Guide to Ostarine: Uses, Benefits, Side Effects, and Dosage


Over the last few years, Ostarine has become increasingly popular. Ostarine, also known as MK 2866, is one of the most popular SARMs on the market. This substance allows users to gain muscle mass and lose fat quickly. 


Researchers found out that it could help as treatment for muscle wasting illnesses and osteoporosis. They discovered that it might significantly increase lean muscle mass. Additionally, this drug produces less negative side effects than the traditional anabolics. As a result, bodybuilders are now using it to develop muscle bulk. In addition this  improve their performance.

MK-2866 is still in phase 2 trials and is currently studied for a variety of applications. It is not available to the general public because it is still under investigation. However, it is still easily available on the internet as a research chemical that is not intended for human use.

We’ll go over the benefits of Ostarine, uses, dosages, side effects, and much more in this article.


Uses and Benefits of Ostarine

Rapid Muscle Growth

Ostarine produces rapid muscle growth. It is perhaps its most well-known benefit. Bodybuilders and athletes use Ostarine for a variety of reasons, including this.

A study found that after 16 weeks of use at 1mg and 3mg, lean muscle mass increased by 2-3 pounds. In the past, researchers created MK-2866 to replicate the benefits of actual steroids. The purpose was to avoid the negative side effects such as gynecomastia and acne.

This SARM is notable for having a significant androgen receptor action. It is comparable to a low-dose steroid cycle. 

Accelerated Fat Loss

Because of the anabolic nature of Ostarine, taking MK-2866 increases your metabolic rate. Thus, this makes it much easier to shed weight. MK2866 is currently one of the most effective SARMs for fat loss. This also maintains leanness during a bulking cycle.

To put it another way, when the Ostarine is working to create muscle in your body. It burns calories at a much higher pace, helping you to burn fat while gaining muscle with relative ease.

Increased Bone Density

Ostarine does not only increases lean muscle mass in users. It also enhances bone density, which is very important in the aged.

Ostarine is currently being studied in clinical trials. This drug is a possible treatment to reduce bone fractures in patients with bone wasting illnesses.

Improved Insulin Resistance

Ostarine may aid in the reduction of insulin resistance and blood glucose levels. This could lead to improved nutrient absorption and faster muscle recovery.


Side Effects of Ostarine

The majority of persons who use MK-2866 do not have any negative health effects. However, researchers discovered that it may have some negative effects.


The following are some of the possible adverse outcomes:

  • Decreased HDL Levels
  • Headache
  • Back Acne
  • High Blood Pressure
  • Joint Pain
  • Increased Hunger


Long-term side effects are still being researched. The suppression of natural testosterone is the most well-known side effect. Again, most people who take MK-2866 for bodybuilding don’t have many adverse effects. In addition, more long-term research is needed.

Taking a post-cycle therapy, like with other SARMs, is highly suggested. The goal of post-cycle therapy (PCT) is to get your testosterone levels back to normal. As a post-cycle therapy, the first option is to use a natural, over-the-counter testosterone booster.

Dosage of Ostarine

Ostarine has been demonstrated to work at very low doses, as little as 1 to 3 mg. The normal daily dosage would be between 10 and 30 milligrams. There is no scientific evidence that these dosages are better. Yet, anecdotally, these dosages can result in greater muscular gains.


Ostarine has a half-life of roughly 24 hours. That means that if you’re going to run a cycle, taking it once a day will suffice to keep your levels consistent.

If you’re a newbie, start with 15mg per day, at the same time each day, for an 8-week cycle. More experienced users can take up to 25 mg per day. Although there isn’t much research to back up whether this is safe over time. Professionals advise against taking more than 30mg per day. The higher the dosage, the more side effects you may encounter.


The following is an example of a standard Ostarine cycle:

  • Take 15 mg daily for weeks 1 to 8
  • Post Cycle Therapy during weeks 9 to 12
  • Lastly, take a break from taking SARMs during weeks 12 to 16


It is generally recommended that users wait at least four weeks between SARMs cycles, and preferably even longer. The more time you give your body to recover and rebalance, the better.


Stacking numerous chemicals has the potential to be beneficial. However, it can also be quite harmful. Experts don’t recommend stacking Ostarine because it is so new and there isn’t much evidence on it.

When you add another chemical to the mix, you’re also raising the risk of negative effects. Therefore, it’s always best to start with one component. Then, gradually increase your dosage before adding another.


Ostarine is a low-dose SARM with muscle-building and performance-enhancing properties. Bodybuilders take MK-2866 to gain muscle. It’s so popular since it has nearly no adverse effects.

If you do decide to take Ostarine for bodybuilding, make sure you obtain it from a reputable source, which is 99 percent pure and third-party validated.

Always use a post-cycle therapy after every SARMs cycle. Most importantly, keep track of your blood work to ensure your safety.
