not because it would neglect the affects of zma while your body is being filled with a rise in testosterone, but i wouldnt run zma side by side with your 1-test/4ad use. What would be more ideal is start the zma towards the end of your cyle, instead of waiting til your run is over. If your usage of t1-pro lasts your 4 weeks, start up the zma at the end of 3rd week so you will have a nice and smooth transition from your cycle to the post. and keep using it for the post you have planned, adding in the fuzu a week after zma. I have started my post cycle supps the last 3 days of my cycles...in your case, extend that to a week but again, i wouldnt run them side by side.....you will be getting great results with the t1pro alone, with a strong diet and training.
