Pump Action Stim-Free Pump Capsules with Nitrosigine
Pump Action was built for athletes who want more out of their training without relying on heavy stimulants. Designed for lifters chasing insane pumps, improved blood flow, endurance, and focus, Pump Action is for the ones training with intensity whether it’s early mornings, late nights, or stacked alongside their favorite pre-workout.
We made this formula for people who still want to feel locked in and perform at a high level without the jitters, crash, or sleepless nights that can come with high-stim products. Whether you’re stimulant-sensitive, cycling off caffeine, or simply want to maximize your pump and performance, Pump Action delivers the support to help you push harder, train longer, and leave the gym feeling accomplished — not burnt out.
- NUTRIENT DELIVERY*
- MASSIVE PUMP*
- IMPROVED VASODILATION*
- IMPROVED RECOVERY*
- INCREASED ATHLETIC OUTPUT*
- PINK HIMALAYAN SALT 150mg Pink Himalayan Salt provides your body with essential nutrients and replenishing electrolytes that you lose through sweat.* This is important for optimal performance and muscle hydration.
- NITROSIGINE® 1.5g Nitrosigine® is a patented complex of bonded Arginine Silicate. Shown to be more effective than L-Arginine. Supports greater blood flow and vasodilation. This leads to Nitric Oxide production, increased brachial artery diameter, and improved blood arginine levels.* A 2020 randomized crossover trial measured a 31% increase in flow-mediated dilation 60 minutes after dosing, versus a 2% decrease on placebo.
- VASODRIVE AP® 508mg of VasoDrive-AP®, a lactotripeptide derived from casein and one of the most researched ingredients in the pump category. Research suggests it supports nitric oxide production and vasodilation, which is what drives blood flow to working muscle.* See a systematic review and meta-analysis of randomized controlled trials on the mechanism.
Both drivers in Pump Action carry human clinical research at the exact per-serving doses on the label.
- Nitrosigine® 1,500 mg — the same dose used in a randomized, double-blind crossover trial (Journal of the International Society of Sports Nutrition, 2020) where it improved flow-mediated dilation, a measure of blood-vessel responsiveness, in healthy active adults comparably to 8 g of citrulline malate.*
- VasoDrive-AP® 508 mg — its lactotripeptides (IPP and VPP) have been examined in a systematic review and meta-analysis of randomized controlled trials. Research suggests modest, population-dependent vascular effects; we use it for blood-flow support, and it is not a treatment for any condition.*
Straight talk: the Nitrosigine evidence base is small, roughly a dozen indexed studies. We cite what exists instead of inflating it, and both doses above match the label, not a fairy-dusted fraction of the studied amount.*

4 small pills is all it takes to take your nitric oxide and vascularity to another level. No additional flavoring, no sweetener, no extra fluff. Just capsules filled with pump.
Two patented pump ingredients at their full clinical doses: Nitrosigine® at 1,500 mg and VasoDrive-AP® at 508 mg, plus 150 mg sodium for plasma volume. Research suggests both support nitric oxide production and vasodilation.* Dynamite comes in small packages.
No caffeine, no stimulants, no B.S. Just a nasty pump in 4 simple pills. Take 20-30 minutes before training and let the muscles swell up. You will not be disappointed by this product!
Pump Action can be taken stand alone or stack it with your favorite preworkout for an insane muscle pump. Choose your weapon of destruction.

Frequently asked questions
The questions we get asked most about Pump Action. If yours is not here, reach out.
Pre-workout typically takes 20 to 45 minutes to kick in, depending on the ingredients and your metabolism.
- Pump ingredients like Nitrosigine and VasoDrive AP take 30-60 minutes to reach full effect.
For best results, take your pre-workout 30 minutes before training on an empty or lightly fed stomach.
Yes. Pump Action is completely stim-free, so there is no caffeine tolerance to build and no reason to cycle off it the way you would with a stimulant pre-workout.
Take 4 capsules 20 to 30 minutes before training, on training days. If you also run a caffeinated pre-workout, Pump Action stacks on top of it without adding any stimulant load.
Since Pump Action is a stimulant free product, there is no concern for jitters or crashing. This is a common side effect from preworkouts containing large amounts of caffeine. Pump Action was designed to remove this potential, giving you the pump benefits you expect from a preworkout without affecting your central nervous system.
To give you the pump you expect from a pre-workout without any of the other stuff. No stimulants, no tingles, nothing that touches your central nervous system or your sleep. Just 1,500 mg of Nitrosigine® and 508 mg of VasoDrive-AP® in four capsules.*
No Pump Action does not contain Beta-Alanine. This is the most common ingredient found in preworkouts that leads to the paresthesia effect (tingling sensation). With Pump Action, the goal is massive muscle pumps and improved blood flow.
If you are a person who enjoys the tingling sensation, please look to stack Pump Action with a preworkout containing Beta-Alanine.
