I understand that you already started your PH cycle, so there is no point in directing you the other way. PH's are usually very liver toxic, so you will definitely need a good liver protection when taking them. N2Guard offers the most complete protection, as it has a lot of ingredients that other supplements don't have. For the next time, consider using SARMs - they have approximately the same results, but unlike PH's they don't have side effects, are not liver toxic, and are completely legal to buy.
