I would say start off with half, because for someone who doesn't do this very often 30mg of any ty king could be a bit too much. Also if you don't get to much out of it tho is time then just take a whole next time!! I hope you have fun! Also pro tip have lots of snacks and a good show, because if you start getting over stimulated then both of those will help. Be safe too!!
not exactly less powerful, the highs tend to be shorter and shittier. definitely start with half if you’re not comfortable doing more! also they’re not really regulated so most people tend to avoid it. ur safest bet is always to cop from a dispo (coming from someone who does not cop at the dispo)
