostarine has a positive effect on the cardiovascular system. All participants noticed a reduction in bad HDL cholesterol and triglyceride levels.

  • Increases İnsulin Sensitivity

In the aforementioned study, Ostarine also lowered the subjects’ mean blood sugar levels, improving insulin sensitivity.
