u/I-Im-C-Cold

My roommate has some lsd tabs and he invited me to try some, I’ve been interested in lsd for a very long time and have done a lot of research on it. There’s 2 reasons I’m skeptical. I’ve never done it before, and my roommate doesn’t know how many ugs are on a tab. I would really like to try it maybe around 45-50 ug but I don’t wanna risk it’s all random and 1 tab turns out to be 100+ or something, if you got any advice please comment below, he planned on taking it tomorrow so if I can get any input before then I’d appreciate it!
