One of the best tests I have ever used.... I feel, these days, no matter who you go through, with (very little exception )you never can really be 100%, about what you are getting . Very rarely, at least where I live...the bb'ing guys are oozing to rip eachother off. I don't know why it's like that,...but IMO, it sucks. On this board, though,... as a"message board" I only have good things to say about these guys. Seems most have a good character, and are genuine nice guys. (My opinion) Back to the point tho,... For many reasons, you may be cautious about your brand gear, ....maybe you don't know eachother, trust is an issue, or maybe underdosing, or even, counterfeit products come across you way it seems. Whatever the reason, until you get lucky with the right hook-up, (which could take years)stop second guessing, and I figure, at least take advantage of what you know & is avail. to you now. I have piece of mind knowing what I have, and granted I follow the procedure (which is not hard, but a little longer than some) my finished product will come out fine. (another similar example: fina) People who claim "infections" off the bat, from making your own gear,... usually know little/if anything about it, or have never tried themselves. (I say this usually, not everyone) But, it is a matter of preferance really. There is always a risk involved,...sure it is possible to get an abcess, or infection,...but the chances, and occurance of that happening is slim to none, if done properly, which is in fact not hard to carry out. You would have to be unsanitary, and screw up pretty bad. IMO. You take a risk with brand name gear as well. IMO, I would say to try it out, but research it, and know what you are doinf first! From then, form your own opinion afterwards, about what you want to keep doing/not do.
