Well with 60 capsules for the price, a 2 month supply, I decided to try it. This product has been a game-changer for me! The price for the amount you get is fantastic. I've been taking it consistently for few weeks now, and it hasn't upset my stomach at all. The product itself is tasteless, which I appreciate. The size of pill doesn't make hard to swallow, (some might find it on bigger end). Most importantly, it's actually working! I'm finding myself much more active and less stuck in that "holding pattern" feeling. I don’t get fatigue towards end of day or any sort of "crash". I'm able to think much clearer, I have ADHD and tend to be "all over the place" but not with this. My sleep has also significantly improved, I can actually sleep through the night now. Highly recommend
