To be an athlete, or a competitor in any sport or physically demanding pastime, you need to be the very best version of yourself that you can be.

To perform at a professional level requires a huge amount of dedication, motivation, and hard work!

But what about when the only competition you are up against is yourself?

Well, in that instance, you can do whatever you deem necessary to succeed.

If your goal is to build muscle and build a physique that would make a Greek God jealous, you know that your first port of call should be the gym.

After that, it should be the kitchen, but what next? Well, if you train naturally then that’s about it.

If however, you have been tempted to cross over to the “dark side” and to use steroids and PEDs (Performance Enhancing Drugs).

You may then begin to start looking at viable cycles and stacks.

Today we’re looking at what is Ostarine (MK-2866) as we will be looking at what it is, how it works, why people use it, how to use it, potential side effects, and much more besides.

So, without any further delay, let us now learn more about Ostarine cycle.

Legal Disclaimer

Steroids and SARMs are dangerous.

In fact, they are potentially fatal.

We, therefore, cannot condone their use nor recommend their use to any of our readers.

There’s also the fact that the majority of them are illegal, so by purchasing them, you could technically be breaking the law.

With that said, however, we also know that people have used steroids and SARMs for decades, despite knowing the risks and dangers.

The aim of the content we create is not to encourage steroid use, but rather to inform readers on how to go about using them safely.

If people are going to be using these drugs anyways, we’d much rather that they did so safely.

What Is Ostarine (MK-2866)?

So, as you are here, you’re more than likely looking to read up on the potential bodybuilding and performance-enhancing benefits of steroids, SARMS, and other similar compounds.

Well, in today’s article, we’re going to be looking at Ostarine.

Ostarine (MK-2866) is, without a doubt, one of the best and most popular SARMS on the black market today.

SARMS are Selective Androgen Receptor Modulators that, although being able to provide similar benefits to steroids, are still not the same as steroids.

Over the years, SARMS such as Testolone and now Ostarine, have increased in popularity exponentially.

Ostarine is a synthetic compound created by a Memphis pharmaceutical company named GTx Inc.

The compound is in its early stages but was created with the primary intention of helping to prevent muscular degeneration and wastage.

The compound underwent numerous clinical trials for medical purposes and the results were very positive.

In fact, results were so promising that the compound soon found its way into the world of bodybuilding.

Bodybuilders looking to beef up and increase their strength and power began using Ostarine and saw very impressive gains.

Not only has it yielded very impressive muscle gains, but it has also been found to be extremely safe as well.

It is considered by many to be the best SARM when it comes to mimicking the effects of testosterone in the body, so you can see why it’s so popular amongst meatheads all over the globe.

How Does Ostarine (MK-2866) Work?

Ostarine is a SARM.

SARMs work in virtually the same way as one another so explaining how they work is much easier than explaining how each unique individual steroid out there happens to work.

As the name suggests, SARMs work by targeting your body’s androgen receptors.

This, in turn, enables your body to synthesize more muscle proteins and to build more lean muscle mass as a result.

Basically, the effects mimic those of powerful steroids, with the added bonus of far fewer side effects and are much safer.

If you were to use a powerful steroid Deca Durabolin, you’d wind up building a heck of a lot of muscle because you were activating androgen receptors in your body.

One tell-tale sign of steroid use is large-sized traps and deltoids.

These parts of the anatomy are the first to respond to heavy training when using steroids because this is where you have a large percentage of androgen receptors in your body.

The benefit of using powerful roids is the fact that you build muscle.

The downside is the fact that you suffer negative side effects such as shrunken testicles, gynecomastia, heavy bloating, and unstable hormone levels.

With SARMS, the side effects are far less severe, as you will find out a little later on.

SARMs have an affinity for androgen receptors found in your muscles and your bones, which is great if you want to bulk up.

This is useful because they generally don’t bother with androgen receptors found in your major organs such as the liver.

This again makes them much safer.

Ostarine Benefits:

So, why would people choose to use Ostarine and other similar SARMs for that matter?

Actually, there are many reasons, including the following:

Boost Energy Levels

When you make a conscious decision to bulk up and improve your physique, you will often find that you really begin to lack energy because you are training so hard.

And often are in a caloric deficit if you’re looking to lose body fat.

Having no energy will not only affect your training, but it will also negatively affect your quality of life as well.

If you’re always tired you won’t want to do anything and if you don’t want to do anything your training will suck, as will your mental health.

Ostarine has been found to significantly increase your energy levels, making it ideal for times when you are really pushing yourself in the gym while training.

Great For Bulking And Cutting

It’s rare that you will find a steroid or SARM that is suitable for use during both a cutting cycle and a bulking cycle but with Ostarine, that is exactly what you get.

Ostarine is anabolic, which means that it will help to significantly increase your muscle mass and strength.

It, however, does not aromatize and does not convert to Estrogen-like steroids do, so it doesn’t cause bloating or water retention.

This is very important because bloating and holding water can cause your muscles to look flat and washed out, which is the last thing you want during a cut.

When cutting, ideally you want to burn fat and preserve lean muscle mass, while looking as dry and shredded as possible.

Ostarine promotes weight loss as it boosts the metabolism, while also helping to build muscle.

This, therefore, makes it perfect for people bulking or cutting.

Fat Burner!

As we just touched upon above, Ostarine helps to boost the metabolism, which in turn makes it much easier for you to burn fat, Exactly like Stenabolic.

This is because your metabolism takes calories, both from food and from stored body fat, and converts them into fuel for your body.

The faster your metabolism is, the more calories you will burn and the more weight you will lose.

As an added bonus, you will also have more energy to exercise, and the more energy you have the harder you can work, so the more calories you can burn.

It’s like a beautiful, non-vicious cycle and we love it.

Increase Bones Strength

Another advantage associated with Ostarine that people seem to constantly overlook is the fact that it has been found to strengthen the bones.

Ostarine helps to increase bone density and not only, it does appear that it also enables the bones to absorb more calcium from the foods and supplements that we consume.

This is vital because calcium is a mineral used to strengthen the bones and increase their size, so the more of this mineral your bones can absorb, the better.

Increase Strength

Ostarine is a very anabolic SARM that has an extremely positive effect on a person’s overall levels of strength and explosive power.

For those of you looking to increase your lifts in the gym and become stronger and more explosive, Ostarine is perfect.

While using it won’t suddenly transform you into the world’s strongest man overnight, after a few weeks you will notice significant increases in your overall levels of strength and power.

Whether you want to add pounds to your bench, smash a new deadlift PB, or simply max out on squats, if you use Ostarine you will certainly be in a much better position to be able to do precisely that.

With the right training, diet, and rest, users of this SARM will find themselves becoming slightly bigger and stronger by the day.

Some Other Benefits

As well as the benefits to a person’s physique and performance in the gym, a few other advantages of Ostarine are due to its ability to improve your cognitive health and wellness.

This means that the drug is very beneficial for the brain.

Not only does it help to improve your mental health and mood, but it will also help you to focus whilst training, which in turn will help you to perform better in the gym.

Because it is anabolic, some users have also reported significant improvements to their libidos.

For most guys, that is certainly not a bad thing.

Ostarine Cycle:

If you are now thinking of using Ostarine to improve your physique and athletic ability, one thing you need to understand is precisely how to use Ostarine to your advantage.

Here’s a look at a typical Ostarine Cycle.

12 Week SARM stack for cutting

  • Ostarine – 25mg per day
  • Ligandrol – 20mg per day
  • Cardarine – 20mg per day

Ostarine Dosage

As you can see from the above, you should aim to consume 25mg of Ostarine per day for 12 weeks, if you’re looking to cut and build lean muscle.

For beginners, you should aim for 15 – 20mg per day and run an 8-week cycle to see how you get on.

Ostarine Side Effects:

As we have already established earlier on in this article, Ostarine is far safer for you than androgenic anabolic steroids (AAS) but that does not mean that it is completely siding effect-free.

There are some potential side effects that users will need to be wary of, including:

Hair Growth

While this is nothing too concerning.

If you do like to stay well-groomed you will need to be aware of the fact that Ostarine does.

In fact, it causes excessive hair growth because of how it stimulates your androgen receptors.

Androgens are hormones responsible for the growth and development of sexual characteristics, including hair.

Body and pubic hair growth will likely increase if you use this compound, so just bear that in mind if you like to be completely hair-free.


Another side effect that users of this drug will have to be wary of is acne.

This is again due to the fluctuation of hormones in the body.

Basically, your body goes through similar conditions as it did when you went through puberty.

To minimize the risk of acne, exfoliate your face, keep your pores clean, and be sure to wash your face regularly.

Is PCT Required?

Some people choose to stack Ostarine with steroids.

If this is the case, then PCT (Post Cycle Therapy) will most definitely need to be performed.

If you are running low doses of the Ostarine cycle (1 – 3mg) then PCT is not needed.

For anything above that, typically 15mg – 25mg however, PCT should be run.

For optimal results, Nolvadex should be sufficient enough, providing you are not stacking the SARM with any other compounds.
