I make my own most of the time.
I do like the PES approach with ergonine and prolific though, because it questions the paradigm of preworkouts and asks a fundamental question that most of the industry completely misses.
What is a preworkout supposed to be?
A preworkout should ideally consist entirely of ingredients that are of specific acute benefit to your workout context, and whose dosing is most effective before a workout.
This list of ingredients is a lot shorter than most people probably think, and there’s quite a few ingredients commonly present in preworkouts that pose one or more of several issues:
- Prone to causing GI Distress
- Better absorbed with other nutrients alongside a meal
- More likely to end up being used for gluconeogenesis than muscle building
- Just don’t have benefits that are not acute/timing related
Ingredients that do not directly contribute to your workout do not belong in your preworkout.
