You do realize you're already taking a test booster right
Its probably not needed and not gonna give you any real advantages. I know some test boosters make me aggressive as hell even more so though than when I'm on cycle and that can give you a slight advantage in the gym (and bedroom), but won't yield much effect in terms of recovery or feed efficiency.
Your stack looks pretty solid I would swap out the dexyfen for ec and the protien shakes for a bcaa drink I like the bulk modern bcaa cause its cheap or you could just do micronized bcaas and sugar free koolaid probably make some tweaks to your diet and if your not already doing cardio, you would be surprised at how much it your stamina can increase by just forcing yourself you to do it after a week or 2 the amount of time it takes to catch you're breath after you're hardest sets will be cut in half.
