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.

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!
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!

Works well
Works very well for me with my regular meds. Alone however I can still lose some focus when bored. My adhd is inattentive...very inattentive lol. I also suffer narcolepsy so that may play into this. But I do like this product. Came thru ina pinch when my pharmacy ran out of my typical meds😑. The price is a bit steep for me vs my regular as well. Doesnt look like the pic either, but dont let that steer u away. My pills are brown not white.

No Discernible Benefits
I’ve been trying lots of different nootropics lately. I normally give them about 6 weeks to get a good feel for them. I’m changing to something else 4 weeks into these because they just don’t work as advertised. Wish I could get the money back for the last bottle, but oh, well. 0/10. Would not recommend.

Great & Stackable
My first day I used this with no caffeine. It wasn’t a bad experience at all. I typically need some sort of caffeine when I get off of work, but I didn’t need it. I had taken it 4 hours previously by the way. My second day using this I paired it with caffeine. This was an amazing experience. I was energized physically and mentally. As a middle school teacher, this is everything that I need. It’s a stacked formula. It doesn’t feel overwhelming. With or without caffeine this is a great product. It gives a smooth, focused mental state. I’ll be using this for teaching, preaching, and lifting. I highly recommend a purchase!

Smooth, clean focus
Gonna keep it as short and sweet as possible 3 caps with no caffeine: good, some days I didn't need any caffeine to focus or work which is incredible as I usually intake 2-4 cups of coffee a day. 3 caps with caffeine: great, kept the jitters and the urge to jump from task to task, or to stop in the middle of boring tasks at bay. 6 caps with no/low caffeine: incredible! Plowed through tasks, worked quickly, felt like time was moving more slowly with how quickly things were getting accomplished. 6 caps with high caffeine: Amazing! Whether it was going into the office or going to the gym, taking this with 2-400 caffeine felt illegal it was so good!

Strong & Effective
CRTX is about as solid as it gets when it comes to an effective pill-based nootropic. The large theanine dose is not my favorite and can be a bit worrisome when it comes to losing its punch, but there's plenty of brain activation going on to counteract that for the most part. For people who are trying to cut down on stimulants and make them work a bit better, this is perfect for you adding with your morning coffee or afternoon energy drinks. While the price point is pretty steep and that's a big downside, many people will be able to get away with the 30 serving dose and still be impressed. Seems like a legit company and looking forward to what else they put out.
