Ostarine (MK2866): The Complete Guide to this SARM

An intro to Ostarine

Ostarine, also known as MK-2866, is one of the most popular SARMs in the market today. If you are familiar with different brands of SARMs, then you most probably have come across Astarine as it is one of the most widely used drugs, mostly because of its effectiveness and little to no side effects exhibited. In the past few years, SARMs such as Ostarine, Cardarine, and Ligandrol have been growing in popularity especially because these days, bodybuilders and athletes are going for the safer methods of enhancement as opposed to steroids. Thanks to the recent technological advancement, it is now possible for users to just take a few drops of these SARMs every morning and still harvest the benefits of the illegal steroids.

The power of MK2866 lies in its ability to increase the strength of the user, enhance their physical performance, and fat shredding properties that cannot be compared to any other. By the end of this review, you will have enough information so that you can make a very informed decision before starting an Ostarine cycle.


Ostarine was first developed by a pharmaceutical company known as GTx. It was specially created with the aim of treating muscle-related conditions such as osteoporosis. Bodybuilders and athletes however discovered that the compound also had amazing muscle preserving benefits which lead to its introduction I the market as an enhancement supplement. Another reason that leads to the wide use of this substance is that its users never recorded any nasty side effects as compared
to the numerous side effects that were recorded after using steroids and
prohormones. Ostarine didn’t undergo full development until the year 1990. It was later in the 90s that the commodity began gaining fame and popularity in the market with most of its customers being male bodybuilders and athletes. There was some attempt from several state governments to make Ostarine illegal, but this move was not successful, and people could still access the drug in the
black market. Recently, after the introduction of online shopping, the SARM is now readily available in several online stores, far from the reach of the long arm of the law.

How it works

Ostarine and any other SARM for that matter work by selectively activating some of the body’s androgen receptors, as opposed to steroids which can bind to any tissues in the body. This results in
an effect that is similar to the one experienced after using steroids but without the harsh side effects associated with the use of the later. According to clinical studies and research, MK2866 has a very high affinity for the bone and muscle androgen receptors. In simplified terms, this means that this
SARM promotes the growth of your muscle while at the same time giving you denser muscles, without tagging along with any undesirable results such as it is the case with the use of steroids.

Benefits of Ostarine

The fact that Ostarine is one of the most widely used SARM also means that it is also one of the most widely tested commodity. Based on various studies conducted on the drug, it has properties that enhance rapid muscle growth, while exhibiting almost zero side effects when consumed within the recommended dosages. This makes it any bodybuilder’s or fitness enthusiast best friend.

  • Ostarine has also been linked to promoting lean muscle development and an improved physical function as compared to going for pure exercises alone. It is also famed for being among the most isolated enhancement supplements available in the market today.
  • From other studies done, it has been proven that Ostarine is not only good for physical enhancement, but it has also been proven that the commodity helps the users to shed weight much faster, even when the user is not necessarily following any diet plan.
  • The benefits do not stop there. The most incredible part of it all is that all these benefits have been clinically tested and proven to be absolutely true and functional. Another study shows that Ostarine actually improves the overall function of the heart, and to some extent, it also leads to decreased cholesterol.
  • Using Ostarine also ensures that you do not lose a single muscle especially in the cutting phase because as we had seen before, one of the properties of the substance is that it has very good muscle preservation traits. Holding on to more muscles means that you will be able to digest better. Similarly, the energy boost you get from using Ostarine will give you better endurance, meaning that you will get to exercise more and for longer.
  • Although the rate at which you gain muscle through the use of MK2866 is not the same rate as when you are using steroids, the slow and gradual gains will work to your advantage because this way, you are not exposed to so many side effects that come with using steroids.


Ostarine dosages are based on anecdotal experiences. Most users seem to prefer taking 20mg on a daily basis for the best results. The thing that encourages users to take high doses of the substance is the fact that it does not have a lot of side effects and overdosing on it does not seem to be dangerous at all. The recommended dosage by the manufacturer is between 20mg to 30mg, where you will have the best chances of reaping all the benefits mentioned above. For the cutting phase, most users prefer to take high doses of 5 to 20 mg per day. Again, because Ostarine is a mild SARM, it will not be very effective if taken in small doses.

Ostarine cycles can either go for 6 to 20 weeks. This is so that the body gets enough time for the levels of testosterone to balance out. The cycle should not be extended for more than 12 weeks because the substance suppresses your normal free testosterone in the body. The effects of Ostarine usually kick in in the second week, and therefore if you see no results by then, you are probably taking a counterfeit drug

Side Effects of Ostarine

The most c0ommonly asked question is whether MK2866 has any side effects. Well, the answer is you should not experience any side effects, and in case of any, they should not be very severe. The most common side effect recorded by users is headaches and back pain. There are other users who reported feeling lethargic which might have been caused by suppression of the testosterone, which is as a result of overdosing on the substance. This is why sticking to the recommended dosage is always so important. The maximum dosage per day should not exceed 30mg. Ostarine is among the mildest SARM ever made. It should therefore not give you any trouble unless you already have an underlying problem or you have been stacking it with another SARM with similar ingredients, leading to an overdose. If you are still experiencing problems with the substance without overdosing or stacking it with another substance, then you are probably dealing with a counterfeit.

Does Ostarine require a post cycle therapy?

Under normal circumstances, using MK2866 does not necessarily require post cycle therapy. This is because the substance has very little effect on the testosterone levels in your body. The dosage and the length of your cycle will be the determinant of whether you will need a post cycle therapy. If you take the supplement for longer than the recommended duration, the chances are that you will interfere with the natural production of testosterone in your body, and this is what will make you go for the post cycle therapy.

The pricing

Trust me, purchasing any SARM online is like wading through a swamp filled with con artists, liars and flat out crooks. When it comes to this kind of products, you should be extra careful about what you are getting because 80% of the products labeled Ostarine, are total fakes. This is why there are a lot of complaints from customers about certain SARMs that do not work or produces no results. In most cases, these products are counterfeits. The price for a genuine bottle of Ostarine goes for around $50, averagely. This price varies depending on the site. Most sites offer free shipping, and you can also strike a good deal if you buy more than two months supply.

The bottom line is, Ostarine is among the most effective enhancement supplements available in the market. When used in the correct way, Ostarine will make up a very vital tool in your fitness and bodybuilding arsenal. In a few weeks, you should be able to record some seriously lean and dense muscles.
