Constrictor Pre-Workout

The Pump is the stuff of legend. Ever since Arnold discussed the phenomenon in Pumping Iron, the pump has been the driving force behind many a workout. Lifters train relentlessly all in the hopes of capturing the ultimate muscle pump, the kind where your sleeves are busting and veins are bursting through your skin. The pump is an elusive beast, one the eludes even the most hardcore lifters out there…but not anymore.

Constrictor from RUI-Labs is the ultimate muscle-swelling, vein-gorging, and sleeve-busting pre-workout on the market. Vascular is stimulant free and provides a robust combination of nitric oxide boosting ingredients to generate a raging pump that lasts all day long. RUI-Labs has also included a hefty dose of nootropics to combat mental fatigue and enhance focus in the midst of your battle against the iron.

Pumps, Focus, Endurance — Constrictor delivers it all!

Sodium Nitrate (1.5g) creates a powerful surge in nitric oxide production. Nitrates are 100% bioavailable and can increase plasma NO levels by 138%, delivering significant vascularity and “blood flow” to working muscles leading to a massive muscle pump.

Alpha GPC (250mg) fosters a strong mind-muscle connection by increasing levels of the neurotransmitter acetylcholine, a.k.a. ?the learning neurotransmitter.? WIth Alpha GPC, you?ll feel every muscle fiber becoming engorged as you grind out rep after rep.

Huperzine A (300mcg) supports acetylcholine production in the body by inhibiting acetylcholinesterase, the enzyme that degrades acetylcholine. The 1-2 punch of Huperzine and Alpha GPC promote incredibly strong, long-lasting focus that delivers tunnel vision like you?ve never experienced before.
