What is MK–2866 or Ostarine? Benefits and Drawbacks


Ostarine or MK-2866 is a substance that is often mentioned within bodybuilding and fitness circles. Alternatively, people call it Enobosarm, and it is one of the most common SARM products in the world.

SARM stands for selective androgen receptor modulators. It is a product group that is meant to burn your fat while helping you build muscles. Although the substance has been around for decades, we just recently started using it.

In fact, it was licensed way back in 1997. Keep in mind that Ostarine is still under clinical research, and there is a lot more we can learn about it.

What are the main features of MK-2866?

There are lots of reasons why you should try this muscle-building item. Of course, there are also a few drawbacks that you need to consider beforehand:

Potential benefits of using MK-2866

  • It increases your muscle mass and bone density
  • Unlike some other products, you can achieve great results in a short amount of time
  • While the product is still being researched, there is a lot of data backing up its efficiency
  • You can use it for quick fat loss and faster recovery time during a training cycle

Potential drawbacks of using MK-2866

  • Although MK-2866 is less volatile than steroids, it can still cause certain side effects
  • MK-2866 is licensed but still not approved by the FDA and other regulatory organizations in the world
  • We don’t know much about the potential long-term effects

A lot of experts regard Ostarine as a safe product. But, the studies are still not conclusive. This is especially true when talking about long-term effects.

This is why you’re taking it at your own responsibility. Still, the substance has shown a lot of promise during the clinical trials, and if you use it correctly, you should increase your muscle mass within weeks.

The legal side of Ostarine

Before you buy Ostarine or any other SARM, you have to get acquainted with the legal ramifications of buying and using the product. As already mentioned, the substance is not sanctioned by the FDA.

It is also illegal, according to the World Anti-Doping Agency. So, if you’re an athlete who wants to improve his results, we suggest that you avoid it altogether.

But, while there are certain restrictions in place, that doesn’t mean that MK-2866 illegal. You can buy it online from our web store, and no one will ask you any questions.

Most people use it to gain lean muscle mass or to improve their athletic performance. Ostarine may also be used for certain medical conditions such as muscle wasting.

When buying the product, it is very important to purchase it from a legit source. Given that this is an illicit substance, according to the FDA and other regulatory organizations, there will be a lot of resellers who will try to sell you bogus items.

So, make sure to check the online reviews before buying it. A lot of companies rely on 3rd party laboratories to attest to the quality.

But, that doesn’t mean that a SARM reseller is bad if they don’t provide these results. It is just one additional layer of security.

How does MK-2866 work?

Generally speaking, most SARMs work in a similar way.

When talking about Ostarine in particular, this substance works by binding itself to androgen receptors. By stimulating these receptors, the body will start “working” on the muscles leading to rapid muscle growth and repair.

Ostarine starts working pretty quickly after you introduce it into the body. However, you need to complete the full cycle in order to get the necessary results.

The most important feature of Ostarine is that it provides results very similar to steroids, but without aromatization.

What is the difference between MK-2866 and steroids?

Although we’re not certain regarding long-term effects, we do have a lot of data regarding short term-effects of Ostarine.

According to the users, you can gain anywhere between 10 to 15 pounds of muscle when using the product. But, what makes it so good is that you’re also losing fat in the process.

Ostarine has a very different impact on your body compared to steroids. Most people complain about steroids because of their potential for causing cancer. This doesn’t happen when you’re using MK-2866.

The substance doesn’t have the same volatile impact on your prostate, which would allow you to focus on your training without having to think about the potential problems.

If we had to summarize the potential benefits to your body, we could say that Ostarine causes rapid muscle growth, accelerated loss of fats, improvements to bone density, and improved athletic results.

How to use Ostarine?

If you had experience with steroids or other SARMs, you shouldn’t have a lot of trouble using Ostarine. The common dosage is somewhere between 10 to 25mg.

In some cases, you can ramp it up all the way to 50mg. However, you probably won’t need that much as 10 to 25mg dosage works just fine.

Of course, higher dosages require precautionary measures. You will get much better results if you go with 25mg, but you will also have to be careful if you decide to do so.

Another issue is the lack of data regarding the potential long-term effects. We have some information about its short-term impact.

But, most of these studies were performed with a low dosage. According to some of them, you can use just 3mg of the substance, and you should still achieve good results.

The recommended dosage for bodybuilders

If you’re a bodybuilder, you should consider going with a 15mg dosage. It isn’t uncommon for people to take 25 and even 50mg, though.

Nevertheless, if this is your first time taking SARMs or steroids, we suggest that you start with a smaller dosage. Even 10-15mg should suffice.

Make sure to take the same dosage each day, and at the same time. This should be done over an 8-week cycle. Some people take it during a 12-week cycle, so there is some wiggle room.

In the end, it all depends on the results that you want to achieve. Naturally, you can also start with a smaller dosage and ramp it up as you.

No matter what, we suggest that you consult someone who has experience before starting the whole process.

Here is our recommended cycle:

  • During weeks 1 through 8, you should take 15mg each day
  • During weeks 9 through 12, you should perform a post cycle therapy
  • During weeks 12 to 16, you should take a break from MK-2866

It is much better if you have a break of 4 weeks between the cycles. Some people go for even longer breaks than that. Keep in mind that the recovery is every bit as important as the therapy, so don’t rush things!

Stacking Ostarine with other SARMs

You also have the option of stacking MK-2866 with other SARMs. This would boost the overall effect leading to more muscle mass, more fat burning, and generally, better athletic results.

Recommended bulking stack:

  • 15mg Ostarine
  • 15 mg Ligandrol
  • 25mg Ibutamoren

The stack should be taken once per day, during an 8 to 12 weeks’ period. You need to follow it up with PCT.

Recommended cutting stack:

  • 15mg Ostarine
  • 50mg Andarine
  • 10mg Cardarine

Again, this cycle is taken during the same 8 to 12-week period. It should help you burn fat.

Potential side effects

We should also analyze the potential side effects. As already mentioned, side effects are not that volatile as with steroids. This is precisely why, nowadays, people prefer SARMs to steroids.

Here are some of the issues you might encounter:

  • Back and joint pain
  • Increased appetite
  • Decreased HDL

These are the most common side effects that the users have reported. Most of them are manageable.

Unfortunately, we still don’t have enough data regarding potential long-term issues. So, you will have to take MK-2866 (Ostarine) at your own risk.
