Don't but paradeca or decavar. It's a huge ripoff and i fell right into it. They use their scientific jargon to lure you in. I bought one bottle of paradeca(480cc) and one bottle of decavar(120cc) and stacked them. I took triple the recommended dose hoping to see some good results. Over the 5 weeks i only gained 3 pounds and that very well might have been because i had so much faith that it would work. It also tastes pretty bad and don't ya know they sugggest you hold it in your mouth for 3 minutes. I am just warning everyone not to buy it.
oh and buy the way my experience cost me 260$. Yeah i fell like ramming my head into a wall everytime i think about it
