Summary
This pre-workout supplement contains beneficial ingredients like L-citrulline, CarnoSyn beta-alanine, and alpha-GPC, which support exercise performance and cognitive function. The use of natural sweeteners such as monk fruit extract and Rebaudioside M is a positive aspect, avoiding artificial sweeteners. However, the inclusion of 'natural flavors' without transparency slightly detracts from the overall formulation quality.
