yes, you can certainly do it that way or you can go 1-10 because if you run a 12 week cycle, you would still need two weeks before pct starts after your 12 weeks..
so your cycle would be weeks 1-12, then weeks 13 and 14 you wait for esters to clear and start pct week 15.. so if you stop mk2866 at week 10, then you are good to go when pct actually starts... you could also use rad140 on cycle instead of mk2866 as well
