My personal experience with SRY has been great. Does SRY have some somewhat questionable stuff in their history? Yes. However, much of that stuff is due to the great scrutiny that SRY is under along with SRY's stupid initial reactions to incidents. It seems to me that folks have been quite overly critical of SRY just like I used to read incessant rants against Cain. Amo/BFF/Binh and PGB do not have similar questionable stuff as does SRY. Arguably SSA has less of that stuff recently, however, it seems to me that SRY has always eventually made things right. I did wonder afterwards whether I should have ordered from SSA instead of SRY. I should point out that the one time that I used SSA, SSA was fine. The only place I'll trash is QSC since Tracy still hasn't delivered my order from early January. My recommendation if someone wants a recommendation as to who to buy from is to buy from someone that you hear about a great deal and that gets tested regularly. Inevitably you will hear some bad things about that vendor. Listen to the stuff, but expect some negative things. I do suspect Amo and PGB are more dependable than most of the others, but they are quite pricey. Cain is probably there in dependability too; I'm going off what I have heard from users as since I have never personally ordered from Cain. I also once ordered from a pricey domestic vendor whose name eludes me that is supposed to have an excellent reputation despite charging ridiculous prices for single vials.
