i have to agree. i have done jins for the last year and switched to blue tops. they are definately just as strong if not stronger for half the price. no brainer.
So what does it mean when you have no sides at all?? I'm doing 6 ius a day and my wife is doing 4 (blue tops) and neither of us have noticed any sides (we have been on for several weeks). Purui is awesome and has great customer service, but I'm a bit worried about not noticing any effects.
