Ostarine (MK2866) is a powerful and effective Selective Androgen Receptor Modulator (SARM) which has the ability to improve strength, endurance, and lean muscle mass. MK2866 is excellent for preserving muscle when in a fat loss or cutting cycle. It will stop muscle wastage, heal connective tissue, build lean muscle and increase bone density.

SARMs can help fitness enthusiasts to enhance their overall performance without resulting in the consequences of usual steroids. SARMs are supposed to join with androgen receptors at the primary cellular level.

Greater strength

Reduced body fat

Increased muscle mass

Reduced recovery time

Increased lean mass gains

SARMs retain the muscle mass in the body and ensure that the hardness of the muscle remains for a longer period. However, the anabolic compounds improve muscular hardness when it is combined with regular exercises and a healthy diet. Also, it is advised that no steroids must be taken in the process to avoid any future complications.

Increased endurance

Even though SARMs are used for muscle growth and formation, the benefits of the compounds are unparallel. The effects of SARMs are also visible on effective cardio workouts. Since both muscle training and cardio workout requires increased stamina and endurance, SARMs activates the body receptors and increase the endurance of individuals for better performance and lifestyle. There are various reports and clinical trials that back the effectiveness of SARMs in increasing stamina and endurance.

Joint healing abilities

Joint injuries are inevitable for athletes. The major causes of joint healing abilities revolve around bone degradation and low muscle strength. SARMs work on the causes and ensure that bone degradation does not happen in the workout process. Even if joint injuries occur, the anabolic compounds present in different SARMs fasten the joint healing and recovery process.

MK2866 (Ostarine) is a powerful and effective SARM which has the ability to improve strength, endurance, and lean muscle mass while healing several health conditions. MK2866 has been used to heal osteoporosis and even prevent injuries. Ostarine may also be beneficial for people with heart disease, who often suffer from muscle wasting and weight loss. This SARM’s insane versatility is also well known and enjoyed by many lifters and by a variety of athletes.

Since it mimics testosterone in the muscles and bones, it has the potential to prevent bone diseases. It’s multipurpose enough for use in the cutting and bulking phases and it has no recorded side effects. Ostarine can help stimulate fat oxidation in humans. Users who are in a caloric deficit will experience much better muscle retention. 

MK2866 almost exclusively uses its anabolic effects on muscle tissue, therefore it is been shown to be a great substitute for testosterone because it has no negative side effects physically and was great ability  to not  only gain lean muscle mass but also has the ability to minimize muscle atrophy and other muscle wasting disorders. MK2866 is the most anabolic of all SARMs therefore it produces increases in lean muscle mass, strength increases, increases in healing properties, and improves endurance.

For the most part, MK2866 is taken in doses between 10 mg to 25 mg, although some users and bodybuilders have taken over 50 mg per day. The standard beginner’s MK2866 dosage for bodybuilding is 10-15 mg per day — most users find that this is enough to get great results.

Ostarine has a remarkable half-life of 24 hours. This implies that a single dose per day is sufficient to exhibit incredible benefits. If you take more Ostarine than 25 mg per day, you will likely experience faster muscle gain and faster fat loss, however — be careful. Although MK2866 is well studied, for the most part, there is still a lot of uncertainty when it comes to the longer term side effects.

The optimum period of use is 4-12 weeks. If used for this recommended time span, there is no need for PCT (post cycle therapy). In case if the drug is abused for a longer duration, PCT is advised.

The opinions are mixed when it comes to Post Cycle Therapy (PCT) after using Ostarine. Some don’t feel the need for it after Ostarine, especially with lower doses (approximately 10 mg per day). Others consider both anti-estrogens and aromatase inhibitors a must after Ostarine cycles. We would still advise a PCT after Ostarine as it still could suppress your natural testasterone. The only way to know for sure if testosterone has been suppressed is with blood work (recommended).

Ostarine can also be stacked with other SARMs to drastically increase the effects. In fact, on a SARMs stack, users can expect to gain far more muscle mass, lose far more fat, and transform their overall body.

Depending on your goals, you can personalize the Ostarine stack or cycle you are going to follow. If you want to lose weight, taking it with Cardarine (GW501516), Stenabolic (SR9009) or Andarine (S4) would be a good idea. If you want to bulk up we suggest that you use LGD4033 or RAD140.
