I've been taking ACTIVE PK every morning for exactly 30 days now. I don't have any side effects and zero jitters but increased energy. I'm not dropping weight at a crazy pace but definitely feeling smaller. I'm actually glad that this is not a drastic, "miracle" weight loss pill. I think those products are gimmicks that are not sustainable. This is more of just a health supplement. Those "quick fixes" are not what I was after so I'm happy with the product this far. I generally just feel healthier. I'll definitely keep using it ACTIVE PK!
