What is Ostarine (MK 2866)?

Ostarine is a selective androgen receptor modulator that is designed to boost your muscle growth. This product also prevents muscle wasting and helps you to increase your overall muscle mass, and strength. However, the working mechanism of Ostarine is quite different from the common anabolic steroids. Unlike these steroids, Ostarine doesn’t affect your system with dangerous side effects. In the next few sections, we will assess the benefits, basic principles and working mechanism of Ostarine in detail.

This product will directly impact the anabolic activity of your system, without loading your body with plenty of hormones. Like steroids, ostarine too will target your androgen receptor, but contrary to their working mechanism, it’ll not convert your receptors to estrogen. With Ostarine, you can easily avoid the side effects that come with steroids.

How Does MK2866 Work?

MK-2866 is a special kind of SARM that has been designed for helping patients deal with the terrible effects of muscle wasting and bone wasting ailments. Since it doesn’t impact any other muscle tissue than the skeletal ones, it is one of the most valuable treatment solutions among patients.

Medical Uses and Advantages

You find plenty of drugs that promise you significant muscle gain. However, all of them aren’t really effective in improving your lean muscle mass. If you’re a fitness enthusiast, you would want proper, and consistent muscle gain. And this is exactly where Ostarine can help you. Unlike the commonly available supplements, ostarine promises you a healthy, holistic muscle gain. You won’t have any watery gains with it. On the contrary, you will enjoy proper, lean muscle gains.

Unlike the widely available chemical supplements, MK 2866’s anabolic effects directly target your muscle tissues. This, in turn, helps it to deal with the issues of muscle wasting. Additionally, it also promotes your muscle build, which is particularly relevant for budding athletes.

Yet another significant benefit of ostarine is the fact that it assists you in lowering the risks associated with degeneration. This is all the more relevant when you’re just recovering from a specific surgery or from some similar other condition.

According to the makers, MK 2866 has passed through eight scientific trials and three efficiency tests. Each of these tests has proved that MK 2866 is a much better option for building lean muscle mass when compared to placebo.

Additionally, MK 2866 has also been extremely useful in enhancing your overall muscle strength. Since the side effects too are relatively minimal, several people vouch for this option.

Specific Advantages for Athletes

Ostarine is particularly useful for athletes because it helps them in gaining leaning muscle mass. Although it doesn’t offer similar muscle gain as steroids, athletes can expect the gain in their overall muscle mass. Steroids have a bad reputation for leading to water retention, which is equally frustrating as gaining excess fat. However, such is not the case with ostarine. Once you take this product, you can enjoy faster, easier and a tad more hassle-free muscle recovery after your workouts. Additionally, the results you’ll gain will be relatively easier to maintain. The supplement is extremely effective, and both males and females can benefit from it.

In addition to helping athletes build lean muscles, ostarine also helps in burning fat. In order to lose weight, you need to burn more calories than you consume.

Any athlete will confirm that gaining muscle mass isn’t an easy job, and it takes up a lot of your time. Additionally, it also turns out to be extremely tedious. And this is exactly where Ostarine can help you. This product is rich in muscle preservation properties that help you to prevent atrophy.

Your bone health is likely to decrease with age, and this is yet another aspect where Ostarine can help you with. As we already know, ostarine increases muscle mass. Interestingly, higher muscle mass leads to enhanced bone health. Additionally, it also cuts down the risks of bone fractures or speed recovery. Your muscles support your skeletal system and ostarine helps you in boosting it.

  • Better Heart Health

It has been observed that ostarine also improves your heart health. So if you’re someone who suffers from heart issues once in a while, this is one product that’ll definitely work in your favor.

Side Effects

Tips on Dosage

Ostarine is usually taken orally. You can take it either in the form of pills or a solution. In case you’re taking it as pills, you’ll need at least one to two pills every day. If, however, you are looking forward to some drastic increase in the muscle mass, try opting for up to three pills every day. It will take you around four weeks of consistent use for proper, visible results.

MK-2866 is usually taken in cycles that normally range from six to eight weeks. Once you complete a single cycle, avoid taking any form of SARM for at least four weeks. This will help you with the recovery process. Although Ostarine doesn’t come with any major side effects, it is always better to stick with the prescribed dose without overdoing it. In case you’re still unsure, here are a couple of things you should ensure-

    • Avoid taking more than 3 pills even if you look forward to drastic improvement.

      • Do not take any SARM product for three to four weeks if you want a quicker recovery.

  • Always stick to your suggested dose for quick results.

For the Bulker

This sarm has really been seen to prove its self here. Patients right now are suggesting a dosage of 25mg over a 4-6 week period. However, I have heard of patients going as high as 36mg for 8-week cycles. When doing this please look into post cycle to come down after

For the one looking into a little body recomposition

Mk-2866 should still be a winning choice as well. Using calories to build up muscle also will aid in helping reduce fat and improving strength in doses of  12.5-25 for 4-8 week cycles (diet will also help here keep at least 35 percent of your protein sources lean for peaked results)

For the Shredder looking to just lean out

With a reduced calorie diet patients have been noticed using about 12.5-15mg for 4-6 week cycles

MK2866 stacks great with LGD-4033 and Testolone.
