I dont give a shit what anyone else says. If you have any doubt whether your stuff is working or not, its probably seriously underdosed or bunk. I dont care if you know someone running the same stuff/batch. There is way too much of this crap going around, and people are going crazy trying to figure out why they are not getting results. I will say this again. There should be no doubt whatever if your stuff is legitt. Anyone that thinks it is something else is either bias or ill informed. I have gotten legit stuff from a place and ordered the very same thing a few months later and it was junk. There is no question, no substitute, PERIOD.
