The serving size for this is huge, but I'm not going to list this as a pro or a con- it just is what it is. When this first arrived I was curious why it came in such a big tub but then saw the big 31 gram scoop inside.

Mixing was very easy. It smells odd in the tub and looks like sawdust. Despite the cloudiness it disperses very well. Since it contains a couple grams of whey the mixture is a bit milky and foamy.

Taste: Not bad. Here is where XF falls short- they only made 1 flavor, lemon. On the bright side it is very tolerable. Not the best like I expect all of XF's flavors to be, but for being a preworkout they did a very good job. No bitterness, chalkiness or aftertaste. It is quite dry tasting I think due to the fact that it has pomengranate extract in it.

Effect: No jitters or racing heart. It comes on very clean & sharp, gets you worked into a good sweat and laser-sharp focus. I set personal records while on this stuff.

I have said this many, many times, I have utmost respect for the XF team. They are good at everything they do and they excel in taste above and beyond. They are on the top of my list supplement wise and it would break my heart if they ever deviated from it.

In the time I used this, I was trying to lose weight and push endurance. Not being able to use Arginine, I was looking for a pump mix. This is kinda good for that but I wouldn't use it after this. The Ingredients were really good, but I was only using one scoop, maybe using more than one would help someone training harder. I did gain muscle and also weight.
Not the best for fat burning.
