Have you done it?
Yes, it only lasts for 2-3 hours, but the RUSH is amazing. It hits instantly and like a train the first few times you do it lol. You start peaking within 2-3 minutes of it going up.
One of my best rolls, I busted open a molly capsule, crushed it and chopped it up real fine. I made a nice long even rail about 12 cm in length, .5cm in height and .75cm in width. I came up from the line trembling with flutter vision and teeth chattering, breathing VERY heavily and quickly. I was so fucked up, I didn't even have the coordination to do the basic moves spinning poi lol.
After about an hour and a half, I did the same with my other capsule, but I gave a friend of mine about a 1/6 of it.
Another way I would do it, is I would snort one and then maybe eat one, then eat another 2 hours later. I'd do the bump to get me up, and then the swallowed one was to keep it going.
