masteron is a great compound for cutting. for me, its side effects are low. i do not expereince dry joints nor does it dramatically effect my cholesterol like winstrol. find it helps bring out a certain grainy quality as well as increases my aggression in the gym, effecting my strength and drive. it also is great for sex drive. i have never used it in a bulk, but i feel that the strength and aggression would only add to your cycle. i would suggest starting with masteron prop. mast e is also a good compound, but i personally dont feel quite the same punch on it. i would start using it in the second half of your cycle around wks 11-18, add in masteron at either 50mg ED or 100mg EOD.
