Ostarin: MK-2866

MK-2866, also known as Ostarine or Enobosarm, is one of the best-studied SARMs. It is a non-steroidal selective androgen receptor modifier that strengthens muscle, bone, and tendons. It does not have the negative side effects associated with testosterone such as raising liver, kidney, and prostate enzymes. 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.
