Spreadsheets FTW . I bulk pre-mix everything but the Caffeine, Citruline, and Gatorade.
The Caffeine comes in capsules; so I just pop one with the drink.
I don’t always want the Citruline; so I leave that out, too.
I also leave out the Gatorade, because sometimes I mix everything into a “smoothie” instead.
So once a week, I take my pre-mix, and add the Citruline and/or gatorade depending on my expected workouts. Takes about 5 minutes once ya get the hang of it.
Even the bulk mixing doesn’t take long at all. The fun part is when I decide to add a new supplement to an existing mix, which takes a little math (and another spreadsheet, lol).
