Very good
Before I used to take L-tyrosine and did not notice anything and when I started taking this acetylated form I noticed more energy and concentration.

Valuable
It is one of the supplements that I have the highest esteem for the activation it gives me in the morning, to go to train without breaking my fast and also help to reestablish my circadian rhythm.

N-ACETYL L-TYROSINE POWDER
Excellent, but not the same packaging as the image.
Everything perfect, very fast shipping and in excellent condition. Only thing that caught my attention was not receiving the same packaging of the image, this is a white packaging instead of gray so I thought there was an error in the shipment, fortunately not. The closure works perfectly. The taste is a pleasant acid, I dissolve it in green tea or in little water since the daily dose is very small. I started 3 days ago so I can't really evaluate the effectiveness. The price I got it at almost 10 euros in promotion so I took advantage of 2 packs to maintain consumption over time, it would be excellent that this is the standard price! We will see its effect!

N-ACETYL L-TYROSINE POWDER
Less efficient than regular tyrosyna
Studies support that L-tyrosine supplementation is superior to NAT. Oral L-tyrosine supplementation increases plasma tyrosine levels by 130-276%, whereas intravenous NAT provides only a 0-25% increase. Due to the inefficient conversion of NAT to tyrosine, up to 60% of NAT is excreted in the urine unchanged, meaning that it was never converted to tyrosine. Although NAT is more soluble than L-tyrosine, it is an inferior form of tyrosine supplementation. So why do companies use N-acetyl tyrosine instead of L-tyrosine? Because it dissolves better in water and they have not adequately researched the subject.

Noticeable from the first use
You can feel the boost in mood. I think it is important to space out the intakes to avoid possible tolerance or dependence.

Great
First time I buy it individually (I had already taken it in a pre-workout product) and I am very happy taking it with my coffee before training.
Info
The crossed-out price or the one shown as "PVPR" on our website is not a value arbitrarily estimated by HSN. This amount strictly corresponds to the official list price recommended by the manufacturer (or by our product development department in the case of own brands) for individual sale in the general retail market.
This information is used solely as an informative reference to allow the consumer to compare our current price with the standard market price suggested for a product of that category and quality.
Why is our price much lower? The large difference you perceive is not because the PVPR is inflated, but due to our business model. At HSN we operate under a Fair Price policy based on our business model with the elimination of intermediaries (Direct-to-Consumer Model).
The PVPR reflects the cost the product would have if it went through the traditional distribution chain (Importer > Wholesaler > Physical Store).
By purchasing on our website you acquire the product while avoiding those added costs. Therefore, the "discount" shows the structural savings we offer versus the industry's standard recommendation.
