Yooo, thank you! We are always following the shape, I guess it never ends xD
Maltodextrin comes from corn if I'm no wrong; it's also sweet as fuck, and great to fuel the body during endurance sports. Fructose is also important.
I take creatine 3-4mg every morning with breakfast just to keep storage near the upper limit. It helps with short and super intense efforts. I noticed after taking it for a month that I'm fresher after the gym, not sure if it's placebo or a real positive effect.
Lastly I use our favorite: whey protein
