You may feel overheated but Beta-alanine is actually great for drop sets in terms of stamina / recovery.It's not good for big drop sets though. It actually limited my reps bc I felt overheated.
Straight from the write-up:
-Beta-alanine increases muscle carnosine content which better outputs performance in exercises that range between 1-2 minutes. Beta-alanine has the capacity for users to push that extra rep or two and increase both your peak and mean power output tremendously, whether you’re a bodybuilder or an endurance athlete.
-Research shows that during high intensity interval training Beta-Alanine increases strength, power, endurance, speed, and also reduces neuromuscular fatigue which enhances the users ability to recover. Beta-Alanine has also been shown to increase lean muscle mass.
