Hi guys! i have 33 amps of Galenika which should last me for fifteen weeks with an additional 3 amps left if i were to run 500mg weekly. would frontloading be of any benefit? also i am not sure but there are several numbers on the amps 1534 0407 0412. is that a batch number or the experation code? if its expired is it still safe to run?sorry for the many Q's. thanks
