While making your own can be great for cost effectiveness, it can really become a pain (lots of bottles/baggs/etc, constantly mixing, etc). one of the other issues is that as newer ingredients come out, you would ahve to constantly buy more (and buying in bulk isnt always possible for many of the branded ingredients - at least without insane amounts designed for manufacturing).
That said, my suggestion would be CEL Super Swole - its an all-encompassing pump based pre that has a boatload of research backed, patented ingredients that will give you exactly what you're looking for. And if you change your mind or somehtign newer tickles your fancy, you're not tied to pounds of bulk ingredients that you still have to use up ha.
