Ostarine For Beginners: The Science-Based Guide to MK-2866 (Results, Studies, & More)

Ostarine, otherwise known as MK 2866 or Enobosarm, is one of the most popular SARMs on the market, which helps users rapidly build muscle.

In fact, Ostarine has exploded in popularity in the past several years, with dozens of athletes and weight lifters testing positive for MK 2866.

What does the research say, however? Is MK-2866 safe for human use, and does it actually lead to incredible performance enhancement?

In this article, we’ll explore the benefits of Ostarine, the best dosages, clinical studies, how much muscle users can gain, and much more.

What is Ostarine?

Ostarine, sometimes called MK-2866 or Enobosarm, is one of the most popular selective androgen receptor modulators, or SARMs for short, used to rapidly build muscle and lose fat.

MK 2866 has been around for decades, but was licensed to GTx Incorporated in 1997, and has since been undergoing clinical research. [R]

While the details of studies vary, most research agrees that Ostarine is a potent muscle-building compound with minimal side effects.

This is why SARMs are often used by bodybuilders and athletes to enhance their performance, build lean body mass, and attain supra-physiological feats of strength.

MK-2866 is, essentially, one of the best legal steroids on the market.

Ostarine History

Ostarine was initially developed by GTx, Inc. for the treatment of osteoporosis and muscle wasting.

In 2011, a double-blind placebo-controlled trial showed that Ostarine increases total lean body mass and physical function in healthy men as well as postmenopausal women. That too without the side effects caused by anabolic steroids. [R]

However, in two subsequent phase III clinical trials in 2013, Ostarine failed to treat wasting in lung cancer patients. [R]

Three years later, another phase II trial was conducted to treat stress urinary incontinence in females, but Ostarine once again failed to achieve the primary endpoint. [R]

Yet, this hasn’t stopped bodybuilders from using Ostarine to build muscle mass, increase lean body mass and reduce body fat levels.

Overview of Pros & Cons

Before we delve deep into the clinical studies surrounding Ostarine and other SARMs, let’s take a brief look at the pros and cons of this SARM.

The benefits of MK-2866 include:

• Increased Muscle Mass
• Improved Bone Density
• Very Fast Results
• Backed By Ample Data
• Faster Recovery Time
• Rapid Fat Loss

The potential drawbacks include:

• Can Have Negative Side Effects
• Potentially Unknown Effects on the Body
• Not Approved For Human Use (Yet)
• More Data on Long-Term Side Effects is Required

While MK-2866 has generally been shown to be safe in healthy individuals, more data is needed to determine if SARMs as a whole are safe long-term.

This being said, Ostarine presents enormous promise to be used as a way to treat cachexia (muscle atrophy) in cancer patients, as well as other conditions, and is currently undergoing FDA trials.

Is It Legal?

Ostarine, as well as other SARMs, are strictly prohibited by the World Anti-Doping Agency (WADA) for athletic use. So, if you’re an athlete and test positive for SARMs, you could be disqualified from competition. [R]

The USADA, or the United States Anti Doping Agency, has also banned SARMs from competition, so if you’re an athlete and get drug tested regularly, it’s highly recommended that you avoid SARMs.

That being said, SARMs are completely legal to purchase.

In other words, it’s completely legal to buy SARMs for Sale Online—we advise you to go through a reputable vendor however, like the ones in that link.

Many individuals order Ostarine for personal use, as it’s legal to sell as a “research chemical,” and end up taking it for bodybuilding.

How to Get MK-2866

The FDA and USADA have warned in the past about vendors who sell fake SARMs, which is why it’s so important to get them from a good source.

If you’re just skimming and want to get 99% pure Ostarine (MK-2866), tested by a 3rd party laboratory, then we recommend you get it through Pure Rawz.

Every batch of their SARMs is 3rd party verified by an independent laboratory, so you know for a fact that what you’re getting is real.

How Does Ostarine Work?

NOTE: If you’re just looking to buy 99.9% pure, high quality Ostarine online, we recommend Pure Rawz – use the code “MD15” for 15% off your entire order.

Similar to all SARMs, MK-2866 works by binding to androgen receptors in your body, signaling muscles to rapidly start growing and repairing.

In other words, Ostarine begins working shortly after ingestion, and signals your body to pack on slabs of muscle in very short periods of time.

What SARMs unique is that they’re selective in nature. They only target bone and muscle tissue, sparing reproductive organs from harsh sides.

In other words, they gives steroid-like effects, without aromatization. [R]

While MK-2866 does not aromatize in the body, it must still be noted that this doesn’t necessarily make it safer than steroids—in fact, many have pointed out that aromatization is necessary for overall health.

MK-2866 vs. Steroids

While SARMs may have unknown long-term effects on the body, we do know that they can give steroid-like effects in the short run.

Many users report gaining over 10 or 15 pounds of muscle in a very short period of time, while also burning off fat and increasing their strength.

It is for this reason that people love using Ostarine for bodybuilding—not only is it a powerful anabolic compound, but it’s also legal to buy and sell.

Benefits of Ostarine

Ostarine, otherwise known as MK2866, offers a plethora of benefits for bodybuilders, which is why it’s such a popular SARM on the market.

The benefits of Ostarine include:

• Rapid Muscle Growth
• Enhanced Athleticism
• Accelerated Fat Loss
• Increased Bone Density
• …and more

Ostarine has been proven many times through clinical studies to have a very beneficial effect on muscle growth and overall body mass index.

Rapid Muscle Growth

Perhaps the most well-known benefit of Ostarine is the fact that it causes rapid muscle growth in users who take it. In fact, this is one of the primary reasons that bodybuilders and athletes take Ostarine.

One study, for example, conducted on 120 elderly people, found that even a dosage as small as 3mg per day led to statistically significant improvements in muscle mass. [R]

This SARM in particular is known for having a strong effect on androgen receptors and is comparable to a low dosage cycle of steroids.

Enhanced Athleticism

It’s no secret that using MK-2866 for bodybuilding is one of the main reasons why people choose to take Ostarine in the first place.

Users often report gaining over 10 pounds of muscle from an 8-12 week cycle of Ostarine, and often even more if they take higher doses.

Accelerated Fat Loss

Due to the anabolic nature of Ostarine, consuming MK-2866 also makes it far easier to lose fat, due to increase in your metabolic rate.

In other words, as the Ostarine works in your body to pack on more muscle, it will burn calories much faster to do so, meaning you can burn fat and build muscle at the same time, with relative ease.

In our experience, MK2866 is one of the best SARMs on the market right now for cutting fat and for staying lean on a bulking cycle.

Increased Bone Density

Not only does Ostarine increase lean muscle mass in users, but it also improves bone density, particularly in elderly individuals.

In fact, Ostarine is currently being researched in clinical studies as a potential way to prevent bone fractures in those with bone wasting diseases.

How to Take Ostarine

For the most part, MK-2866 is taken in dosages between 10 mg to 25 mg, although some users and bodybuilders have taken over 50 mg per day.

The standard beginner’s MK-2866 dosage for bodybuilding is 10-15 mg per day—most users find that this is enough to get great results.

If you take more Ostarine than 25 mg per day, you will likely experience faster muscle gain and faster fat loss, however—but be careful.

Although MK-2866 is well studied, for the most part, there is still a lot of uncertainty when it comes to the longer term side effects.

It’s also important to note that most of the studies conducted using Ostarine used dosages far less than the dosage that bodybuilders take. In fact, studies have shown that simply taking 3 mg of Ostarine per day will yield results.

Dosage For Bodybuilding

Most bodybuilders find that taking 15 mg of Ostarine is sufficient to yield rapid muscle gains and accelerated fat loss, however some take more.

If you’re a beginner, it’s recommended that you start by taking 15mg per day, at the same time each day, for an 8-week cycle to start.

More experienced users can take up to 25 mg per day, although there isn’t much research to support whether or not this is safe in the long-term.

Cycle Guidelines

For the most part, SARMs are taken in cycles of either 8 or 12 weeks, depending on the experience of the user and the desired results. While on cycle, be sure to increase your protein consumption and macros by a lot.

For Ostarine (MK-2866), it is recommended that you start by taking 15 mg per day for 8 weeks, and then follow this up with a post cycle therapy.

A standard Ostarine cycle might look something like this:

• Weeks 1-8: Take 15 mg Ostarine per Day
• Weeks 9-12: Begin Post Cycle Therapy
• Weeks 12-16: Take A Break From SARMs

It’s generally recommended that users have at least 4 weeks in-between SARMs cycles, and ideally even longer than this. The more time you give your body to recover and reach equilibrium, the better.

Stacking Guidelines

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.

A good bulking stack would be:

• Ostarine (MK2866) – 15 mg
• Ligandrol (LGD4033) – 15 mg
• Ibutamoren (MK677) – 25 mg

Taken once per day, for 8-12 weeks, followed up by a PCT, this bulking cycle would yield incredible gains in muscle mass and overall strength.

A good cutting stack would be:

• Ostarine (MK2866) – 15 mg
• Cardarine (GW501516) – 10 mg
• Andarine (S4) – 50 mg

Taken daily for 8-12 weeks, again, followed with a post cycle therapy (PCT), this cutting stack would allow users to lose fat at a supraphysiological rate.

A good recomp stack would be:

• Ostarine (MK2866) – 10 mg
• Ligandrol (LGD4033) – 10 mg
• Testolone (RAD 140) – 10mg

Taken once per day, for 10 weeks, this stack will increase muscle mass and shed excess fat simultaneously, something that is difficult to achieve with bodybuilding alone.

Ostarine Side Effects & Safety

While most individuals who use Ostarine (MK2866) don’t experience many side effects, there are some rare cases where they may occur.

The most common Ostarine side effects include [R]:

• Decreased HDL Levels
• Back Acne
• Joint Pain
• Increased Hunger
• …and more

Some individuals may experience accelerated hair loss while taking Ostarine, however simply using RU 58841 can counteract this effect.

Again, most individuals don’t experience many side effects while taking MK-2866 for bodybuilding, however more long-term research is needed.

Post Cycle Therapy

As with all SARMs, taking a post cycle therapy is highly recommended. The point of a post cycle therapy (PCT) is to restore natural testosterone levels.

There are two ways you can do this. The first is by taking a natural, over-the-counter testosterone booster as your post cycle therapy.

This will work well for most individuals, but for users taking a higher dosage of Ostarine, something like Nolvadex may work better.

In fact, we recommend you read our SARMs PCT guide for more info on how to run a proper post cycle therapy so for hormonal health.

Ostarine Summary

All in all, MK 2866 is a powerful SARM which has been clinically proven to build muscle in users, even in dosages as low as 3mg per day.

If you do decide to use Ostarine for bodybuilding, be sure to get it from a good source that’s 99% pure and 3rd party verified, like Pure Rawz. Just use the code “MD15” and you’ll get a whopping 15% off.

Always follow up any SARMs cycle with a post cycle therapy, and most importantly, monitor your blood work to assure safety.
