I am and have been a long term user.
PURE delivers every time the high quality.
I have tried many other Brands of L-Tyrosine and there is NO OTHER BRAND/Company out there that has the high quality Pure consistently delivers.
But I have to say I did it without doctor or dietician advice and my TSH (free T4 reflex) blood test looks like I have hyperthyroidism!
Check with doctor or dietician! Don’t just buy and use without knowing what you are doing to your system. It’s not a free ride, even if you have healthy kidneys.

I read where L-tyrosine and turmeric are good for brain injuries (I think I had an untreated concussion from a car accident years ago). I could be wrong, but I have tried numerous products trying to get me to just be "normal".
I was always weary, unmotivated, poor memory and focus, and just existing. Since starting to take this product and turmeric, I would say I am about at 80%. I still have a ways to go, but feel this regimen is a huge step in the right direction. (I'm hoping if I get more serious about my eating and exercise habits, that will be the final piece of the puzzle to be back at 100%).
About 30 minutes after taking the capsule, I felt a little nauseated, dizzy, and hot. That lasted about 20 minutes. I felt normal for the rest of the day.
I don't know yet if this supplement deserves the credit, but I was more productive than usual today. I was more motivated and focused. My mood was better as well. Not huge changes, but I felt better today than I have in months.
I'm reluctantly giving the product five stars because Pure Encapsulations was recently purchased by Nestle which ... doesn't have the same great reputation as Pure Encapsulations so hopefully, the corporate culture and dedication to a truly great product (not just great advertising) of Pure Encapsulations affect Nestle more than the other way around.... time will tell.
