PowerFULL is sleep-aid, but not in the traditional sense. The 20 fold increase of endogenous GH following a PowerFULL dosage will assist in obtaining, and remaining in, the most fruitful state of rest - REM state. However, it will not necessarily induce that state, as it does not modulate melatonin in any direct manner. Mucuna can also have a neuro-stimulative effect in some, due both directly to the increase in dopamine, as well as independent action on neurotransmitters associated with memory, emotion, wakefulness and alertness. My favorite suggestion: dose PowerFULL literally as you are falling asleep. This will avoid any neuro-stimulative effects which may disrupt your bedtime ritual, while still helping to maintain incredibly restful REM-state sleep throughout the night!
