Ostarine, otherwise known as enobosarm or MK 2866, is one of the most popular SARMs on the market—and it isn’t hard to see why.
Just one cycle of this SARM has the potential to help users pack on some serious muscle mass, and completely transform their physiques.
Well unlike most of the snobby medical writers out there, I actually TOOK Ostarine myself, to see the kind of results it actually gives.
In fact, several websites even STOLE my Ostarine results pictures to sell their own FAKE scammy SARMS—and I’ll give you proof in this article.
So, if you want to learn more about this SARM, the best dosage, results to expect, and more, then here it is from someone who actually took it.
Before I get into my experience with Ostarine, and show you my results with it, I want to give a brief explanation of this compound first.
Ostarine belongs to a class of drugs known as SARMs, which were initially developed to treat cancer patients rapidly losing muscle mass.
While SARMs have been around since the 1940’s, they didn’t get much traction until GTx Pharmaceuticals came around in 1997.
This company, also known as GTx Incorporated, quickly began researching Ostarine after they discovered how powerfully anabolic it was [R].
In fact, this company fast tracked Ostarine (MK 2866) through FDA Phase II clinical trials, and we learned a lot from these research studies.
One thing we learned for sure about Ostarine, is that it’s a very powerful anabolic drug that has extremely potent, steroid-like effects.
All SARMs, from RAD 140 to Ligandrol to Ostarine, work in the exact same way—by binding to androgen receptors in your skeletal muscles.
After binding to these androgen receptors, SARMs then signal your body to build muscle at a rate faster than normal—similar to steroids.
One major difference between SARMs and steroids however, is that while steroids bind to all androgen receptors they come into contact with, SARMs were designed to only bind to skeletal muscle androgen receptors.
This means that when taking a SARM like Ostarine, users can get steroid-like effects, without many of the negative side effects that often come with using steroids, such as an enlarged prostate, for example. [R]
That isn’t to say that SARMs are 100% side effect free—there’s still a lot of research to be done, but preliminary research is very promising.
Before I get too deep into the clinical research, I want to show you the results I got from a cycle of Ostarine (MK 2866) and RAD 140.
Pictured above are the results from my third SARMs cycle. I gained 10 pounds of muscle and lost 4 pounds of fat in just 30 short days.
While I normally get my SARMs from Proven Peptides, I chose to try out the SARMs from Rat’s Army for this cycle—and they didn’t disappoint.
As you can see, the results I got from my Ostarine (MK 2866) stack were incredible—even in just 30 days, my body transformed entirely.
In fact, I had such incredible results, that several other SARMs vendors stole my review pictures to promote their own scammy, fake Ostarine.
Read that article if you want to see how a ton of SARMs companies are using results pictures they stole from me to promote their own products.
Anyways, within a few days of my first dose, I noticed a huge increase in strength, a higher level of energy, and much better pumps in the gym.
Ostarine works very quickly, because it has a half life of only 24 hours—so you get fast results, and it clears your system very rapidly, too.
Then, take one full dropper of each per day for 60 days straight. Follow it up with a post cycle therapy (PCT) which I cover later in this article.
Ostarine (MK 2866) is probably the most well-researched SARM out there, so thankfully there’s a lot of clinical studies to go off of.
The most obvious benefit of Ostarine is that it helps users build lean muscle mass, but there’s also many more health benefits beyond this.Here are a few Ostarine benefits:
Having been on an two Ostarine cycles (which I documented here), I can definitely confirm that all of these benefits live up to the hype.
The most obvious benefit of Ostarine is that it helps users pack on lean muscle mass, at a rate comparable to some steroids (like Anavar).
In fact, one clinical study found that even doses as small as 1 mg and 3 mg led to significantly more muscle gains than placebo. [R]
The study found that even this tiny Ostarine dosage led to an increase of 3 pounds of lean muscle mass in 4 months, WITHOUT working out.
When you consider that most recreational users take an Ostarine dosage that’s 10x higher than this, and they also workout while on cycle, it isn’t hard to see how this SARM can give incredible results.
In addition to helping users build lean muscle mass, Ostarine is also known for its ability to help users get shredded and melt off body fat.
While no studies have been done on the fat loss effects of Ostarine, there’s a ton of anecdotal evidence and user reports to confirm this.
Typically, you can expect to lose 10-15 pounds of fat from a 12 week cycle of Ostarine, although this will vary greatly depending on your dosage, diet, genetics, workout routine, and more.
Ostarine hasn’t been approved by the Food and Drug Administration, so there’s technically no recommended dosage for this compound yet.
That being said, most body builders and recreational users agree that taking between 25 mg and 50 mg of Ostarine is the sweet spot.
My first Ostarine cycle was at 25 mg per day, but some people who are less experienced (or more afraid) may choose to start off with less.
When using SARMs, it’s best to take your doses at the same time each day, to maintain an even level of the compound in your blood stream.
Some users take a SARMs stack, which is where you take multiple SARMs at once, to build lean muscle and lose body fat even faster.
The idea is that even though SARMs will all help you build muscle and lose fat, each SARM will have a slightly different effect on the body.
If you’re a beginner, you may want to start by using just one SARM at a time, but that said, let’s take a look at some common stacks.
Due to its versatility as a SARM, Ostarine is a great compound for both bulking and cutting stacks, as well as recomposition stacks.
|Bulking Stack||Cutting Stack|
|Ostarine (25 mg per day)||Ostarine (25 mg per day)|
|Ligandrol (20 mg per day)||Cardarine (10 mg per day)|
|Ibutamoren (25 mg per day)||Andarine (50 mg per day)|
In my opinion, Ostarine is one of the best SARMs out there, simply due to the fact that it can be used to accomplish so many different goals.
Ostarine is a great bulking SARM, because it promotes lean muscle growth, rapid fat loss, and an increased level of strength.
It’s also a great cutting SARM, because it can help speed up fat loss while dieting, AND prevent the muscle loss that often comes from cuts.
While I didn’t personally experience any side effects from my two Ostarine cycles, there are some potential side effects to be aware of.
Most of the Ostarine side effects can be mitigated with an AI and by also a proper post cycle therapy (PCT) which I discuss below.
Potential MK2866 side effects may include:
While these side effects may seem scary, most clinical research suggests that Ostarine is very well tolerated, with very minimal side effects. [R]
…and while I didn’t personally experience any major side effects on my Ostarine cycle, it’s still a good idea to educate yourself and be safe.
The biggest health concern most people have regarding SARMs is whether or not they’ll shut down testosterone production in the body.
When it comes to Ostarine, clinical research suggests that this SARM does NOT suppress the body’s natural testosterone production. [R]
That being said, the studies didn’t use dosages as high as the ones that body builders use, so doing a post cycle therapy (PCT) is a good idea.
I recommend you read my guide on doing a SARMs PCT, because doing the right PCT can help you keep and maintain your gains after cycle.
In conclusion, Ostarine is a very versatile SARM that can be used to build muscle, lose fat, increase strength, and transform your body.
Ostarine can be used to accelerate muscle growth while bulking, and it can also be used to keep muscle mass while on a cutting cycle.
Whatever you decide to use Ostarine for, I recommend you get it from a good source—both Rats Army and Proven Peptides are great.
Every product that they sell is 3rd party verified for purity, so you know you’re getting 100% pure muscle building, fat shredding SARMs.

Anyways, I hope you guys enjoyed the article—let me know if you have any questions down below, and as always, I’ll see you next time!
Ostarine is legal to be bought and sold as a product, but it is not legal for human consumption. Currently, all SARMs are legal to sell and purchase in every country around the world, except for Australia.
Thankfully, Ostarine (MK 2866) is a relatively safe compound when compared to other SARMs. Some users may experience mild testosterone suppression and a decrease in both good and bad cholesterol, but research suggests that MK 2866 is fairly well tolerated.
Ostarine (MK 2866) has a half life of roughly 24 hours, meaning that the drug begins working on the body shortly after ingestion. Most of the compound will be cleared from your system within just 3 days.
