I have found multiple sites selling Clen. Where do I buy it to not get ripped off? I'd like to drop about 30 pounds and I wanted to do a 12 week cycle. I also wanted to do every 3rd week with Benadryl. I'm also unsure of how much to buy and how much to take. Is it possible for me to drop 30 pounds in 12 weeks with Clen? Any info will be helpful!! Thanks!
