Post in the AAS forum, there is a handful of guys over there who give quality advice. My advice is to research it enough that you can tell who is giving good advice and who is cut and pasting from a book or just simply agreeing with a previous post to sound cool, lol.
In my opinion, Clen is about the worst shit somebody can do to themselves and I'll never understand why people use it, but people continue to use it. Asking for opinions on a forum is a good idea, but if you don't know enough about something to be able to filter through the crap and make an educated decision on your own, then ya deserve whatever ya get.
