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.
Mechanism of Action
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 such as Ostarine 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 such as Ostarine 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 Ostarine is 100% side effect free—there’s still a lot of research to be done, but preliminary research is very promising.
My Ostarine Review
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 Ostarine and RAD 140 from Rat’s Army for this cycle—and they didn’t disappoint.
My Ostarine Results
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.
Overview of my Cycle
Overall, my Ostarine cycle was great. I put on a ton of muscle, shredded tons of fat, and it happened rapidly, too. I recommend Ostarine for ANYONE who wants to do a body recomposition.
Ostarine Dosage: 25 mg Per Day
RAD 140 Dosage: 20 mg per day
Length of Cycle: 30 Days (4 Weeks)
PCT Protocol: Natural Test Booster
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.
If you want to get results like mine, try grabbing two vials each of the Ostarine (MK 2866) and Testolone (RAD 140) from Rat’s Army.
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’s A Few Ostarine Benefits:
Build Muscle Mass
Enhanced Protein Synthesis
Decrease Body Fat
Gain Tons of Strength
Improve Bone Density
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.
Build Muscle Mass
The most obvious benefit of Ostarine is that it helps users gain 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.
Decrease Body Fat
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.
How to Take Ostarine
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.
Recommended Dosage Overview
Since Ostarine isn’t approved by the FDA, there’s technically no medically researched and recommended dosage (like I said). With that in mind, however, here is what most body builders recommend.
Beginner Dosage: 15 mg per day
Intermediate Dosage: 25 mg per day
Advanced Dosage: 50 mg per day
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 such as Ostarine, 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.
How to Stack It
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.
Sample Stacks & Cycles
Due to its versatility as a SARM, Ostarine is a great compound for both bulking and cutting stacks, as well as recomposition stacks.
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)
Sample Ostarine (MK-2866) Stacks
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.
Ostarine Safety Guidelines
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 Side Effects May Include:
Oily Skin & Acne
Mild Liver Toxicity
High Blood Pressure
Lowered HDL Cholesterol
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.
Post Cycle Therapy
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—Rat’s Army is currently my favorite, so I recommend the Ostarine for sale on their website.
Every product that they sell is 3rd party verified for purity, so you know you’re getting 100% pure muscle building, fat shredding SARMs.
Also if you do want to get some Ostarine, use code “MD20” to save 20% with Rat’s Army—you’ll save money on any SARMS you buy (not just Ostarine)!
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!
