I took 400mg, started with 200 but quickly added all the rest, i suggest to start with 400 as lower doses dont do much.
No big effects on my heartrate and stuff, bp dunno didnt measure it, no insomnia, its actually pretty sedating, i was lying on the cough for most of the time, then i added in some lines of ket, low dose of 2CD (not psychedelic) and some GBL, absolute bliss, but it needed more stimulation, so wish i had amp back then.
It lasted around 6 hours.
Tbh if you have acces to mdma, go for that, its a good combo drug tough.
