Capsaicin is the active ingredient found in chilli peppers. Consumption of 12mg of purified capsaicin powder 45 minutes prior to resistance training increased the repetitions performed while simultaneously lowering RPE.

However, a previous study on repeated sprints showed no performance benefit
from capsaicin supplementation in the form of cayenne pepper and a substantial increase in stomach discomfort.

While capsaicin supplementation may eventually prove to be a useful ergogenic aid, given the potential to cause GI distress, we would recommend waiting until further research is published before supplementing with it.
