Detailed Product Information
MK-2866 Builds Muscle And Burns Fat
With multiple published human trials under its belt, MK-2866 (also called ostarine) is one of the best-studied SARMs. Those studies found powerful results, too. Ostarine shows no meaningful side effects and is very effective at building muscle.
Elderly men and women who took modest doses of ostarine for 12 weeks grew 3 pounds of muscle and lost a pound of fat, with no changes to diet or exercise. Cancer patients saw nearly identical results along a similar timeframe. There were no side effects in either study.
A pound of muscle a month is about what you would expect with a solid workout routine – but the people taking ostarine in these studies weren’t exercising. Combining the two would be even more powerful, in theory. Pretty impressive.
Side effects of MK-2866
The studies found no side effects. Anecdotally, however, people report short-term testosterone suppression when they take high doses of ostarine for 8-12 weeks. Testosterone rebounded to normal levels within a couple weeks after they stop. The dosage I discuss below is far lower and for a shorter amount of time, but there’s still a risk of short-term T suppression, and possibly other side effects researchers don’t know about yet.
How to dose MK-2866
There haven’t been official dose recommendations for SARMs because they’re so new. The doses in this article are all conservative, and based what on studies and anecdotal reports show to work.
For ostarine, 15-20mg daily for 6 weeks. Time of day doesn’t matter. To be cautious, take at least 6 weeks off so your system balances out before starting another cycle. Ostarine, along with the other SARMs on this list, seems to pair best with regular exercise like lifting and HIIT.
