Ostarine – SARM #1

What is ostarine?

Ostarine ((2 S)-3-(4-cyanophenoxy)- N -[4-cyano-3-(trifluoromethyl)phenyl]-2-hydroxy-2-methylpropanamide), also known as MK-2866, GTX 024 and enobosarm, is a selective androgen receptor modulator.

It is a substance being helpful during osteoporosis and chronic diseases destroying muscles.

SARM MK-2866 Ostarine

What is its action?

MK-2866 binds to the ARs demonstrating an anabolic effect. Ostarine does not convert to estrogen and DHT, because it has not a steroid structure. Thanks to that, enzymes that convert to the aforementioned hormones on a reductase and aromatase, are unable to join. Additionally, in contrast to testosterone and other anabolic steroids, SARM not induce effects on the growth of prostate cancer and other genital organs.

Nevertheless, we often hear about the increased level of estrogen during ostarine supplementation. This is due to the stimulation of the androgen receptors. In the organism, in natural conditions, there is also the phenomenon of aromatase, stimulating receptors results in just such changes. Estrogen at the appropriate level is beneficial for our joints. This happens due to anti-inflammatory action, and collagen synthesis mechanism stimulation, whose product is a component of our tendons, skin, and articular cartilages.

Action confirmed in the scientific study on efficacy of MK-2866 administered to people over the age of 60, and women after menopause. It is worth noting that these waere people were not exercising in the gym for sure, so their incentives for growth were not too big!


How to dose?

Ostarine has a half-life of approximately 24 hours, so we take it orally once a day – thanks to that it offers a very convenient form of supplementation.

15-20 mg is the basis to achieve gains in lean body mass.

20-30 mg, if we want to achieve a spectacular performance of muscle mass and strength.

10 mg, if we want to improve the condition of the joints, and the overall efficiency of production of collagen.

Individual proportions of a dosage we use in more complex cycles, for example: prohormones + SARM or SARM + PCT. You should consult doses with specialists.

Ostarine is also very beneficial in the world of endurance sports such as cycling and running, resulting in a huge improvement in muscle strength.


1. Ostarine has an anabolic effect just at a dose of 3 mg

2. Compared to steroids it does not convert to estrogen

3. It does not block the HPTA – we do not need PCT

4. It increases the synthesis of collagen – the regeneration of the skin and joints

5. The half-life and oral form makes it easy to use
