Review: Absolutely amazing - There is a lot of products out there that really make it hard to find the right one. Let me just tell you guys that as a physician I really have to do my own research to make sure that what people sell is NOT snake oil. This product really works well, it has enough ingredients to replace about 4 to 5 different bottles and I really think the best way to use this product is with the expectation that you will see subtle changes that occur with time. No side effects for me. I really think this hits all of my requirements, and that it is natural, safe, and effective without any crashes for me. In short, my focus specially in long day shifts has improved and I’ve seen some really nice and gradual changes in my mood. I am more well-rounded in terms of my thinking, and as a physician this really is a big step forward in a natural way to help with focus instead of using Prescription medication. I would highly recommend this to anyone. Try it and see for yourself.
Review: The best - Unbelievable. Here is the translation in English: This one, despite having few compliments, should be one of the few to be the best I’ve ever tested in my life, the best overall, with an action time of less than 1 hour, no side effects. I tested Qualia, $180 wasted with no results. This means that the price of the product doesn’t indicate anything about its quality. This product made me wake up, it awakened my senses, made me remember things from 20 years ago as if they were yesterday. Well, this is one of the points. After that, if this product doesn’t solve your problem, see a doctor. This product is not a miracle.

### ⭐⭐⭐⭐⭐ Became my go to for focus!
*by A***H on May 2, 2023*

If I had to describe the feeling of taking this in two words it would be "calm focus". I wouldn't consider myself a supplement junkie but I've tried a good amount of supplements over the past 5-6 years since I got off my ADHD prescription and CRTX is at the top of the list for me when it comes to focus. I love how I feel when taking it and had zero side effects and for someone with an iffy stomach that's a huge plus. The serving size is perfect, I've done a fair bit of research and the serving size lines up with most clinical trials that have been done on the supplements. If you're looking for a calm focus boost and are looking for something without caffeine, look no further!
