I think you might have missed my point. I'm well aware of how to DIY... I just suck at it. Unless my favorite vendors' revealed their recipes and gave an exact list of ingredients, ratios, the names of the manufacturers of said ingredients, as well as a "Step 1, do this. Step 2, do this," etc., I'll NEVER be able to recreate the juices I've come to love so much.
And yes, to anyone suggesting it, I have multiple tools, apps, and calculators for DIYing ejuice. Every time I've tried, they sucked.
