MK-2866 Ostarine Review: Benefits, Best Cycle & Where To Buy
Ostarine, also known as MK-2866, and less commonly as Enobosarm, or Ostamuscle, it’s probably the most popular SARM available. In this Ostarine review, I’m going to talk about the best place to buy Ostarine, as well as all you need to know about using it.
I’ll tell you about the correct Ostarine dosage, how to use it when to use it, plus the effects you can expect to benefit from. And believe me, it’s possible to strip fat, and build muscle with this stuff.
In addition, I’ll tell you about the two best places in the USA today where you can buy pure SARMs, including amazing quality, certified pure, Ostarine.
What Is Ostarine Good For?
Ostarine is one of the groups of chemicals, as yet unregulated, that had been designed to help with various conditions, including muscle wasting conditions. That makes them fantastic for not only helping to maintain muscle but build it rapidly.
SARMs have been designed to be a side-effect free as possible. However, I’ll talk more about side-effects later, as there is a lot of misleading information out there about them.
Ostarine is a brilliant compound for building muscle. But it’s not as good at that as some of the more powerful SARMs out there. That’s why it’s seen as a beginner SARM, because it produces results, but is milder.
But it’s also really good at cutting fat, which is why so many people use it for the cutting phase specifically.
Others use it while they are recomping. Eating at maintenance, or even a slight deficit, lifting weights several times a week, doing cardio, and slowly generating more muscle, while losing fat.
So for me, MK-2866 Ostarine is a brilliant beginners SARM. But more than that, it’s good for experienced people who don’t want to go too fast, and also it’s great for stacking because it can be stacked alongside a more powerful muscle builder, to help with cutting at the same time.
But don’t make the mistake that many do, of thinking that Ostarine is only good for cutting.
How Ostarine MK 2866 Works
All of that sounds amazing, and a lot of people are skeptical about the benefits of SARMs being real.
So how exactly do SARMs like Ostarine work, and is there any scientific evidence that they generate the incredible results you will see online?
SARMs work by binding to androgen receptors in our body. These receptors are mostly found in our muscles, and other similar tissues and they communicate with the body to help it regulate itself.
The full name of SARMs, Selective Androgen Receptor Modulators, should give you a huge clue as to how they work.
But in essence, they selectively target the androgen receptors and modulate the natural messages, increasing them, which tells the muscle tissue to grow faster, faster than natural.
The side-effects of SARMs are allegedly low because they selectively target specific androgen receptors relating to muscle and fat. This is in contrast to anabolic steroids, which have a wide range of negative effects around the body, especially in organs like the liver.
Now look, I’m going, to be honest with you here, in a way a lot of people talking about using SARMs like Ostarine won’t be.
There is no ideal dose of any SARM. No guidelines, no safe level. The reason for this is simply that nobody knows. Because they are unregulated, and clinical trials to regulate them for human consumption have never been done, nobody actually knows the full effects, side-effects, consequences or benefits of using them.
So the dose is subjective. My advice to you is simple: use the lowest possible dose you can.
With me, I start with a low dose. When I was first starting out, I did start with Ostarine, because it was the mildest SARM.
A high dose of almost any SARM is anything over 30 mg per day. I’ve seen some crazy folk out there taking double, treble that, but I really think that’s pretty insane.
I started on just 10mg per day. I did that for a cycle of eight weeks, and I had a four-week break, and then I had another eight-week cycle, where I went up to 20mg per day. I did start to see effects, I was losing fat, and building muscle.
I then stacked it with RAD-140 Testolone, and that dramatically increased things happening. But if I’d continued with Ostarine on its own, I would offer you the advice of sticking to 10-20mg per day as a beginner, or for cutting, and no more than 30 mg a day if you are using on its own to build bulk, while cut at the same time.
But please be aware, when you’re trying to work out the right Ostarine dose for you through trial and error, that if you are stacking it with other SARMs, that you are putting several things into your body that all do roughly the same thing but at different strengths.
So if you are going to stack Ostarine, then your dosage should be totaled with the others. Which means, if you are taking 3 SARMs, each 15mg, that’s actually a total dose of 45mg, which is heading into the territory at which you should be very careful.
However, as I say, it does appear to be a mild SARM. So if you’re going to use on its own, a slightly higher dose than something like YK-11 will be necessary, and tolerable.
Let’s Talk About The Right Ostarine Cycle
The question around what the best Ostarine cycle is gets asked a lot. As you may have realized with me just talking about the correct Ostarine dosage being impossible to dictate, it’s about personal trial and error, so it’s the same with choosing the right cycle.
However, there are some pretty specific cycles that most people seem to stick to unless they are being extreme.
For me, the best Ostarine cycle looks like this:
- 10-20mg per day for cutting, 20-30mg a day for building
- Maintain cycle daily for eight weeks
- Break of four weeks before a new cycle
- Use a PCT if you get symptoms of testosterone depression
That’s it really, it’s pretty straightforward. It’s just about changing the dose slightly. So if during the cycle you not seeing many results, especially second and subsequent cycles, then put on an extra 5 mg per day, and see what difference that makes. In essence, it’s all about finding the “sweet spot” for you.
I guess what you could do, if you don’t want to use a more powerful SARM than Ostarine, but you want better results, is to think about the following:
- Consider a higher dose
- Consider extending the cycle, although I wouldn’t go more than 10 weeks
- Consider lowering the break, but don’t lengthen the cycle of the same time
Results From Using Ostarine
Look you’ll read online that every SARM is the “most anabolic”, implying it’s really powerful but much safer than anabolic steroids, or prohormones.
While Ostarine is undoubtedly one of the safest SARMs, it’s not anywhere near anabolic in its effects.
But you will see definite results, usually within the first cycle of eight weeks. As long as you back it up with a good routine of weights, cardio, and the correct diet.
Ostarine takes a little while to kick in, usually a couple of weeks. If you keep going through the eight-week cycle, then by the end of it you should see a few pounds of lean muscle increase.
You’ll also feel stronger, significantly stronger by the end of the first cycle.
You’ll also lose fat. Obviously, if you are cutting, you will lose more, but because it’s a SARM unless you go extreme, then you will maintain muscle, or even slightly gain it still.
Coping With Ostarine Side Effects
The great news about Ostarine side-effects is that they are mild compared to other SARMs.
You won’t need to use a SARMs PCT in most cases. This is a supportive supplement you take during a cycle break, to help restore testosterone levels. But as Ostarine is quite mild, it does not seem to have much impact on your testosterone levels.
However, the caveat to that is that your cycle length and dose will affect this. The thing to do is to make sure you are aware of the signals of low testosterone and have a PCT on hand for the end of the cycle, should you need it.
Especially at higher doses, mild side-effects from Ostarine might be encountered. But these are generally minor nausea, headaches, and muscle pain.
However, I want to address muscle pain specifically. Because SARMs are unnaturally bulking your muscles, the rapid growth can cause pain. Also, the ligaments around them, can’t grow as quickly, so they can’t cope with the sudden bulk increase, which creates the potential for discomfort.
Ostarine Vs Lingradol
So as you know, Ostarine is probably the mildest SARM, and great for beginners, or those who want a steady increase, with the least potential for risk.
But how does Ostarine stack up Vs Lingradol (LGD-4033)?
The first thing is that some people report Lingradol can cause water retention, bloating. However, I’ve never seen that, and it could just be poor diet structure that is causing it, or even that they are just susceptible to that sort of thing.
In terms of performance, there are basically two areas to look at, cutting and muscle building.
- For cutting, most people are saying that they are getting better results using Ostarine
- For muscle building, the consensus seems to be Lingradol is better
Lingradol is in my opinion slightly more powerful than Ostarine, and better for building bulk.
However, on the flip side, it’s also more suppressive. You will definitely need a PCT supplement if you are choosing Lingradol over Ostarine.
But they do make a very good stack. The combination of cutting and building, while still keeping side-effects down, can produce incredible results.
Best Place To Buy Ostarine Online
The problem with all SARMs, in fact, all regulated products, is that they aren’t policed in any way.
You may have read the horror stories online, where testing has been done on SARMs products and found as little as 50% purity. In some cases, people have bought, and used, powder labeled as a SARM, but it actually not contains any at all.
So finding the best place to buy Ostarine is all about finding trusted companies who sell it with a guarantee of purity. That purity needs to be backed up by independent lab test results, that they make freely available.
In my experience, I’ve only found pure Ostarine MK-2866 for sale in the USA from a couple of reliable sources:
Thankfully, another retailer who makes that possible is a high-quality company called
These guys are definitely the best places to buy Ostarine that’s almost completely pure. No SARM is 100% pure, but lab grade materials are usually over 99% pure. Just look at the website and you’ll see that this is a serious venture, who take analysis and quality incredibly serious, devoting whole sections of their website to the processes they follow.
Pricing is brilliant as well considering the quality though. 900 mg of Ostarine at a density of 30 mg/mL will only cost you just $35.99. They even do bulk discounts that are amazing. If you buy 20 bottles you’ll only pay $21.59.
Now I’m not saying many people will want to buy that much, but if you’ve got a friend down the gym who is also interested in SARMs, or you know people who use them already, clubbing together could save you an absolute fortune. So considering both the quality and bulk discounts, Science.bio is definitely the best place to buy Ostarine from.
The second best place I found really high-quality Ostarine for sale is a web store of Proven Peptides. In terms of buying Ostarine, they are definitely one of the best places, because of the purity. 99.8% pure on average.
They have great quality Ostarine MK-2866 for sale, that’s well priced as well. You can get 15 ml for just $34.99. The concentration is 25 mg per ml of liquid.
You can view independent lab test reports about purity, and you get free shipping on orders over $75. Plus, you get a 30-day money back guarantee, which gives you extra peace of mind.
Sarms-for-sale.com (Umbrella Labs)
My third recommended vendor is Umbrella labs.
Plus the price is really good as well. A 30 ml bottle, will set you back $65.99. The concentration is 20 mg per ml of liquid. So it’s comparable in price to Proven Peptides, but it’s a slightly inferior concentration.
They have responsive customer service, plus free shipping on any order value in the continental USA, which is brilliant. On top of that, when you spend $200, you get 20% off, saving you a bundle.
Ostarine MK-2866 FAQs
What is Ostarine found in?
Ostarine is not found in anything natural, it is a man-made chemical designed to deal with the effects of muscle wasting conditions. In terms of how it can be found, it is screened for as part of drug testing for most sports where it is required.
Ostarine, and SARMs generally, will definitely be found if you are sent for drug screening as an athlete, or for any sporting activity where it is a requirement for participation. Additionally, you should be aware that supplements are not always labeled correctly.
For example, some products labeled as “legal steroids”, are actually SARMs, even though many are labeled purely as herbal. In addition, the name Ostarine my not be used at all, with it being referred to by an alphanumeric name of MK-2866, or Gtx-024.
How and when to take Ostarine?
Ostarine can be taken straight up as a powder, put in the mouth and then chased down with water. Or it can be taken within a liquid, these are usually pre-bought, as they are expertly constructed
In terms of when to take Ostarine, you can take it at any time of the day. But you should use a consistent time each day, to ensure 24 hours between each dose. An average dose is between 10-30mg per day.
Ostarine should also be taken in a cycle. A lot of people use a cycle of eight weeks using it, followed by four weeks off it. At lower doses, some people use 10 weeks, and two weeks off it. Part of how long you spend between cycles will depend on if you have any testosterone suppressive effects, which will mean using a PCT supplement, and longer recovery time.
How long does Ostarine take to work?
Most people report that they start to feel different after about two weeks of Ostarine. This will depend on the dose, but around 20mg per day does give a significant uplift in strength and energy within two weeks, and within a cycle of eight weeks, several pounds of lean muscle will be gained.
Over 2 x 8-week cycles, with a four-week break in between, alongside a proper diet and regular weights and cardio people report a significant cut in body fat, alongside maintenance, and often an increase in muscle tone as well, even if eating a deficit diet.
Where to buy Ostarine?
You should only ever consider buying Ostarine, or any other SARM, from a reputable retailer. But finding out what reputable means is far tougher than you would think.
It’s amazing in the USA there are so few places which sell pure Ostarine. But the way to tell is to look for independent lab testing, and for those results to be published on the website you buy Ostarine from.
If the company confident in the quality of its SARMs it will also offer a money back guarantee, plus have responsive customer service. Try out the customer service in advance if you aren’t sure, to make sure they know what they are talking about, and are actually based in the USA.
How long is Ostarine detectable?
Very little research has actually been done on SARMs generally. In terms of how long is Ostarine detectable specifically, again, no real research has been undertaken to conclude anything.
However, anecdotal evidence from people using it, suggests that its half-life is around 24 hours, meaning the amount of time for half of to be processed and exit the body.
Despite there is not much evidence, there are a few pointers as to how long it could be detectable in a drug test. The best of this evidence is that the USADA warns athletes that it Ostarine is detectable for up to 4 weeks after it was last consumed.
