Do they put a sprinkling of tryptophan in the cheap one and then fill the rest of it with manure or what? What exactly is the difference between pharmaceutical grade and non-phar. grade? The cheap one looks more fit for Trigger, lol.I don't know how this didn't catch my attention before, but the lesser quality of tryptophan is only about 7% tryptophan by weight (2 grams of every 28). I'm going to assume that the product is a hydrolyzed protein product, with the remainder made up of various other aminos.
In any case, I'd have no qualms about using either product. There are stricter standards applied to animal care products, in many cases, that are applied to those for human use.
