Question 1

Is MK2866 legal in Canada?

Accepted Answer

MK2866 - Ostarine is not approved by Health Canada or any other regulatory agency for human use and is not sold for human consumption. It may be lawfully supplied and purchased in Canada as a research chemical for laboratory and educational use only. It is also banned in sport by WADA.

Question 2

How does Ostarine differ from anabolic steroids?

Accepted Answer

Ostarine is a non-steroidal selective androgen receptor modulator. Instead of broadly stimulating all androgen-responsive tissue, it induces a tissue-selective AR conformation that drives anabolic activity in muscle and bone while producing minimal androgenic stimulation in the prostate and other reproductive tissues, and it does not aromatise to estrogen.1

Question 3

How does it compare with other SARMs?

Accepted Answer

Ostarine is generally regarded as one of the milder, most clinically studied SARMs. Researchers often benchmark it against more potent options such as LGD-4033 - Ligandrol and RAD 140 – Testolone, or against the myostatin-pathway compound YK11 - Myostine.

Question 4

What does the clinical research show?

Accepted Answer

Across randomised human trials, enobosarm produced dose-dependent, statistically significant increases in total lean body mass and signals of improved physical function, and was generally well tolerated over the study periods.2 More recent work has also explored AR agonism in advanced breast cancer.3
