I like the blog/website a lot as it includes a few different recipes that I plan on making soon. Skratch labs is good - I have had the lemon lime flavor and may order some more. It's more expensive than the big tubs of Cytomax you can buy online, but apparently it's more natural. I don't know how it compared to HEED, but I like having calories on the bike and I think HEED doesn't really have any, or at least the tablets do not.
