Ostarine MK 2866

Probably the most well-researched compound out there, Ostarine MK-2866 is considered a benchmark for SARMs’ standardization. The epitome of scientific research and the outcome of years of research, Ostarine has shocked the bodybuilding industry.

With minimal side effects and countless benefits including muscle growth, fat loss, endurance, strength, and treatment of various diseases such as degenerative bone disorders, this SARM has undoubtedly got it all.

A novel non-steroidal selective androgen receptor modulator (SARM), the drug has been investigated for the treatment of breast cancer, involuntary weight loss due to illness, and many other conditions besides its primary benefits of increasing athletic performance.

In addition, Ostarine demonstrates to be one of those potent anabolic steroids that have beneficial effects on muscle and bone with minimal effect on the prostate. Some studies have also indicated its effectiveness against muscle-wasting conditions and osteoporosis, with fewer side effects as compared to current treatments based on testosterone replacement.

Product Information

Ostarine is a SARM with obvious anabolic properties similar to those of androgenic steroids but with minimal detrimental effects. The drug was initially manufactured by GTx, Inc. for the treatment of conditions such as muscle wasting, osteoporosis, and breast cancer, and has proved, through clinical trials, for strength gains in skeletal muscles.

Additionally, the SARM has shown its potential for the treatment of degenerative disorders such as degenerative bone disorders and prostate cancer {R}.

Ostarine is a SARM that primarily targets ARs in muscle and bone tissue. It is believed to promote muscle growth, remove abnormal fat, and potentially enhance bone density while sparing other tissues from androgenic side effects.

How Does Ostarine Work?

SARMs, in general, have this tendency to selectively bind to ARs (androgen receptors). The human body typically has 47 nuclear receptors. While other compounds in the market are generic in their targeting of tissues and body receptors, Ostarine is very selective in its targeting of AR hence making it a good option for people looking for faster muscle’ gain.

Ostarine was created to help as a treatment for patients undergoing degenerative bone disorders. It was used for disorders such as arthritis and osteoporosis and also breast cancer {R}. It was designed to offer a safer alternative to anabolic androgen steroids and prohormones. It binds to androgen receptors found in the bone and muscle tissue.

Ostarine has taken the bodybuilding industry by storm and has proved its worth for its potential role in muscle growth, increased muscle mass, and gaining lean muscle. 

As a partial agonist, Ostarine is admired among bodybuilders for its ability to stimulate significant strength gains and improvements in muscle mass {R}. The best thing is that you can expect dramatic results within a short period of time. This is one product that you should buy if endurance, muscle mass, and strength gains are what you’re seeking.

Selective Androgen Receptor Modulators

Thus it is a selective androgen receptor modulator that doesn’t affect the other remaining nuclear receptors including steroid receptors, resulting in minimising unwanted side effects.

Due to its selective nature, this selective androgen receptor modulator not only causes zero potential side effects to other parts of the body but also helps reduce levels of high-density lipoproteins.

The suppression levels of Ostarine are minimal, unlike its competitors which typically makes this partial agonist increase estrogen levels which decreases water retention.

Ostarine MK-2866 Benefits

Ostarine, also known as MK-2866 or Enobosarm, is a selective androgen receptor modulator (SARM) that has gained attention for its potential benefits, particularly in the fitness and bodybuilding communities. Here are some potential benefits of Ostarine based on anecdotal reports and limited research:

1. Muscle Preservation:

Ostarine is often used during cutting phases or calorie deficits to help preserve lean muscle mass. It may reduce the risk of muscle loss that can occur when individuals are in a calorie deficit or undergoing intense training {R}.

2. Muscle Building:

Ostarine has been reported to promote muscle growth, similar to anabolic steroids, but with fewer side effects. Some users have experienced gains in muscle size and strength {R}.

3. Improved Bone Health:

Ostarine may have a positive impact on bone health and density. This could be particularly beneficial for individuals at risk of or suffering from conditions like osteoporosis {R}.

4. Decreased Body Fat:

Some users claim that Ostarine can help with fat loss and body recomposition. It has been shown that it may help increase metabolic rate and promote fat oxidation.

5. Improved Endurance:

Users have reported improved endurance and stamina when using Ostarine, which can be beneficial for athletes and fitness enthusiasts.

6. Joint Health:

Ostarine may have potential benefits for joint health by reducing inflammation and promoting joint lubrication. This can be especially helpful for athletes and individuals with joint issues {R}.

7. Minimal Androgenic Side Effects:

Ostarine is believed to have fewer androgenic side effects compared to traditional anabolic steroids. This means it may have a lower risk of causing side effects like hair loss, acne, and prostate enlargement.

8. Improved Recovery:

Some users have reported faster recovery times between workouts when using Ostarine, which can enable more frequent and intense training sessions.

9. Anabolic Effects:

Ostarine among other SARMs are compounds that are considered to have anabolic effects on muscle tissue, which means it may promote muscle growth and improved muscle protein synthesis, the effects highly desired among bodybuilders.

Ostarine – Side Effects:

It’s important to emphasize that the use of Ostarine and other SARMs is controversial, and there are potential risks and side effects associated with human consumption, including hormonal imbalances, liver toxicity, and cardiovascular issues.

Before considering Ostarine or any other performance-enhancing substance, it’s essential to consult with a healthcare professional who can provide guidance on its potential risks and benefits.

Dosage Ostarine

Amazingly, Ostarine has been clinically proven to significantly increase lean body mass in a dose-dependent manner without androgenic side effects in men or virilization in women and without statistically significant liver toxicity.

Gender, weight, body type, and medical history are major factors based on which dosage should be set by a professional healthcare provider. Generally, based on average users, it is recommended that Ostarine may be taken as 1 mg per 1 Kg of body weight which makes a dosage of 15-20 mg per day for a bodybuilder weighing around 200 kg. At this dose, people do not experience problems suppressing the organism’s natural testosterone production. Therefore, no recovery cycle or post-cycle therapy is needed.


Ostarine has undergone the most extensive clinical trials to date. In a recent study, Ostarine was shown to increase lean body mass and decrease fat mass, and modestly improve the homeostatic model assessment (HOMA), a measure of insulin sensitivity.

Is Ostarine Legal?

It is worth noting that the use of SARMs like Ostarine is not approved by the FDA for medical purposes, and their long-term safety and efficacy are still being studied.

Though not approved by the World Anti-Doping Agency yet, Ostarine has given a completely new dimension to SARMs’ popularity and may end up gaining not only unmatched popularity but also resolving legality issues.
