L-TRYPTOPHAN POWDER
Excellent product zt quality
I take 500mg in the evening and it allows me to fall asleep faster and longer throughout the night. During the day I remain calm and serene. Works quickly after the first dose. The neutral flavor has a very small taste that is not unpleasant. Very good quality product and dissolves well in water. I am very satisfied with the product and its very good quality. HSN is really at the top. Nice day to all
