MK2866 Ostarine 60 x 25mg

Ostarine (MK-2866) is a Selective Androgen Receptor Modulator or SARM for short. It's extremely effective at increasing lean body mass without any androgenic activity in non-skeletal muscle tissue.

By attaching itself to the androgen receptor and then activation it is alters the genes and increases protein synthesis which of course then builds muscle. This is the same mechanism that testosterone or steroids use to build muscle but MK-2866 does not cause the prostate to enlarge or any other secondary sexual organs.

Ostarine is the most anabolic SARM of them all, making it the original go-to for people looking to bulk up quickly without using steroids. When bulking, we frequently see people gain 5-7lbs, sometimes more, in a 6-week cycle. It can, however, be used for up to 8 weeks without experiencing the on-cycle side effects associated with steroid use.

Because of its ability to maintain muscle mass and strength during calorific deficits, ostarine can also be used during a cutting phase of training. Many people believe it has a nutrient partitioning effect, which explains why people lose fat while cycling.
