The Performance Optimizer (below and on the right in the collective picture) is to be used pre-workout. Even though I wasn't supposed to try something new on a race day, I had a packet before my recent half-marathon.
When mixed with water as indicated, the powder kind of looked like that brownish stuff that doctors use to sanitize skin (peroxide??), which was off-putting. However, the taste was slightly of berries and not bad, and honestly, its slight caffeine content and electrolytes seemed to have helped me during the earlier parts of the race.
On the left in the above picture is the Performance Protein. I took a scoop in a bottle and added water to it after the race for muscle-repair. I shook up the greenish powder, and to my great dismay, I didn't like it at all. I REALLY wanted to like it, too, because as you can see near the bottom of this post, it is nutritionally wonderful (20g of protein for 100 calories and lots of plant-y goodness).
Something about the spirulina made me gag, and it smelled like borderline spoiled milk. This could just be me and my individual tastebuds talking, though, so since this is an otherwise great, gluten-free powder, this might work for you. However, for me, I ended up spilling it all over my lap and seatbelt the first time I drank it in the car and gagged.
I have been using the Performance Optimizer during my long runs, and so far they have worked pretty well. I feel like I actually get a second wind if I drink enough of it.
However, I don't know what to do with the protein. "The Ukrainian" asked me to leave the jar behind so he can try it, as he currently consumes whey protein.
