Clen while adding mass???

Starting a super mass cycle next week and I am wondering if it would be OK to take clen two weeks on two weeks off during my entire ten week mass cycle? Or should I wait until the end of the mass cycle to start clen? If I do run it during my cycle will the clen hinder my mass gains?

Thanks for the advice

I would go forward with the mass cycle and once your done with your clomid back, you can start a clen cycle to dump some fat (along with cardio)

Build when your building and cut when your cutting. this will save ya alot of time. =)

save the clen for cutting fat at the end. It will also help maintain muscle post cycle because it has an anti-catabolic effect.
