Im currently taking Dymatize xpand and Scivation xtend as supps. Im about to start a test e cycle and wanted to know if I should keep using my supps during the cycle. The xpand is a stim creatine/bcaa/arginine mix and the xtend is BCAA's. I understand maybe dropping the xpand due to BP but is there a reason to not use the xtend. Thanks
