This topic is an old one, but with the ever-changing nature of the supplement industry and experimentation/innovation, it is always salient.
Beowulf and I did some good experimenting back in the day, but for a coule years now, I have cut out the old pre-w/o cocktail. Now I want to revive it. Here is a list of what I used to use. I'd love to hear what you are mixing up or what particular ready-mix you have found that works great.
Thanks for your feeback.
