The Bodda Getta

Here is the guy I listen to. Muscle Fuel from Advocare as pre-workout, Mass Impact for building, and Post Workout Recovery for after the workout. There is also a BCAA product that is really good.
It is what I trust.

Advocare stuff is all overpriced. If you like it and don't mind spending 10x + what it would cost elsewhere, then go for it. However, I've talked a few friends out of Advocare and saved them a ton of money.

As far as the Muscle Fuel product...it isn't anything special. Advocare is great at marketing, and finding "experts" to promote their product...but if you look at what the key ingredients are, you can find them in almost any pre-workout supplement. Here is what is in muscle fuel: Creatine, D-ribose, calcium pyruvate, L-arginine, glycine, L-citrulline, vitamin A, vitamin C, vitamin B-12, folic acid, pantothenic acid (B-5), magnesium, zinc, chromium, sodium, potassium, green tea extract, caffeine.

In the video you reference, the PHD cites a study of improved performance and endurance taking muscle fuel. You can find 100's of studies that show similar results - i.e. increased performance and endurance with creatine alone. I could buy a 6 month supply of creatine for what it would cost for 10 pouches of muscle fuel.

All of this is just advice...go do whatever the heck you wanna do :)
