I started to use Pre-Workout again because of tiredness after work and I noticed a thing I also had the last time.
The first drink of Pre-Workout I took gave me a feeling of hitting the juicy PRs for sure and the training went really good.
The next day I took Pre my lips and skin did tingle but the PE I felt in day 1 didn’t really came.
I used the Pre until it was empty and forgott about it.
2 Weeks ago I decided to give it another try… and the exact same course of events I described befor took place.
Is there some sience behind this or am I just expecting too much from a simple Pre-Workout?
