absolutely you can bro.. 677 is non suppressive and you can run it continuously for at least a year... i would highly recommend that time frame... the very best mk677 you can find is at www.sarmsx.com
That's exactly how you want to use it bro. Keep MK677 going right through pct and beyond. It is best at 6 months to a year and just keeps getting better the longer you run it. Its truly an awesome compound and quite possibly my new favorite sarm, though I'm very partial to GW as well

its very difficult to say when they all have so many damn good qualities... i have been saying for quite some time that 677 will be everyones favorite... mine personally will always be gw but what 677 can do, its going to be the favorite of many for sure...
