USP Labs Jack3d Review
This week I'll be reviewing USP Labs pre-workout powder Jack3d. This is a hot item
and many stores can't even keep it on their shelves. People really seem
to like USP Labs products and there has been much talk about them around the
"water cooler". All this talk got me curious so I gave a tub of
it the old college try. Jack3d is marketed as a
concentrated pre-workout formula. The serving size is much smaller than
most pre-workouts mainly because USP simplified its formula down to the few
core components. This isn't a pre-workout powder with a million (usually
ineffective) ingredients. Jack3d contains a 4.1 gram
proprietary blend of arginine AKG, creatine monohydrate, beta alanine,
caffeine, geranium extract, and shizandrol A. I'm sure that you know
arginine is good for pumps, creatine is good for size and strength and beta
alanine is good for muscular endurance but what I'd like to get into here is
the more exotic type ingredients. Geranium extract is a central nervous
system stimulant like caffeine only geranium extract has more of an amphetimine-like
effect and can really intensify workouts. The stimulant effect is further
maximized by combining the geranium extract with caffeine. USP Labs also
adds an all but unknown ingredient called shizandrol A. To put the science
in laymans terms, shizandrol A helps to lower inhibition and increases dopamine
and epinephrine in the brain. Think more energy and extra confidence when
getting under that 315lb barbell. Alot of weightlifting is psychological
and to progress sometimes we must break through mental barriers; shizandrol A
can help with that. In conclusion I would say that USP Labs Jack3d is a pre-workout
powder heavily dosed with stimulants that will jack up workout intensity.
People that like that "caffeine buzz" before a workout will like this
stuff. As far as muscle building goes, Jack3d wouldn't necessarily be my
first choice due to the low dosing of the creatine, arginine and beta
alanine. If you are looking for a pre-workout powder with a bit more
muscle building potential I would suggest BioRhythm's Juice or SSL's
