I did a 3 bottle run, 6 caps off days, 9 caps workout days, after 3-4 weeks strength jumped about 10%, which went away about 2-3 weeks after stopping. Perhaps the strength boost is neurological.
But you cannot put a lot value on my experience of the strength dropping off after till you hear from more people experiencing the same as my strength could’ve dropped from a number of things, for example fatigue due to lifting 10% heavier weights for several weeks in a row
Strength fluctuates, it peaks and dips, like many things in life. It was fun to be on it anyway!
