Excellent. Gave me tons of energy. Felt like I was 18 again! I'm 38 BTW and suffer from Dementia, this also helped my brain work better. Really could tell in my memory recall, and capacity to process information quickly. It's like I got upgraded to a SSD drive...lol

I have been using l-tyrosine in capsule form for a while and always ran out quickly due to local availability being hard to find and also expensive per number of capsules in the bottle with limited brand selection. I have used Nootropics Depot before and decided to get l-tyrosine in bulk this time. The only thing that would be nice is to have a scooper that would measure out the dose rather than having to rely on a mg type scale to weigh out a dose in another scooper to find the right one to use consistently. Thanks for the great product!!

Been taking this for about six weeks. Energy is more consistent and I feel less sluggish in the afternoons. Happy with the purchase.

Third-party tested, clean label. That's what I look for first. Actually works too, which is a bonus.

Switched from a more expensive brand and honestly can't tell the difference in results. Saves money.

My doctor suggested supplementing and it's been going well. Last checkup numbers looked better than before.
