MK-2866 (Ostarine) Review

Ostarine (MK-2866)The other day we got our hands on a very interesting SARM stack tried by one of the new members on the board. Male, mid 40s, recovering from a severely damaged shoulder (multiple rotator cuff tears, left latissimus, rhomboid) and was using MK-2866, also known as Ostarine (25 mg/day) and MK-677 25/mg a day for the past 12 weeks.

He reported some crazy gains. Firstly, he was back to lifting his ass off on the bench. No shoulder pain whatsoever. That’s no mean feat coming from an injury like that.

Secondly, he gained some 15 lbs. of lean muscle mass and dropped body fat by 4%.

He was so impressed with the results, that he wanted to cruise with the stack for the rest of the year.

Thankfully, we talked some sense into him and told him to take a few weeks off with a small PCT dose before restarting.

Coming to the cycle, it spurred a lot of inquiries about Ostarine or MK-2866 for its purported fat burning and muscle building effects. Most, were from middle aged guys looking for body recomposition.

So, here’s our two cents on this amazing compound that’s always been a favorite with bodybuilders and us.

What is Ostarine (MK-2866)?

Amanda Ribas sarmsOstraine or MK-2866 as it its often called, is a Selective Androgen Receptor Modulator or SARM that is widely used in bodybuilding and athletics. (Remember Amanda Ribas’s two-year suspension from UFC?)

Like most of its siblings, it was chance-discovered as a bodybuilding supplement. The intended use was to prevent muscle wasting caused due to cancer and other health conditions.

Along with earning the reputation of being one of the only SARMS that has been clinically tested on humans, Ostarine is also the most famous SARM of all times, because it was the bone of contention in a lawsuit filed by one health supplement manufacturer against another.

Controversies apart, it is immensely beneficial in any kind of fitness routine or athletic activity. And it is not because it helps users gain a lot of muscle while trimming fat. (Which is one of its innate qualities)

It’s because Ostarine will amplify recovery. (More on this later)

How to use Ostarine MK-2866

There are tons of ways in which you can use Ostarine.

You can use it alone in a 12-week cycle. You can stack it with other SARMS, the most notable ones being LGD-4033 and MK677.

You can even add it to your steroid cycle.

Irrespective of what your goal is, the maximum dosage that you’d want to take is 25 mg/day orally (Drops or powdered form)

Do not exceed this dose no matter what junk you read on the internet. People might even take 100 mg/day. But don’t be that guy who wants to add their name to the ‘overdose obituary’ section.

Stick to the recommended dose and with a good diet and regular lifting, you can gain up to 12 lbs. of lean mass. Even people who don’t follow a diet and exercise routine have gained at least 7 lbs. in 12 weeks while using Ostarine.

It has one of the longest half-life (24 hours) among all SARMS. So, you don’t need to divide your doses either. Just take one dose in the am.

What can you expect after using Ostarine?

Like we said, that depends on a lot of other things also. How frequently are you lifting? What are your long term goals? What about nutrition? Are you stacking it with other SARMS? Let’s say you have your diet and exercise figured out and are using MK-2866 as a standalone drug. Here are some of the results that you can expect. ostarine results

Muscle/Joint healing:

Ostarine is the bee’s knees for healing and recovery. Muscle soreness becomes a thing of the past even in low doses. We have had users walk into the gym after a backbreaking leg day like it’s their first day of lifting, ever. In normal circumstances, they would barely be able to walk. This quality of MK-2866 allows you to stretch beyond your normal lifting ability, especially for compound movements like squats and bench presses. A common problem with steroid usage is the fake sense of strength that it gives, which often leads to injury. Ostarine keeps you covered by speeding up healing like never before.

Lean Muscle Gains:

Ostarine is highly anabolic. With a good diet (calorie surplus) and workout routine, you will easily gain at least 8-10 lbs. of lean muscle mass. Results may vary mind you. There are some users who have gained as much as 15 lbs. of lean mass and have compared Ostarine to a Primobolan cycle. There have been others who have gained just 5 lbs. So, it would be fair to say that different people react differently to it. But 6-7 lbs. is a safe number to expect.


People compare Ostarine to Anavar often in terms of vascularity. Your veins start to bulge out like never before and it keeps improving as you progress in the cycle. It hits the peak around the 9th week or so and then stays consistent even during the PCT phase.

Fat Loss:

Cutting cycles can be a pain. You are eating in a deficit. Your body is already in a catabolic state. Your metabolism is probably dented. Secretion of important hormones like Insulin Growth Factor and Testosterone are severely depleted. This is when, a compound like MK-2866 can be immensely beneficial. It allows you to burn fat for fuel and preserves your hard earned muscle. It is this quality that has made it one of the best compounds for preventing muscle loss caused due to osteoporosis and cancer.

Is it completely safe for use?

Ostraine is a SARM. So, it selectively affects cellular receptors in the body. You will not experience the typical side effects that steroids give you.

  • You don’t need to worry about gynecomastia
  • No hair loss/ unwanted hair growth
  • It doesn’t cause virilization in females
  • No Roid rage

However, it still is a very powerful compound that when ingested, will cause some mild side effects.

Here are some of them.

  • It will cause mild suppression of your natural testosterone production.
  • It causes headaches, especially in the first few days of usage. If the headaches become unbearable, we recommend reducing the dose to half of what you are using, until your body is accustomed to the compound.
  • It does cause puffy nipples due to an increase in serum estradiol. However, this happens in very few users only who are extremely sensitive towards estrogen.

To ensure that you allow your body to heal normally, follow a regular PCT protocol after a 12-week cycle of MK 2866. Never extend your cycle beyond 12 weeks.

As is the case with most SARMS and even gear being sold in the grey/black market, there are only a handful of reputed sellers that you can trust.

Most of the stuff is junk and you have no idea of what chemicals/compounds you are ingesting into your system.
