MK-2866: Mind-Blowing Facts About Ostarine

MK-2866 (Ostarine) is a selective androgen receptor modulator (SARM). The compound was developed by a Memphis pharmaceutical company called GTx INC.

The SARM, which is also known as Enobosarm and GTx-024, is currently being researched for its ability to help prevent muscle loss, muscle wasting, and overall dystrophy.

These conditions are often bought on by cancer and can have debilitating effects on one’s life.

The clinical trials conducted on this SARM show it to be very effective for all the above-mentioned purposes.

The results are so promising its been introduced to the bodybuilding community as an effective measure against muscle loss and wasting. Interest in the drug grew to the point that tons of self-published literature was introduced to show its effects, usage and more.

What Makes Ostarine So Special?

Anecdotal evidence shows that MK-2866 is one of the safest and most effective anabolic SARMs on the market.

It works similarly to testosterone but without any of the adverse side effects like messing with the natural test production.


Instead, this SARM focuses on increasing natural androgenic activity in bone tissues and muscle.

When taken in conjunction with a strict training regime and a balanced healthy diet, MK-2866 can have similar effects to a cycle of Dianabol or Test-E but without any of the negative side effects.

It doesn’t have any effect on the prostate, the liver or the brain. It can be slightly suppressive, but we will discuss that later in this article.

However, it’s important to be absolutely sure that you have purchased real Ostarine. Fake products might end up giving unwanted side effects. This is why you should buy from a reputable vendor like Sarms4You.

Ostarine Benefits

The following information is a summary of the available clinical and scientific data on the effectiveness of Ostarine on fighting and/or preventing muscle-wasting.

Increases Muscle Mass and Boosts Strength

Research is on-going to determine the effects of Ostarine on cancer patients and elderly persons that experience muscle loss and muscular dystrophy.

For instance, a clinical trial with MK-2866 was conducted with a healthy group of 120 elderly individuals who were given 3mg of Ostarine per day for 12 weeks.

MK-2866 Benefits

At the end of the trial, the individuals experienced improved fitness and more lean muscle mass than before. The group that was given 3mg gained a total of 1.3kg lean body mass (2.8 lbs).

The most notable fact was that they also lost 0.6kg (0,3 lbs) fat mass whilst on OstarineSo they gained muscle and lost fat.

At the end of the trial, the individuals experienced improved fitness and more lean muscle mass than before. The group that was given 3mg gained a total of 1,3kg lean body mass (2.8 LBS).

It’s important to note here that no steroid-like side-effects or risks were observed, and MK-2866 only works when taken in the mentioned dosage, while lower doses don’t show the same effects.

In another clinical trial, 159 cancer patients were split into two groups, with one given 1mg of MK-2866 and another 3mg of MK-2866 per day for 4 months.

At the end of the trial period, both groups showed increased lean muscle mass without any adverse side effects. 

In yet another study, rats that were given MK-2866 orally showed that the body easily assimilates and distributes this SARM. Results also showed that it’s quickly eliminated through detox pathways.

With that said, large-scale studies have yet to be conducted to show the effects on MK-2866 on cancer patients that are experiencing muscle loss.

Helps with Bone Health

It’s common to experience poor bone health as we age due to the deterioration of bone-protective sex hormones in the body.

This often leads to conditions like osteoporosis and other bone diseases. One way to fight such deterioration is to improve bone mineralization and increase muscle mass.

The latter is even more important because muscle mass plays a huge role in strengthening the skeletal system and improving bone strength.

Ostarine has a whole host of benefits to offer including the prevention of bone diseases and promoting speedy recovery from bone fractures.

However, these claims about MK-2866 are supported only by animal studies and there are no human studies to corroborate them.

Protects Heart Health

A clinical study involving 120 healthy subjects of advanced age showed that Ostarine can help lower bad HDL cholesterol levels as well as blood fats like triglycerides.

These results were based on a daily dosage of 1 to 3mg per day which helped to maintain healthy lipid levels.

This is crucial for the prevention of heart disease, and these results show us that Ostarine may be a good idea for heart disease sufferers who are dealing with muscle wasting.

Increases Insulin Resistance

Based on the same study mentioned above, Enobosarm can lower blood glucose and increase insulin resistance. These are the same effects that anti-diabetic drugs like metformin show.

Additional research is required to prove the benefits of Enobosarm on metabolic syndrome and diabetes but the data is promising.

Ostarine Cycle

Once you’ve made up your mind about running a cycle with this SARM, it’s important to know that a typical cycle lasts between 8 to 12 weeks.

Take a look at the following ostarine cycle..


You’ll see most people experiment with it for at least 6 weeks minimum. In my opinion, this is a short cycle but can still be effective.

My cycles with this compound have all been at least 8 weeks because it takes a while for the effects to build up. Especially for a bulk I would consider running it for longer.

Keep in mind this is a simple example based on anecdotal experiences. You’ll find that a lot of users stack it with other SARMs and they might run different dosages.

Let’s move onto the dosage information.

Ostarine Dosage Information

There is no one size fits all approach when it comes to the usage of MK-2866. Some bodybuilders prefer to use it on its own for purposes of body re-composition, while others like to stack SARMs.

For example, the triple stack is a combination of MK2866, Andarine and Cardarine.

MK-2668 has been compared to juicing because of its effectiveness at simultaneously increasing lean muscle mass, strength and fat burning. It’s a triple threat whose effects can be observed on daily dosages of 10 mg to 30 mg taken for 12 weeks.

This SARM has a half-life of 24 hours which means you only need to take one dose a day for the best results.

Personally, I would take it every morning when I wake up. Since it’s got a long half life it doesn’t really matter when you take it as long as you don’t forget your daily dosage.

Ostarine Results

It’s not uncommon to experience 5 to 10bs of muscle gains on Ostarine, but it’s possible to do even better when you pair the SARM with a strict diet.

Your results can go two ways, you can choose to bulk up or you can let Ostarine help you get shredded.

A lot of bodybuilders prefer to use Ostarine during the cutting phase because of its superior muscle protective abilities.

To get the most out of it though, you need to use up more calories than you consume.

Make sure to eat a protein-rich diet to help maintain lean muscle mass, prevent calorie deficit and maintain a high metabolism. When you combine this strategy with high-intensity interval training (HIIT) you’ll constantly burn fat and achieve your goals faster.

Ostarine Results

However, it’s important to avoid getting a low metabolism as that will make it doubly hard to burn fat.

At the end of the day, you want to protect your metabolism and muscle mass as much as you can during the cutting phase. 

Now, if you’re planning to get muscle gains and strength results you should consider bulking with this compound.

Research shows that taking just 1 to 2 mg of Ostarine for 12 weeks can increase lean muscle mass by 3 lbs. without maintaining a strict exercise or diet regime. Imagine what it can do at 20 to 30mg per day.

This shows that MK-2866 can increase lean muscle mass on its own without any dietary changes.

For the best results during the bulking phase, it’s recommended to take this SARM in dosages of 20mg to 30mg per day for at least 8 weeks.

If you’re experienced you can consider extending the cycle for optimal results.

Ostarine Before And After

You’ll find many before and after pictures online. When this compound is used correctly, you can expect drastic results. 

As I previously mentioned, it can be used for gaining size and strength in a bulk, but also during a cut.

Take a look at the following picture, this guy managed to recomp. He basically managed to lose bodyfat whilst adding a solid amount of muscle.

These are pretty standard results that people get with the help of this SARM.

It’s also pretty obvious that his strength also increased by the looks of this before and after image. Ostarine is great for holding onto lean muscle mass and potentially building some when diet is in check.

Keep in mind that it’s also imporant to eat enough nutrients and to train heavy.

My Ostarine Review

When I used MK-2866 (Ostarine) for my bulking cycle I gained a significant amount of muscle.

I didn’t use a lot, because I wanted to test out what the effects were of this compound. So I stuck by 20mg a day for 12 weeks total.

I ended my cycle with a PCT Supplement called Rebirth PCT, which recovered me quite well. 

The things I noticed instantly was increased endurance and drive in the gym. All my exercises were done very easy and I could do much more sets than normal.

I also noticed an increase in vascularity, even when I was in a bulking stage.

At the end of my cycle, I gained a solid 5-6kg (13 lbs).

In my opinion, Ostarine is a good compound for gaining lean muscle and preserving muscle. But, there are better compounds like LGD-4033 or RAD-140 for muscle mass

Using MK-2866 to Treat Injuries

Injuries are an unavoidable aspect of training and often happen as a result of using the wrong training methods, having an improper recovery routine, and/or overtraining.

That’s why it’s so important to keep the structure of the joints protected, and you can do this by strengthening the tendons and ligaments and maintaining proper form while lifting.

This will help you continue training hard and challenging yourself without running into unnecessary injuries.

Thanks to its bone-strengthening properties, MK-2866 has been used to heal osteoporosis and even prevent injuries.

The most beneficial dosage of Ostarine to take when treating injuries is 12.5 mg per day. Some researchers will also combine it with Ibutamoren.


MK-2866 works great when used in conjunction with a strict dieting regime, as it helps increase muscle mass while promoting proper strength maintenance.

The best way to enhance fat loss and muscle mass is to cycle MK-2866 with another SARM like GW-501516 (Cardarine) during the cutting phase.

This will help increase cardiovascular endurance in order to enhance results.

To achieve this, it’s recommended to take daily dosages of 20mg of GW-501516 and 25mg of MK-2866 together during the cutting phase.

Experienced users will also add in Andarine as well. When these three compounds are stacked they become the Triple Stack. This is an extremely common stack for bodybuilders that are cutting.

Ostarine Side Effects

So far, research shows that Ostarine (MK-2866) doesn’t come with any side-effects.

That’s because it doesn’t have an estrogenic nature. No user or study has reported any health issues either like bloating, water retention, liver toxicity, prostate problems, high blood pressure or cardiovascular issues.

However, anecdotal evidence suggests that taking MK-2866 in high dosages for 8 to 12 weeks can lead to lowered testosterone levels.

The good news is that this effect is only temporary and testosterone levels should get back to normal 3 to 4 weeks after stopping the intake of the SARM.

You should consider using a PCT supplement like Rebirth PCT to help you recover from the cycle. They consist of ingredients that could potentially increase hormone levels.

It’s also worth mentioning that you should be cautious when buying this product. I’ve seen people get side effects when they purchased fake sarms.

Make sure to buy from Sarms4You as they are the most reliable vendor.
