I'm not trying to be offensive, and that's great that you've established a size/ serving connection for two popular supplements, but CNW has 30 on their custom mixes pages. Let's also think outside the box for a minute: Not everyone knows how much to take nor will they all do the research to find out. If you don't make homebrewing feasible, you're losing business to people who are. This whole custom mix thing is new and innovative, and should draw in new customers, but it takes two to tango: they need to be educated first. Unfortunately, they're not going to be like you and me (who have been buying the bulk powders and mixing them ourselves), they're not going to do their research. If it's not feasible, they won't go for it. That's why I asked for the densities. It's a very good idea to have. I know it's not all about being EXACT with some of these, but if you don't even know a good rule of thumb with some of these it will at least point you in the right direction.
