DL-Phenylalanine Powder

I purchased dL phenylalanine from other places and never felt a thing from them so I didn’t know why it was as popular as it is. And since Liftmode has such good products I decided to try it again. I’m so glad I did ! I actually could it lift my mood and after 2 days of taking it I noticed pain relief in my back and neck!! I will purchase this again and again!!
