Muwhaha last year we made a complete breakfast meal with 33% of all nutrients a person needs with coffee flavor, caffeine and beta alanine called Joylent Wake Up.
Today Soylent released a similar product called Soylent Coffiest. A complete meal with 20% of all nutrients a person needs, caffeine and L-theanine
I find it really cool that we are on the same track. The Wake Up has been very popular for us so I think it will do great for them too. For more info check their blog about it: http://blog.soylent.com/post/148692318597/be-a-breakfast-pioneer-with-coffiest
I also recommend watching their entertaining Youtube ad:
Soylent is only available in the US and Canada
Joylent is mostly popular in Europe but also ships to US and Canada
