Ostarine Mk-2866

Ostarine (MK-2866) is a selective androgen receptor modulator. It was created by a company called GTx to help treat or avoid muscle wasting. It works by binding to androgen receptors within the human body in a similar manner as anabolic steroids.

Many users on bodybuilding forums have reported similar results to steroids when using Ostarine, but without the side effects often related with steroid usage.

Gtx has performed 8 scientific trials on Ostarine with around 600 subjects as well as 3 efficiency studies. A 4-month Phase IIb medical trial including 159 patients have shown a complete boost in total lean muscle mass compared to placebo and the secondary goal of increasing muscle strength.

For bodybuilders, Ostarine has shown to improve strength and lean muscle mass in short periods of time.

Benefits of Ostarine

It’s not uncommon for people using Ostarine to gain 3 to 6kgs of muscle from a 4-6 week cycle. Unlike steroids, HPTA suppression from Ostarine usage is very minimal. When using steroids, the body’s natural testosterone production gets shut down (HPTA suppression), this causes a number of side effects such as depression, erectile dysfunction and low self-esteem. Low testosterone levels also lead to loss of muscle mass, this is one of the reasons that many people lose a large part of their gains after stopping their steroid cycle. Due to Ostarines minimal HPTA suppression, it is much easier to maintain the muscle mass gained from the Ostarine cycle.

Some benefits include:

  • Increased strength
  • Faster muscle growth
  • Better endurance

Ostarine Dosage

Most people will often use around 20mg a day for 4 to 6 weeks. Some users choose to take much higher dosages, but this is not necessary and may be bad for you. Due to Ostarines long half-life (around 24 hours), the dose only needs to be taken once a day and does not need to be split up throughout the day.

Where to buy Ostarine

It must be noted that Ostarine is currently not FDA approved and is therefore only sold as a research chemical. This however does not stop people from using this product to get stronger and build muscle faster.
