Ostarine (MK 2866): Our Thoughts on This SARM


If you’ve been serious about the gym life, then you’re probably a lot like me. I’m always looking for ways to improve my physique without using steroids or other dangerous methods.

Something that recently caught my eye was an article talking about SARMs. SARMs are similar to anabolic steroids, but they don’t possess a lot of the terrible side effects.

One of the most popular SARMs out there is Ostarine, also known as MK 2866. Today we’re going to talk about how it works, where to buy it, and what results you can expect if you take it.

I do need to give a disclaimer before we jump in. Always speak with your physician before starting any supplement, especially ostarine. Be sure to get blood work done frequently and discontinue use if you experience any side effects.

Benefits of Taking Ostarine

The main reason people take ostarine is to increase muscle mass. Athletes will experience big increases of lean tissue, along with a decrease of body fat.

Many people consider ostarine to be the “gold standard” of SARMs. Ostarine is:

  • Highly anabolic, even in low doses
  • Great for muscular endurance
  • Minimal side effects
  • The ability to repair tendons and joints.

People taking ostarine will undoubtedly see a better physique, and as long as you use it responsibly, side effect free.

Ostarine can easily be incorporated for a bulking cycle. Adjust your calories to +1000 TDEE and you will have no problems packing on a great deal of muscle mass. A typical bulking cycle using mk 2866 will last around 8 weeks.

Users can expect to put on 10lbs of muscle over 8 weeks as long as diet and nutrition is in check. People who are new to working out typically get quicker, more drastic gains.


Most people end up using ostarine for a cutting cycle. MK 2866 is fantastic for this. The problem most people face when cutting is losing muscle mass.

Ostarine prevents the body from going into a muscle wasting state. In fact, GTx (the company who created it) specifically studied MK2866 for this purpose. There are many studies showing the ostarine is effective for a cut.

While someone who is not taking SARMs would certainly lose muscle with a -1000 caloric deficit, such is not the case here. As long as you give ostarine enough time to build up in your body, you should have no issue with a -1000 deficit. I’ve seen people go on 500 calorie a day diets and not lose an ounce of muscle thanks to this sarm.


If you’re looking to stay the same weight while increasing muscle and losing fat, then you’re in luck. You will find that using MK-2866 will help you recomp better than most other supplements and products out there. For all recomps, I suggest adding a decent amount of cardio and working with a high protein diet.

Don’t fear carbohydrates, as your body will need them to repair muscles after workouts.

Ostarine Dosage Guide

No matter what some other people say, you should always keep your dose of ostarine at 20mg per day. If you go higher, you are much more likely to experience side effects.

You might actually find that a lower dose is just as beneficial as well. When using SARMs, you always want to be using the lowest effective dose possible. Going higher than your body needs is a surefire way to experience side effects.


I suggest taking ostarine twice per day. 10mg in the morning, and 10mg at night. Doing your dosing this way ensures that your body is getting a steady supply, and your blood plasma levels stay nearly the same.

Side Effects

Ostarine does carry some side effects if you’re not careful. These are mainly experienced by people who take larger doses than they should. Some of these side effects include:

  • Low testosterone
  • Low LH
  • Low FSH
  • Lowered sex drive
  • Lowered energy levels

Again, this is not meant to scare you. The people who get these kind of side effects are usually taking 3-5x the recommended dose. As long as you keep your dosage around 20mg a day max, you will be fine.

Where to Buy Ostarine Online

If you think you’re ready to purchase a cycle of ostarine, then there are some things you should know.

Number one: SARMs get faked. A lot.

These are not the cheapest compounds to source, so a lot of sketchy retailers have been known to spike their products with prohormones. Some even add steroids to their products. This is obviously not what you want.

We went through a lot of companies before deciding on a recommendation. At the end of the day, we found that Proven Peptides offered the best value. The main thing is that they have published lab tests available for customers to view.

What Results Can You Expect

Depending on how clean your diet is, and what kind of training routine you use, you can expect the following:

For Bulking: Gains of 10lbs over 8 weeks are common.

For Cutting: Keep your muscle while losing 5-10lbs over 8 weeks. This will vary depending on how many calories you’re cutting.

For Recomping: Gainst of 2-5lbs of muscle, along with losing 2-5lbs of fat are common.

Final Ostarine Review and Conclusion

In conclusion, you will see great results with this sarm as long as you follow a proper diet. Training and eating clean are the building blocks to success, but mk2866 can help multiply those results.

We recommend ostarine over the other sarms due to it being very low side effect and inexpensive. If you’re ready to take your training to the next level, give it a shot.

Ostarine FAQ

We’ve been getting a lot of questions asked about this sarm, so we’ve made a list of some commonly asked questions. If you have any more, just comment below and we will update the post.

What PCT to use

You won’t need a PCT as long as you keep your cycles under 8 weeks. While it is true that mk-2866 can temporarily lower testosterone, it doesn’t effect LH/FSH so you will not need a PCT drug.

Can I Stack Ostarine?

Yes, you can absolutely stack it with other sarms or supplements. Just don’t overdue it when stacking with sarms. If you are on TRT, ostarine makes a fantastic addition to your weekly injections.

Does ostarine Cause Hair Loss?

There have been no studies done showing whether or not this happens. However, we know that MK2866 does not raise levels of DHT in the body, so hair loss should not be common.

Can Ostarine Cause Gyno?

Not likely. If you get gyno, chances are your sarms are tainted with either prohormones or actual steroids.

What is the Half Life of Ostarine?

The calculated half life of ostarine is around 24 hours.
