Excuse me?
PowerFULL is made of two components: PureSAP an extract of the cholorophytum plant, used for its ability to mimic Testosterone - primarily, a triterpene saponin "Stigmasterol" whose chemical structure is nearly identical to Testosterone. And PureDOPA an extract of Mucuna Pruriens, which has shown independent ability to increase endogenous Testosterone, as well as increase endogenous GHRH/GH, via levodopa.
Now, you asked which would be a better dosage, Pre-WO (which would maximize Chlorophytum's Test-mimicking effect, and reap Dopaminergic benefits) or Pre-Bed (which would induce the GH release sought after by purchasing Mucuna); the differing dosages would deliver mutually exclusive effects. So, I told you that would depend primarily on your goals. I.e., do you want the product for awareness, motor awareness (mind-to-muscle connection), and endurance (Pre-WO), or for rest and rejuvenation (Pre-Bed).
