Ostarine is an amazing selective androgen receptor modulator (SARM) which helps users increase lean muscle mass, fight muscle wasting, reduce body fat, and it's also been shown to be very safe in studies.
But, what company has the best Ostarine? In the SARMs world, tons of companies selling Ostarine MK 2866 are actually just selling fake products spiked with steroids to mimic the effects of Ostarine.
So, how do you know who to trust? Well, I've been in this industry for over 10 years now, and have spent at least $5,000 testing Ostarine from over 13+ companies.
With that in mind, I've boiled down this list to just 3 companies that are known for selling the highest quality MK 2866 on the market, so pure it can be used for laboratory research use. Here we go.
Brief Ostarine Overview

Whether you're buying Ostarine for human consumption or for laboratory research use, let's take a quick look at Ostarine MK 2866, the most popular selective androgen receptor modulator that there is.
Ostarine (or MK-2866) is a SARM that was developed to increase the total lean body mass and bone volume density in cancer patients suffering from muscle wasting and loss of physical function.

It was researched on elderly test subjects, including healthy elderly men, and researchers found it showed big promise for increasing muscle mass, improving bone density, and much more.
Ostarine Benefits Overview:

Ostarine quickly binds to your androgen receptors, signaling your body to start improving physical function, packing on muscle mass, and growing new muscle and bone tissue, making it an excellent choice for any bodybuilder trying to pack on some muscle mass and bulk up.

Buying Ostarine FAQ's

We've been in this industry for a while now, and we hate to say it, but most companies lie about the SARMs they have for sale online. They'll say it's “Ostarine MK 2866” but load it up with cheap prohormones to save costs, that just end up giving you gyno and side effects.

Which Company Has the Best Ostarine?
Overall, if you want to buy SARMs like Ostarine, we recommend Chemyo. Their MK 2866 Ostarine for sale is always of the utmost quality, and has stayed consistent over the past 5 years or so.
Every cycle I do from Chemyo always leads to huge increases in lean body mass, lower overall fat mass, and I haven't noticed any negative effects on my blood glucose, heart health, reproductive organs, testosterone levels, or anything else, so I know they aren't selling fake, dangerous prohormones.
Is Ostarine the Best Selective Androgen Receptor Modulator?
There's really no best SARM, because it's going to depend on your goals. For example, if you want to improve heart health and total cholesterol levels, Cardarine (GW-501516) is the best SARM for that.
If your main goal is to simply build muscle mass, accelerate fat loss, and prevent any muscle loss, then Ostarine is a great choice for you. Ostarine MK 2866 is a fairly mild SARM that is great for beginners.
In fact, if you haven't already, read our article on the best SARMs for beginners so you can find one that's right for you and your own individual goals.
Is Ostarine Good for Lean Muscle Mass?
Every clinical trial for either a rat model or human consumption model has shown that the trial's subjects all gained large amounts of muscle, especially on higher doses of Ostarine.
According to clinical trials, Ostarine has the ability to selectively bind to androgen receptors in the body, similar to anabolic steroids, except their selective basis leads to far lower incidences of side effects.
Many clinical trials have confirmed the fat mass shredding, bone healing, and muscle building capabilities of Ostarine. Just eight weeks is more than enough for your first MK 2866 cycle, although running a 12-week cycle of Ostarine is an option as well depending on how much muscle you want to build.
How Much Ostarine Should I Take?
Many companies stock Ostarine dosed at 25mg ml which means that one full dropper (one ml) has 25mg of Ostarine. SARMs (including MK 2866) are dosed in milligrams per milliliter.
Generally speaking, for beginners, just one full dropper of Ostarine each day is enough. Depending on the company this will either be 10mg per day or 25mg per day. If you want more information, we recommend you read our full Ostarine Dosage Guide to find the best dose for your own needs.
Are There Any Side Effects?
MK 2866 Ostarine is very well known for being safe, which is why Ostarine treatment is being explored for its potential ability to help cancer patients and even just healthy elderly men build more muscle.
There are some minor side effects to be aware of, which you can read about in our full write up on Ostarine Side Effects, but overall Ostarine is considered to be one of the safest SARMs out there.
Conclusion
