Product Description

MK-2866 also known as Enobosarm or Ostarine is a SARM (selective androgen receptor module) created by GTx to avoid and treat muscle wasting. The great thing about MK-2866 is that it's considered to be one of the safest and mildest SARMs, mainly due to many positive users experiences and human studies.

How does MK-2866 Work?

It's no secret that androgens increase skeletal muscle mass – that's the main physiological reason why men typically have more muscles than women. In one study on mice, Ostarine was as effective as the most influential androgen, dihydrotestosterone, at restoring the size of pelvic floor muscles. Muscles in the pelvic floor are especially rich in androgen receptors.

Ostarine could also activate muscle stem cells (satellite cells), which help remodel and regenerate muscles. Ostarine causes muscle growth in a similar way to steroids, but without the negative effects, you would typically experience like on the prostate or other secondary sexual organs.

Benefits of MK-2866

There are multiple benefits from using Ostarine which is a really great compound that can assist you.

1 Increase muscle mass and boost strength

Ostarine does not only help in preventing loss of muscle tissue but also helps you gain lean muscle mass. It works amazingly for you whether you want to lose body fat or gain muscle mass. And it does not lead to fat gain or water retention, unlike other steroids. This basically means that the results will be a bit slow but you can be sure that the muscles you gain lean muscles and not just packed water or fat.

2 Burning fat

Besides being a great muscle builder, MK-2866 is also really good at assisting with burning fat. Losing weight can be very difficult at times and exercise alone can not give you the results that you want to see. So adding this compound in your diet can be of great help.

3 Help with bone health

Since Ostarine mimics testosterone in the muscles and bones, it has the potential to prevent bone diseases. Animal studies confirmed that SARMs like Ostarine could increase both muscle and bone strength.

4 Protect heart health

Ostarine may also prove to be beneficial for people with heart disease, who often suffer from muscle wasting and weight loss. 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.

5 Increase insulin resistance

Based on the same study mentioned above, Enobosarm can lower blood glucose and increase insulin resistance. The effects are similar to standard anti-diabetic drugs such as metformin. Ostarine may benefit people with diabetes or metabolic syndrome with more research.

What's the Best Ostarine Dosages?

There is no one size fits all approach when it comes to the usage of MK-2866. The best Ostarine dosage would be roughly 20 to 30mg for about 6 weeks. You can choose to extend the cycle if you are making good progress, however that would be completely up to you. For cutting, a lot of people seem to take anywhere from 15 to 20mg per day. For bulking it's usually around 30mg.

The recommended cycle duration is 6-8 weeks and it is reported that the results start becoming visible in the 4th week of use.

Also, when your cycle is completed, make sure to take a 4 week break before starting the next round and take proper post cycle therapy meanwhile in order to recover from all the health damage.

Method of Stacking

Not only is Ostarine a fantastic stand-alone SARM, but it works great in a stack with other SARMs. The best way to enhance fat loss and muscle mass is to cycle MK-2866 with another SARM like GW501516 (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 GW501516 and 25mg of MK-2866 together during the cutting phase.

MK-2866 Potential Side-effects

With a proper dosage, there seems to be no presence of any side effects with Ostarine as it doesn't display any signs of being suppressive. However, long usage or higher dosage seem to make it slightly suppressive but not as serious as those side effects present in the usage of steroids. It is recommended to conduct a mini PCT after an Ostarine cycle.


MK-2866 is one of the most effective SARMs which has almost no side effects and can be used for both cutting and bulking. Ostarine is also considered to be one of the safest SARMs due to all the research available.

If you are looking for a SARM that gives good results with the least amount of side effects than Ostarine is definitely a great choice.
