L-Tryptophan 50 g

Purchased at iHerb

I wasn't paying enough attention when I ordered this product. Previously I've ordered from you, and used Doctor's Best L-Tryptophan Powder USP Pharmacetical Grade 100 grams. The price was similar, and I use a similar amount each night. Therefore, I am paying about twice as much for the new to me product. I hope that in the future you will again offer the 100-gram product.
