T.J. Clark L-tyrosine Liquid Formula, 500 Mg, 8 Fl Oz (1 Bottle)

This is a great product and I recommend anyone buying it. It was delivered in a timely manner and I had no problems with the company, at all. A 5 star product!

I consider this product defective because I and TWO OTHER PEOPLE, including one a physicist at a national laboratory and, assumedly, not stupid, couldn't open the bottle. My attempt to contact the seller, TWICE, went unanswered, including my request to return it. Can't recommend this seller.

Tasty liquid to improve focus and concentration

I was excited to try this product, when I received It, I smelled it and it smelled sweet and I was like hmm .....I read the ingredients and saw it has vanilla flavoring me personally I love vanilla but I want the actual product to be pure since I desperately wanted it to work. Unfortunately, as suspected after I smelled the vanilla I finished the product and absolutely made i had no changes in my cognitive behavior.....drinking it taste like I was drinking sugary water, and I was loosing so much of the product with the cap mechanism everytime I would shake it and open it so much of the product would start dripping out and there was no way to save it. It's a no for me.

It's perfect. Exactly as advertised. Arrived I tip top shape.

Love, love the product. The bottle is difficult. It spills very easy when trying to pour into spoon. The opening is too small to place spoon into. The lid is not tight after opening so it leaks when you shake it. It must be shaked as you can see that it does separate a bit. Does not wipe off clothes with a towel or sponge when spilled or shakes out onto your clothes, looks like chalk on your shirt. It does wash out in the laundry. I found using a little measuring spoon works because you can place it into the opening and dip out product. The product absorbs into my body quickly. Much faster than taking capsules. I will continue to buy but hope for a new design of the bottle.

I purchased this product to manage my hypothyroidism. I give it five stars for a change in my symptoms. However, I would like to reserve the rights to amend this comment after a later time when I can substantiate the difference in further detail.

So far I like it fine. I will try another bottle of it after I use the powder form of the same product.
