At first, I was extremely skeptical. A super supplement to improve your daily life?! But actually it works. Before I took it I reached out to them on instagram, not really expecting a response back but they did respond and quite fast. They answer all your questions and are very attentive to your needs and concerns. After not talking to them for a week they actually reached out to me asking how the suppliment has been treating me and if everything is good. That customer service goes a VERY long way in my book. I’ve not had any bad reactions at all. My mood and focus has been better throughout the day. Of course I dosent prevent having bad days but it really did improve my mood and it even helped me push afew more pounds in the gym. It definitely improved my overall workout. Yes it’s very cheap as well. Great stuff! recommended!!
