6g Citrulline, 5g Betaine, patented multi-pathway pump support
Chemix King of Pumps is a no-stims pump pre-workout that's all about making your lifts feel bigger, fuller, and more effective. It combines solid nitric oxide boosts with serious cell hydration and vein support. This isn't just tossing in some citrulline. It attacks from multiple angles: ramps up nitric oxide, keeps veins relaxed, tweaks fluid balance inside and out, and delivers that muscle fullness and pressure you chase in tough sessions.
The main player is 6g L-Citrulline, right in the sweet spot of 6-8g from studies. Citrulline works better than straight arginine since it skips heavy breakdown in the gut and turns into arginine in your kidneys, feeding the enzyme that makes nitric oxide. You get better blood vessel widening, more flow to your muscles, and often a thicker, longer pump. It also helps clear out ammonia buildup from hard training via the urea cycle.
Then there's 5g betaine anhydrous, one of the biggest doses out there. Studies often use 2.5g a day, so this doubles it. Betaine acts as an osmolyte, meaning it helps cells hang onto water during workout stress, while supporting processes tied to performance. In the gym, that means better endurance, more reps, and muscles that look and feel more pumped, especially with glycerol in the mix.
Hydration comes from 3g GlycerPump™, a branded glycerol powder at 65%. Glycerol pulls in extra water and helps you stay super hydrated if you're drinking enough, making muscles feel fuller, contractions stronger, and pumps that stick around longer instead of fading quick. GlycerPump™
Chemix King of Pumps by Chemix contains 6g L-Citrulline, a clinical dose for muscle recovery and growth.
Key Highlights
- 6,000mg L-Citrulline — a real full dose, not just for show. This hits the research range for boosting arginine and nitric oxide, so your pumps feel like they last the whole workout.
- 5,000mg Betaine Anhydrous — twice the usual 2.5g from studies. It helps muscle cells keep water during tough sets, giving you fuller muscles, better stamina, and that dense feel in the gym.
- 3,000mg GlycerPump™ — a solid dose of branded glycerol for hyperhydration. It boosts fluid retention and cell swelling, creating that round, intense pump that basic formulas skip.
- 800mg Endo-pump™ — at the full suggested dose for vein support. Not a ton of public studies on the blend, but it's aimed at ramping up eNOS activity and blood vessel response.
- 254mg VasoDrive-AP® — a patented ingredient from casein that works differently than citrulline. Its VPP and IPP peptides act like natural ACE inhibitors, helping veins relax and stay flexible for smoother, deeper blood flow.
- 100mg S7™ — double the 50mg from maker's NO studies. It supports your body's own nitric oxide production and fights off breakdown from oxidation.
- 250mg Gymnema Sylvestre at 75% gymnemic acids — a smart add that's not super common. It can help with sugar handling and getting nutrients to muscles, especially if you're eating carbs before lifting.
- Stim-free on purpose — get the workout boost without caffeine downsides. Perfect for late lifts, adding your own stims, or skipping the sleep wreck from regular pres.

Who Is This For?
- Bodybuilders chasing size who rate pres by contraction feel, vein show, and muscle swell set after set. 6g citrulline, 3g GlycerPump™, 5g betaine make high-rep days connect without stim mess.
- Night owls lifting post-work who want real pre boost without killing sleep. Stim-free means better flow, hydration, and sessions without staying up wired.
- Folks who get jittery or sick from stims but need workout help. Swaps caffeine for flow and hydration that feels steady and easy to repeat.
- Stackers with their own caffeine fave. This is your pump base, add energy at your dose instead of fixed high-stims.
- Strength folks in volume phases needing long-haul support, not quick buzz. Betaine and glycerol help hydration and reps, citrulline and VasoDrive-AP® keep flow going deep.
- Cutters dropping fat who want lifts to still feel pumped and strong on low cals. This keeps your look and feel dialed with flow and cell water.
How to Use
Mix 1 scoop in 16-24oz cold water, down it 20-30 minutes before. Go high on water for GlycerPump™ and betaine—they thrive on it. New to pumps or glycerol-sensitive? Half-scoop first to check gut feel, then full. Empty stomach speeds it up, but light meal 60-90 out is cool too if that's your vibe. Skip right after big eats—digestion can lag the pump. Stim-free so stack with caffeine, salts, creatine, or intra carbs as needed. No tolerance build, no cycling. Keep it sealed cool and dry—glycerol can clump if wet.
What to Expect
Minutes 0-10: sip it down, no stims so it's chill, not a blast. Minutes 10-20: early fullness creeps in, especially with good water. Minutes 20-40: as you rep out, citrulline, VasoDrive-AP®, and S7™ bring veins, easy pumps, and better muscle pop. Minutes 40-90: hydration stack shines, GlycerPump™ and betaine keep it full and strong late instead of dropping off. Days 1-7: you feel the pump and swell right away. Weeks 2-4: stick with it and hydration, workouts get consistent, with more reps and reliable pumps from the betaine focus.

Frequently Asked Questions
How much caffeine is in Chemix King of Pumps?
None. King of Pumps is a stim-free formula, so there is no caffeine, no yohimbine, and no stimulant blend. Its effects come from 6g L-citrulline, 3g GlycerPump™, 5g betaine, VasoDrive-AP®, S7™, and other pump-support ingredients.
Is 6g of L-citrulline enough to actually feel a difference?
Yes. 6g is the lower end of the clinically supported 6-8g range used for nitric oxide and blood-flow support, and it is meaningfully stronger than the 3-4g doses commonly seen in underdosed pump products.
What makes King of Pumps different from a basic citrulline-only pump formula?
It attacks the pump from multiple angles instead of just one. Citrulline supports nitric oxide production, VasoDrive-AP® supports vasodilation through ACE inhibition, S7™ helps preserve nitric oxide bioavailability, and GlycerPump™ plus 5g betaine build the hydration pressure that makes the pump feel dramatic.
Why is VasoDrive-AP® included at 254mg?
254mg is a meaningful entry point for this patented casein hydrolysate and sits within the commonly referenced 254-508mg use range. It provides the lactotripeptides VPP and IPP, which support blood vessel relaxation through ACE inhibition rather than the arginine-NO pathway alone.
Can I stack King of Pumps with a caffeinated pre-workout?
Yes, and many experienced users do exactly that. Because King of Pumps is stim-free, it can serve as the blood-flow and hydration base while a separate caffeine product provides energy; just pay attention to total ingredient overlap and overall stimulant intake.
Do I need to take King of Pumps every day?
You do not need daily use for the acute pump effect, because citrulline, glycerol, and VasoDrive-AP® are primarily felt around the workout itself. That said, consistent use can help you build more repeatable hydration and performance habits, especially with the high-dose betaine component.
Will this help if I train at night?
Yes, that’s one of its best use cases. Because there are no stimulants, it can improve pump and session quality without making it harder to fall asleep afterward.
Is Gymnema Sylvestre just filler in this formula?
Not exactly, but it is not the main reason to buy the product either. Gymnema at 250mg standardized to 75% gymnemic acids is better viewed as a metabolic support ingredient that may complement carbohydrate handling around training rather than a primary pump driver.
Does GlycerPump™ cause clumping in the tub?
It can over time, and that is common with glycerol-containing formulas. Clumping does not mean the product is bad; keep the lid tightly closed, store it in a cool dry place, and avoid moisture exposure.
Is this formula fully transparent?
It is transparent where it matters most, with disclosed doses for the major active ingredients like citrulline, betaine, GlycerPump™, VasoDrive-AP®, Gymnema, and S7™. Endo-pump™ is a trademarked matrix at 800mg, so you know the total dose but not the exact breakdown of each component inside that blend.
