Common questions

What are the best supplements for performance?

By usage and evidence: Caffeine, Creatine Monohydrate, Whey Protein. 18 compounds here carry evidence level A, meaning the effect was studied directly rather than inferred.

How many supplements for performance can you take at once?

There is no fixed limit, but every added compound multiplies possible interactions. The compounds on this page have 203 documented interactions between them — check a pair before stacking it.

How long until supplements for performance start working?

Depends on the compound. Each page lists first effects and peak benefit windows separately, because the two differ by weeks for most compounds.
