(a.k.a. Ostarine and MK-2866)


What Ostarine does is bind to the Androgen receptors within the body.

You’ll mostly find the receptors within bones and muscles. Because Ostamuscle is a ‘’selective’’androgen receptor modulator, you will barely experience any side effects. If you didn’t know, SARMs selectively target the androgen receptors without interfering with any other processes.

The two main things Ostarine is known for is building muscle and burning fat.

It’s even able to help you build muscle whilst burning significant amounts of fat. Trust me, there is no compound like MK-2866. Let’s have a closer look at both of these ostarine benefits.


Because Ostarine was created to help combat muscle wasting diseases, it has great muscle building abilities.

Most people think Enobosarm (MK-2866) can only be used when cutting bodyfat, that is not true.

There’s plenty of people that use this SARM to pack on serious amounts of muscle mass. The muscle building effects of Ostarine have also been backed up by multiple clinical studies.

Of course, you won’t be gaining exactly the same amount of muscle just like with steroids such Trenbolone. But it’s worth mentioning that your progress won’t be limited by side effects. This will allow you to progressively make gains without any issues.


Besides being a great muscle builder, MK2866 is also really good at assisting with burning fat. When you are in a caloric deficit, you will most definitely be losing muscle mass. Obviously, this is something you don’t want to happen.

This is where Ostamuscle steps in. Because it has such great muscle preserving abilities it will make sure you won’t lose a single bit of muscle during a cut. Because you will be holding onto more muscle, you will be able to diet more effectively. Your strength will also not take a huge beating, unlike when dieting naturally.



The best Ostarine dosage seems to be anywhere from 20 to 30mg per day.

Of course, this Ostarine dosage is based on anecdotal experiences. Most users seem to take at least 20mg of Osta per day in order to achieve the best results.

Ostarine Results

At an ostarine dosage of 20 to 30 milligram per day, you can expect to experience all the benefits previously mentioned. For cutting, a lot of people seem to take anywhere from 15 to 20mg per day. For bulking it’s usually around 30mg.

Due to Ostamuscle being quite a mild SARM, it’s not really effective at low dosages. For example, 5mg of YK11 is known for giving insane results whilst 5mg of MK-2866 won’t do anything at all.  Of course, you don’t want to be taking too much but based on the research I have done 20-30mg seems to be the sweet spot for most.


The ostarine cycle should be based on your personal goals. From what I have seen, most ostarine cycles seem to last anywhere from 8 to 12 weeks. You should not run this compound for more than 12 weeks because you will greatly increase the chance of suppression.

Take a look at these cycle examples.

Ostarine Cycle

These options are the most frequent types of ostarine cycles you will find online. The first cycle is for beginners because the dosage is quite low and the cycle length is only 8 weeks. If you are more experienced you could go with either the second cycle or the third cycle.

My ostarine cycle lasted 12 weeks and that felt like the sweet spot. I was able to lose a good amount of fat whilst gaining a few lbs of lean muscle.
MK-2866 usually kicks in around the second week so make sure to keep that in mind.


With this SARM you can expect to gain anywhere from 4 to 6 lbs of lean muscle mass. It’s not as strong as the other selective androgen receptor modulators (SARMs).

It can also significantly increase strength during a bulk. When you are cutting, this compound will make sure you hold onto your muscle mass.

Some researchers will also stack SARMs. One popular stack is the Triple SARMs stack.

It includes Andarine, Cardarine and Ostarine. It’s said to be highly effective during both cutting and bulking.


The thing that is really great about Osta is that it can be used for multiple purposes. You will see people use it for both cutting and bulking. I have seen some amazing ostarine before and after pictures online. The following image is what a typical Ostarine before and after looks like:

These are very impressive results. As the image shows this person was able to pack on a serious amount of mass within a short period of time. He took MK-2866 for 8 weeks dosed at 20mg a day.

You can also see that he managed to lose some extra body fat as well. Basically, he gained muscle whilst losing fat. In his forum posts he also mentions that his strength went up significantly.

If you are looking to obtain a similar ostarine before and after I would suggest you get your diet and workout program in check.

If you’re looking to help treat injury, try stacking with MK677 (Ibutamoren).


A commonly asked question is, does Ostarine have side effects? The answer is simple, you should not be experiencing any severe side effects from MK-2866.

The only two common side effects caused by Ostarine in the clinical studies are headaches and back pain.

Some users also report experiencing lethargy which might be due to suppression. Most will recover just fine after a cycle of Osta.

When you take more than the recommended dosage of MK-2866 you can start to have side effects. This is why the maximum dosage of Ostamuscle is roughly 30mg a day. It is advised to stay within the dosage guidelines.

Keep in mind that MK-2866 is the mildest SARM. You should not get any negative effects from using it. If you do however think that the MK-2866 is causing problems than you have should double check if your supplier is legitimate.


For those of you that think SARMs can’t cause gyno, it’s not true. Yes, the chance to get gyno with osta is very small but it’s still possible. 9 Out of 10 times, Ostarine will not cause gyno.

There are exceptions for people who are very prone to gyno. Besides that, most people seem to experience gyno symptoms at redicously high dosages of Osta. Don’t go over 20-30mg and you should be just fine.

If you are confident you are developing gyno make sure to immediately get on an Aromatise Inhibitor such as Arimidex. It’s easily available over the counter and should be sufficient to help lower estrogen levels.

With that being said, some people are EXTREMELY paranoid about Ostarine causing gyno. They will start playing with their nipples all day thinking they are ‘’sensitive’’ and they are developing a lump. Almost each and every one of them will eventually say that it was all between their ears once the cycle is over.

Don’t fool yourselves, there is a VERY small chance of developing gyno from Osta.


In most cases, MK2866 does not require a SARMs PCT.  Ostamuscle barely has any impact on your natural testosterone production. Keep in mind that the dosage and cycle length will also play a role in wether you will need a PCT or not.

Personally I did not need a PCT for my 12 week cycle of Ostamuscle. I also did not feel any signs of suppression afterwards. The dosage was roughly 30mg a day and I felt great after the cycle which means I recovered just fine.

I have seen instances where people did require a PCT with Ostamuscle. They experienced low testosterone symptoms which means they required a Post cycle therapy. A good PCT protocol will help recover the body’s natural hormone production. Often Nolvadex or Clomid is used.

You might also want to consider purchasing a testosterone booster that contains Ashwagandha and other herbs. Most Test boosters actually contain herbs that have been proven to raise testosterone levels.

For SARMs such as YK-11 and RAD-140 you will require a PCT because both are known to be extremely strong and suppressive.
