Hi! I’m a 15-year-old boy and I would like to try some PWO. I wouldn’t wanna go super high stim so I found one with per 10g 2500mg L-Citrulline, 1350mg L-Arginine, 1250mg Beta-Alanine, 1700mg L-Leucine, 850mg L-Isoleucine, 850mg L-Valine, 100mg Caffeine, 6mg Magnesium. Would this be a good pwo for a first time try and is pwo even safe for 15-years-old?
