I've heard nothing but good things about sydgroup from other bros and in mags. Here's what a buddy from another board told me about his experience with it...
"The guy that actually started making that stuff lived ion Puerto Penasco mexico which is only 4hrs away from me. He originally got the license from Jurox to use their product but put his label on it. That was a very long time ago. Since then, he has moved to Mexico city where he started making his product himself and started dist. it throughout mexico. Since then it has become pretty popular. I have personally had great luck with the stuff since the beginning."
Also, it's cheaper than QV but I still love QV. Their Deca 300 is some potent sh!t!
