this is a tuff one because if you search it and get thrown into a sarm forum; especially one ran by the guy who gave the superman logo a bad name and has a head of lettuce and looks like he is one of those kids who you send money to so they can eat a sandwich. That forum will blast the crap out of this and claim its filled with every PH under the sun.
ok, so worse case, you bought yourself a 3 week cycle of dmz (3 weeks cause if it is filled with a PH, most likely will be under dosed).
if I were you, I would focus more on the what to do when using, ie routines, diet etc vs the brand itself. your setting yourself up for a mind F on this and will be expecting the world and the 1 little doubt will snowball.
run it and at this point hope for the best
