Of all the commonly known SARMs, Ostarine is one of the most used, and the most talked about. With the compound gaining increasing attention, it is important for people to know what the organic compound is all about. In case you walk into a store or lab, and you find a bottle labeled “Ostarine” or you hear people talking about it, this review will give you a broad insight into what MK-2866 is.

In this Ostarine review, we will be talking about what ostarine is essentially, the benefits of ostarine, what to expect when you use it, the dosage information to know when you consider getting ostarine as well as the probable side effects. The overview of this review can guide you in the purchase, use, sale, and consumption of ostarine.


Ostarine, popularly known as MK-2866 by many people and occasionally referred to as Enobosarm by few people is one out of the many SARMs we have around and apparently it is the most popular among all of them. Many may wonder what SARM is, SARM is an acronym for selective androgen receptor modifier which functions primarily as an active bind to receptors in order to target anabolic activities in muscles and bones. Ostarine happens to belong to this group of chemicals.

Traveling down the history lane, ostarine was invented alongside other SARMs in 1997, by GTx incorporated and as at then, it was specifically developed for the treatment of conditions such as muscle wasting and osteoporosis. In recent times, Mk-2866 is now known to be useful for more clinical conditions including helping to preserve muscle mass during the cutting phase.


One of the most amazing things about how ostarine works is the way it is very selective and specific in its actions. It specifically binds to the hydrogen receptors of the bones and muscles without affecting other tissues and organs of the body unlike the traditional steroids.

When used appropriately, you can expect ostarine to retain your muscle mass while simultaneously stimulating fat loss. This process will build muscle while also keeping it hard and strong. You can also expect ostarine to increase your strength, vascularity, endurance and overall body shape.


The purity and quality of the ostarine you use is very important, and it will determine if you will get your desired result. The use of adulterated or low quality product might be the reason most people are getting frustrated with the use ostarine. Getting your product from reputable and reliable source is very instrumental in getting a product that can be 100% guaranteed. We recommend selectSARMS as the #1 online retailer when you consider buying ostarine of high quality. They have a standard reputation of selling pure product at cost effective rates.


Just like every other chemical of clinical use, it is very important to use ostarine in appropriate dosage to avoid abuse that can lead to more complicated medical implications. Based on research, it was seen that ostarine works best when taken between the range of 10-30 mg per day and this dosage is largely dependent on if the user is cutting or bulking. Although for most people, it was found that that 10 mg per day is enough to give desired result but on average for wider range of people, ostarine is seen to work best at 20 mg per day. In most cases, there is no reason to take more in order to avoid extra suppression and other side effects.

It is very important for users to note that a cycle is usually measured between 8-12 weeks. Although taking a dosage of 10-30 mg for a cycle of 6 weeks works for some people but this might be too short and consequently ineffective in most people.

It will be of detrimental effect if higher dosage is taken in a bid to get instant result because for Ostarine to fully manifest itself and kick start its functions, it takes about a week or two and occasionally three or more in few people. Also, note that it is not advisable to use ostarine dosage with other steroids to avoid unforseen complicated issues.

It is very possible to experience muscle gains of about 6 to 12 Ibs on ostarine especially if you supplement it with strict diet.

It should however be noted that for perfect results, particularly those in bulking phase, it is advisable to take ostarine in a dosage of 20-30 mg per day for a cycle of at least 8 weeks. This routine on its own can help you reach your desired lean muscle mass without much concern about dietary changes. Nevertheless, it will benefit you to know that you have to avoid getting too low metabolism because it will make it much more difficult to burn fat particularly if you are in the cutting phase.

Nevertheless, it is important to know that most side effects of Ostarine comes from improper dosage. The manifestation of this side effects, if any include mild acne, mild headache, nausea, back pain, and lethargy which might be as a result of suppressed testosterone. But I however maintain that the use of ostarine is safer when taken with low dosage range. Likewise it is not yet established what the side effect will be when users take dosage for durations longer than the normal cycle.

Also users must pay keen attention and be sure of the quality and purity when purchasing ostarine.
