I finally got my order from poppersaroma. I picked 3 mystery bottles as they were less than 5 bucks for 10ml and it seemed like a good deal. So 2 of them were amyl and one was a propyl. I decided to go ahead and try the propyl out. I already like to mix my sniffs up between butyl and amyl so that's what I did. A few hits of each and I was totally in the zone. Took my biggest dildo that I had barely been capable of using all the way to the hilt. It was totally a great experience. I did notice after about an hour though the green spot people talk about and that did concern me a bit so I ended the session.

So am I asking for trouble if I continue to use the propyl some of the time?

As for the amyl. I really liked it better than the twist beast stuff. Definitely hits hard and has a much more pleasant aroma. The propyl smells just like sprite or something to that effect and made it very easy to take a long pull. I typically use in goon sessions for 1-2 hour periods at least 3 times a week. I couldn't believe how much of a pure slut these new ones made me though..
