Table of Contents

What is Ostarine?

Ostarine is also known as MK-2866 or Enobosarm. It is a SARM which is short for selective androgen receptor modulator. It mimics the effects of testosterone, by binding to the androgen receptors in specific types of tissue.

Research into MK-2866 started in the early 2000’s and it is currently in phase 3 of human trials. Although it has yet to be approved by the FDA for human consumption, it is highly popular among athletes and bodybuilders.

How does it work?

Just like other SARMs, Ostarine targets the androgen receptors (AR) in a similair fashion as androgenic anabolic steroids. But, unlike steroids it only targets the receptors in skeletal muscle and not in the organs.

As a result, it provides many of the benefits of steroids, including an increase in lean muscle mass. But it doesn’t have the unwanted side effects that come with the use of steroids.

What is MK-2866 used for?

Ostarine MK-2866 is used to prevent muscle and bone wasting diseases (and their potential treatments).

However, it is most popular among bodybuilders and athletes because of the benefits it has in the gym.

  1. Building muscle/muscle growth – Ostarine can do a lot more than prevent muscle loss/muscular dystrophy. It can also help you to gain lean muscle mass and reduce body fat.
  2. Lean muscle – When bodybuilding with MK-2866, you won’t experience the same amount of weight gain as with steroids. But you will gain strictly lean muscle mass, without the risk of water retention or gynaecomastia.
  3. Muscle recovery – this is particularly important for workouts because the faster you recover; the quicker you’ll be able to get back into the gym.
  4. Joints and tendons – its protective properties – namely its ability to guard your joints, tendons and bone tissues – have made this SARM particularly popular amongst athletes.
  5. Bone health – the loss of bone-protective sex hormones as we age can result in poor bone health and even osteoporosis. Increasing muscle mass can help to reduce the risk of bone fractures and ensure a speedy recovery.

Ostarine helps by mimicking testosterone in your muscles and bones, providing support to your skeletal system and in the healing of fractures. It is also beneficial in the prevention of bone diseases.

The effects of Ostarine and potential benefits

Ostarine is developed to mimic the effects of anabolic steroids but without the adverse side effects. It was initially intended to help people with muscle-wasting diseases like osteoporosis since it binds to the androgen receptors.

It didn’t take long before athletes and other gym fanatics discovered the benefits and it is currently the most popular SARM on the market.

We will discuss the effects and potential side effects of Ostarine.

Increase in muscle mass

Multiple studies have shown that Ostarine can increase lean muscle mass at dosages as low as 1mg per day. A recent study from 2020 showed that both MK-2866 and Ligandrol had shown positive effects of lean muscle mass.

When used during a caloric deficit, it helps to maintain muscle mass.

Improve strength and performance

Next to gaining muscle, most studies showed an improvement in physical performance as well.

Most users who took Ostarine for a cycle of 8-12 weeks noticed an increase in strength and also improved performance while working out.

Bone health

Ostarine has been developed for the treatment of osteoporosis and other conditions that cause loss of bone mass. MK-2866 is praised because it prevents bone loss by increasing bone mineral density.

It has a positive effect on bone health by increasing bone mineral density.

What are the side effects of Ostarine?

One of the major reasons why Ostarine is so popular, is because it is the mildest SARM currently on the market. Most users that use MK-2866 do not experience any side effects.

Nevertheless, researchers and other users noticed side effects while using MK-2866. Below you will find the most known side-effects:

Testosterone suppression

As we mentioned before, MK-2866 is the mildest of all the SARMs. While it is less suppressive than steroids and even other SARMs, it may still cause a certain amount of testosterone suppression.

Testosterone levels will usually return to baseline in a short amount of time but many users choose to take some sort of PCT.

Ostarine Dosage and cycle length

During clinical trials, MK-2866 proved to be effective even in a dosage as low as 1 mg. However, the dosages used by bodybuilders and athletes are a lot higher, ranging from 5 to 30 mg per day.

The most common dose for Ostarine is 10 mg per day for women and 20 mg per day for men.

The average cycle length for Ostarine is 8 to 12 weeks.

When to take Ostarine?

Because MK-2866 has a half-life of 24 hours, it is suffient to take it once a day. It doesn’t really matter at what time it is used during the day.

Some users prefer to split the dosage into two parts, taking half of the dose in the morning and half in the evening.
