This isn't a magic weight loss pill but it does work. I've been taking it while making changes to my diet. With cutting out a lot of the bad I use to eat and drink (sweets and sodas) I saw more fat loss than I did before taking RSP. I haven't been able to hit the gym as hard as I use to because of shoulder and elbow injuries but I still saw results doing the little exercise I could. I haven't had any side effects from this and will keep taking it because I think it really does help. You still have to watch what you eat and drink and do SOME exercise but I believe adding this supplement really helps. I'm down about 20 pounds and have another 20 to go and I know this is going to get me there.
