PowerFULL has two parts to it:
PureDopa - an extract of Mucuna Pruriens standardized for 50% L-Dopa
PureSap - an extract of triterprene saponins, primarily Stigamsterol, from Chlorophytum
The former of the two constituents is affected by carbohydrate metabolism, while the latter is not. A pre-workout dose of PowerFULL can contribute to anabolism vis-a-vis positive nitrogen balance, glycogen retention, and increased protein synthesis.
Stigmasterol is very chemically similar to Testosterone, but lacks androgenic capability. Essentially, this means it's a mimetic in the sense it will induce increased protein transcription, but it will not bind to the AR and cause shutdown.
A pre-workout dose of PowerFULL + creatine monohydrate + caffeine is a pretty intense workout.
