All the indicators suggest that i should have reaped massive benefit from this particular supplement, but i don't remember ever having taken them (Have since run out and am writing this almost a year after purchasing) maybe i'll restock to double check

Something about this ingredient seems to have a detrimental effect on my energy. I used to take it in the morning with my Stimulants, and at first it worked well but eventually I started becoming severely fatigued in the evening or late afternoon. Could just be the combination of this and my stimulants, though.

What Is D, L-Phenylalanine Capsules? Phenylalanine is an essential amino acid, which means your body can’t produce sufficient amounts and requires it from an external source. It’s converted to L-tyrosine in the liver, which is then converted into dopamine, norepinephrine and epinephrine (adrenaline) hormones that can become depleted for a variety of reasons. Replenishing norepinephrine in the brain can support brain health. The neurotransmitters produced from phenylalanine supplementation bring a wide range of cognitive health benefits. D, L-Phenylalanine Benefits Supports production of L-tyrosine, which is used to make dopamine, norepinephrine & epinephrine Helps promote healthy mood & sleep Supports healthy cognitive function Provides protection for brain cells
