Ordered 400 grams of dl-phenylalanine from these guys. First off the price was competitive, seeing as I could purchase this as a powder rather than in the capsule form I usually find. Secondly, it tastes just like all other dlpa that I've bought before, and I feel confident about the purity.
Just some background, I bought DLPA to increase the endogenous concentration of my own endorphins, as well as to support dopamine and norepinephrine levels. I'm feeling energized and pain free, so I believe this product is working well. I think the trick is to take a large dose of it, and since I bought in bulk for a good price I don't feel guilty about spending too much money per megadose. Thanks liftmode.com
