Read around, I assure you that every possible facet of the GVG vs. VG vs. Anything Else debate has been written and rewritten on this forum. Well, regardless, the GVG is the best. You may not want to invest in it before you know that you really love the molecule, but it's the best. With changa, though, you can get away with a bong for now...
When that thread was referring to a batch of changa, that 1g batch was meant to contain however many doses, not just a single one. Making one dose at a time would be a pain in the butt, number one, and secondly, I highly doubt that the meagre 30mg DMT worth' of changa you may make will be anywhere near enough to satisfy your curiosity the first time; chances are you'll smoke more than that trying to get your technique straight.
And the reason that a 1:1 ratio by weight is preferable is because if you have too much caapi leaf, it can become difficult to get it all in quickly enough for a strong experience. Weigh it out!
