Has anyone had experience with NATURAL diet pill type supplements like Leptitox (bit.ly/leptitoxinfo)? I've previously tried many things including the Keto diet which didn't do much for me. I have read rave reviews and heard from friends who also didn't have results from Keto and other diets that Leptitox helped them immensely. They have a pretty convincing brief on their site. Wanted to ask if anyone has had experience as I'm very cautious trying new things. Thanks in advance!
