I did a redVW/Archie in melbourne last weekend.
I had two friends that split a VW and got nothing out of it.
The VW produced a great peak, happy, dancy, lovey, cept only really lasted for 2 hours for me. The archie went down after that at fucked me up properly for the next 4+ hours.
I'm still a bit wary about the Archie, my friends love em more than me. They are way powerful, and on the weekend when i was peaking, I would have these waves and rushes whereby the top of my head went numb, in a line down the middle, and my instinctive reaction was just to hold my head. I felt like i was close to flying. Last weekend was the only time i havn't hallucinated on these to some degree.
I had a great night, but a really bad comedown over the last 4 days (only just got over it) and the top of my head has been tingling in that spot for most of the time, I'm new at this, but it's been a bit unnerving.
Anyway thats just my 2c, most of it's stopped now
I wouldnt reccomend anyone double drop these, and I wouldnt offer them to a first timer either.
