OSTARINE VS Selective Androgen Receptor Modulator (SAMRs)

January 10, 2023Author:MuseChemTAG:Bioactive Chemicals

What is Ostarine

OSTARINE, also known as MK-2866, GTx-024 and Enobosarm, is a selective androgen receptor modulator (SARM). MK-2866 is one of the most widely used SARMs in the world and one of the first SARMs to pass human clinical trials. MK-2866 is primarily used to combat muscular dystrophy and osteoporosis. Many speculate that MK 2866 may be used in hormone replacement therapy programs, as well as for the treatment of sarcopenia, extreme wasting and muscle wasting. This is a very beneficial product for those suffering from muscular dystrophy disorders as SARM has been shown to have no effect on non-skeletal muscles.

As a SARM, MK 2866 binds directly to the androgen receptor. Although anabolic steroids also bind to androgen receptors, SARM cannot be converted to DHT or estrogen, and the sole purpose of MK 2866 is to directly participate in the body’s anabolism. The SARM can be used for muscle growth or muscle preservation (diet dependent).

MK 2866 takes full advantage of its anabolic effects on muscle tissue, so it can not only treat muscle wasting diseases, but also provide incredible benefits to athletes who want to build muscle. It is also a less degenerative agent during recovery from serious surgery or similar situations.

Ostarine’s Application Advantages

1)MK 2866 muscle building

Ostarine users have confirmed that MK 2866 can help improve muscle mass and strength levels. Ostarine would be a good choice if you are planning to build muscle, it is a substance with muscle synthesis ability and can enhance your muscle strength and reduce fatigue, more importantly, it can promote protein synthesis and help increase net muscle mass, unlike other steroids, it does not cause fat gain or water retention. Whether you want to lose body fat or increase muscle mass, it can provide you with amazing results.

2)MK 2866 can be used for weight loss

Ostarine is a very useful tool for weight loss. It ensures that your calorie intake exceeds your intake. Those who use Ostarine for fat loss can appreciate that, especially if you are in a severe energy deficit, using it together can enhance the fat loss effect, because the calorie deficit produces a slower metabolic rate and a decrease in IGF and testosterone concentration, a state in which the body tends to enter a catabolic state. When you are in a deficit state, Ostarine can prevent your muscles from being catabolized to provide your body with the energy it needs, so that you don’t have to worry about losing too much muscle during the fat loss period. Therefore, adding Ostarine to your diet can be of great help, and many users have confirmed that they word a significant reduction in body fat after using this compound.

3)MK 2866 for shaping

One more thing, Ostarine does not cause gynecomastia in men. Therefore, there is no need to worry about developing female breasts. In addition, Ostarine shortens the recovery time so you can work out more frequently.

MK 2866 is a more side effect friendly drug

MK 2866 has limited side effects and it is a relatively side effect friendly drug. The SARM does not have many of the adverse effects associated with anabolic steroids, however some people do experience some side effects and it can cause some mild ones such as a slight increase in your estrogen levels. This slight increase can sometimes be beneficial to you as it helps to heal injured joints. It is recommended that you avoid taking any anti-hormonal medication during your cycle as it can lead to hormonal imbalances.

MK 2866 does not have androgenic side effects despite its direct effect on androgen receptors. MK 2866 cannot be converted into dihydrotestosterone DHT, therefore, it will not cause any harm to your sexual organs and likewise will not cause problems such as acne and hair loss.

MK 2866 causes fluctuations in lipid levels, and both HDL and LDL levels may be reduced, but study data show that fluctuations in lipid levels are so insignificant as to be almost negligible.

It is often said that SARM does not suppress its own testosterone production, however a mild suppression is possible but never a complete suppression like that of steroids. When using MK 2866, it is possible to use it with some testosterone promoting products, and mild PCT recovery is possible in high dose long cycle situations.

Despite the oral route of administration, MK 2866 is not hepatotoxic and does not affect liver or heart health. MK 2866 does not belong to the C17-alpha alkylated (C17-aa) class of drugs, and it does not reflect the MI metabolites associated with SARM S4, which gives some hepatic activity to this specific SARM.


Ostarine is not only expected to improve the quality of life of patients as a therapeutic option, but also has the potential to become an adjunctive treatment. With the current popularity of Ostarine in the clinical setting and in life, it has a more promising application.
