I had a look at the veterinary grade Tryptophan at buygpdirect.com, but it seems to be only "90% Tryptophan," whereast the pharmaceutical grade trytophan available on some websites claims to be 99.9% pure Tryptophan. I'd be very nervous about taking the 90% stuff 'cause who knows what the other 10% is.
