I started and vapor yesterday. I decided on both of them because spirodex is more marketed as an all day feel good type of burner and vaport as more of a pre wo.
Let me tell you i love spirodex. It gave me a good feeling no crash no jitters I wasn't overly hot nice clean energy. but the appetite supression was AMAZING.
I took 1 vapor later in the afternoon about 5 hour and I could tell it was more of a thermo get up and go. but I was happy with it also i think it's good for pre cardio. I know alot of people don't like gaspari but it's never let me down and I have used alot of products and have a good track record here on the board. for the price these are two good products i'll let you know again in a few days. as questions please feel free.
