I actually do have a first one. those used to do the rounds last year already but a friend of mine has seen them again last weeked.
hexagonal PP (philipp plein) pills. they exist in various colors and judging by testing sites they are all really strong - between 150 and 200mg MDMA. which means taking an entire one will definitely be too much (unless you're 120kg weight and have a tolerance of someone taking MDMA weekend in weekend out for years).
you know the rule, start with a half...or with pills like that even a quarter will do, you can always take another quarter later.
