Ostarine (MK-2866) is a SARM developed by GTx for the prevention and treatment of muscle wasting. It may eventually become a medical prescription to prevent cachexia, atrophy and muscle loss, and hormone or testosterone replacement therapy.

As a research chemical, Ostarine belongs to a class of chemicals known as SARMS or selective androgen receptor modulators. SARMS produces selective anabolic activity in certain androgen receptors. The advantage of SARMS compared to testosterone and other anabolic steroids is that they do not have androgen activity in non-skeletal muscle tissue. Ostarine effectively maintains and increases lean body weight.

How Ostarine (MK-2866) WORKS?

Ostarine (MK-2866) binds to the androgen receptors just like anabolic steroids do, but it does this selectively, which means that it has considerably less side effects.


A 12-week, double-blind, placebo-controlled Phase II clinical trial of ostarine showed that ostarine increased lean muscle mass and improved body function without negative side effects of testosterone or other anabolic steroids.


Ostarine (MK-2866) is mainly used for the treatment of muscle wasting and osteoporosis. Nevertheless, it retains nitrogen and strengthens the joint. Therefore, in terms of health benefits, this is a very versatile compound.


Lean muscle gains (bulking)

Ostarine (MK-2866) is the most synthetic metabolite of any SARMS, which is first used to get lean muscle. The total weight of the growth can not be similar to the expansion of steroids, but the total income is almost completely thin muscle.

Ostarine's earnings are very conservative, and users generally see an increase of up to 7 pounds. Of lean body weight over 8 weeks cycle 25mg day (diet dependent). The most common dose is 25 mg for 8 weeks. The side effects of using steroids do not occur in the cycle.

In general, ostarine, the higher the dose, the more inhibition. Although the inhibition is minimal and has nothing to do with the inhibition of steroids, it takes 3 weeks for any cycle of ostarine over a four-week period. There is no specification in this pct.

Losing Bodyfat (cutting)

● Ostarine would primarily fit into a cutting protocol for the maintenance of muscle mass while reducing calories.

● As Ostarine has anabolic effects, the dieter can cut calories without having to worry about muscle or strength loss.

● Ostarine has also shown noticeable nutrient partitioning effects among users, another reason why it can be of great help when cutting.

● A 15-20 mg dosing protocol for 6-8 weeks is good for cutting with Ostarine without undergoing any side effects or high suppression. However it must be stated that due to the lack of androgenicity, muscle hardness and overall results are not as prominent as with the SARM S-4.


Recomping is ostarine really shining place. At the same time lose fat and get the recommended effect of muscle is the majority of users are looking for. Trying to achieve this when you are not absolutely new to the training is very difficult.

Ostarine is looking for a reassembly where the benefits are nutrient distribution. Calories are removed from the fat store, calorie intake is fed to muscle tissue.

Dosing regimen for 20-25mg, 6-8 weeks will give excellent compensation effect.

Injury Prevention

Ostarine's role in the synthesis of bone and skeletal muscle tissue in the synthesis of metabolism, which means that it can be used for a variety of purposes, such as osteoporosis and as a simultaneous use of drugs to reduce bone density for treatment. Therefore, it is used as a complex for rehabilitation injury, especially bone and tendon injury has a great application.

Recommended daily dose of 12.5mg for this purpose, and to improve the joint movement, just 6-8 days to see.


Depending on the objectives, there are a few ways to stack Ostarine:

Endurance: You can stack ostarine with cardarine for increased endurance before your workout or run.

Anabolic steroid stack: Ostarine can be added to your existing anabolic steroid cycle in order to

increase lean muscle mass and strength without additional side effects.

During PCT or bridge: Ostarine is minimally suppressive at 25mg per day for 4 weeks or less. Thus, it can be stacked into your post cycle therapy, or your bridging phase, to maintain strength and muscle.

SARMs triple stack: If you want to recomp (build muscle mass while losing fat at the same time), Ostarine stacks beautifully with andarine and cardarine.


Ostarine's half-life is very strong for 24 hours, so only one dose is needed every day.

The liquid form should be shaken, sprayed into the mouth, swallowed immediately. It is also recommended to chase with some juice or water. In addition, it is important not to put ostarine under the tongue or to mix the liquid in the cup, otherwise it may be lost.

The dose of Ostarine (MK-2866) is usually between 12.5 and 50 mg per day. The lower dose is suitable for those who wish to use its therapeutic capacity, while the higher dose is more of the reconstructed and muscle mass increases.
