Honestly though,
L theanine is the bomb for skating and life in general. Literally no side effects and it chills you right the fuck out. Doesnt get you high but you just feel awesome. And its just an amino acid found in grean tea, doesnt really interact with anything accept alcohol. 5 beers youll be on cloud 9 and wake up feeling like you drank 15. Works on gaba system like benzos, phenibut and alcohol
