Are you really that uneducated with AAS? MAG-10 is a prohormone and a strong one at that...and a prohormone is a steroid whether you'd like to hear it or not. Compared to "real" steroids though...andro products are considered relatively weak...which isnt to say they dont work (from what i hear they do). That being said...i wouldnt say its HORRIBLE to use Alpha Male or some other pro testosterone formulation as PCT for MAG-10...but its not the best option for PCT.
Sure majority will get away with doing this because as i stated before, andro supps including MAG-10 are rlatively weak compared to "real" steroids. The point still remains that it does have an effect on suppressing test level, just as "real" steroids, and what do most people use as PCT for "real" steroids? CLOMID!!! and also nolvadex...but nolvadex is more for preventing/reducing gyno and clomid is supposedly better for bringing T levels back to normal.
That being said...if its you cant find clomids and/or nolvadex because of various reasons (i.e. money, scarcity..whatever)then id suffice to say that a pro test formula should do for PCT...preferably Alpha Male.
