PUMPDROL®
The pump that outlasts the session. Where arginine gives you 30–60 minutes, PUMPDROL® runs nitric oxide through two pathways at once — L-citrulline for the enzyme route and arginine nitrate plus beetroot for the nitrate–nitrite–NO route that recycles for hours — with HydroMax® glycerol pulling water into the muscle to fill what the blood flow opens. Caffeine-free, so it stacks with any pre-workout or stands alone in the evening.

Three ways to chase a pump. Only one keeps it after the caffeine wears off.
Here's how PUMPDROL® measures against the two products lifters usually buy for a pump — an arginine-based nitric-oxide booster, or a caffeinated pre-workout with a pump ingredient tacked on.
- Poor oral bioavailability
- Gut upset at effective doses
- Pump gone before the last set
- Pre-workout or sipped intra-workout
- Evening sessions and caffeine-sensitive lifters
- Verified, HPLC & FTIR tested
- Vasoconstriction from caffeine blunts the pump
- Useless after 4 pm
- Tolerance builds; cycling required
| What decides the pump | Arginine booster | PUMPDROL® | Caffeinated pre-workout |
|---|---|---|---|
| Enzyme (NOS) pathway | L-arginine, poorly absorbed | L-citrulline — raises blood arginine more than arginine itself | Sometimes citrulline |
| Nitrate → nitrite → NO pathway | — | Arginine nitrate + beetroot powder; recycles for hours | Rarely |
| Cell volume | — | HydroMax® glycerol | Rarely |
| NO protection | — | Pomegranate, grape seed, curcumin | — |
| Peripheral flow & focus | — | Cnidium, centella, bacopa, hawthorn, black pepper, yohimbe | Caffeine |
| Stimulants | None | None (contains yohimbe) | High caffeine |
| Form · dose | Capsules or powder | Flavoured powder · 1–2 scoops pre-workout or sipped intra · max 2/day | Powder |
| Verification | Rarely | Scratch-and-verify · HPLC & FTIR tested | Rarely |
One scoop. Seven angles of attack.
Click any point on the chart to see which ingredients handle that job — and the one-line mechanism behind each.
Every ingredient. One line each.
Fourteen actives in a 5,000 mg formula, listed in label order. Red bars mark the nitric-oxide and volume drivers; navy marks flow, focus and antioxidant support.
L-Citrulline
Bypasses the gut and liver, converts to arginine in the kidneys, and raises blood arginine — and nitric oxide — more reliably than arginine itself; also clears ammonia.
Arginine nitrate
Arginine bonded to nitrate: the nitrate converts to nitrite and then nitric oxide independent of the enzyme, and recycles back for hours of dilation.
HydroMax® glycerol
Hyper-hydrates muscle by holding water inside the cell, so the vessels the nitric oxide opens have volume to fill.
Pomegranate (Punica granatum)
Punicalagins protect nitric oxide from free-radical destruction and supply natural nitrates of their own.
Grape seed extract
Proanthocyanidins raise antioxidant enzyme activity and support endothelial nitric-oxide release.
Cnidium monnieri
Osthole relaxes vascular smooth muscle and supports nitric-oxide signalling.
Centella asiatica (gotu kola)
Triterpenes strengthen capillaries and improve peripheral blood flow — the small vessels the pump shows up in.
Bacopa monnieri
Bacosides support cerebral blood flow and focus without stimulation.
Crataegus (hawthorn)
Procyanidins support cardiac output and healthy blood pressure while vessels are dilated.
Piper nigrum (black pepper)
Piperine improves uptake of the botanicals in the formula.
Stellaria media (chickweed)
Traditional vascular tonic with saponins and flavonoids that support vessel health.
Curcuma longa (turmeric)
Curcuminoids reduce oxidative stress in the endothelium so nitric oxide keeps working.
Yohimbe bark extract
Alpha-2 antagonist that increases peripheral blood flow and lipolysis; the reason this formula carries a caution.
Beetroot powder
The best-studied dietary nitrate source, feeding the nitrate–nitrite–NO cycle alongside arginine nitrate.

Reading the label
- Two nitric-oxide routes, not one. Citrulline feeds the enzyme; arginine nitrate and beetroot feed the nitrate cycle. That's the reason the pump lasts beyond the session.
- Glycerol is the volume. Dilation alone gives vascularity; HydroMax® glycerol gives fullness. Drink the full 240–350 ml — glycerol needs water to work.
- Antioxidants are load-bearing. Nitric oxide is destroyed by free radicals within seconds; pomegranate, grape seed and curcumin are there to protect it, not for decoration.
- Caffeine-free, not stimulant-neutral. There's no caffeine, so it stacks with a pre-workout or works in the evening — but yohimbe bark is in the formula, so start at one scoop.
- "Sip it during training" is a label direction: half pre-workout, half in the shaker across the session extends the nitrate delivery.
- Nitrates and medication don't mix. Anyone on nitrate heart medication, blood-pressure drugs or ED tablets should not use it without medical advice.
From scoop to the pump that walks out with you.
Citrulline enters the kidneys' arginine cycle; nitrate from arginine nitrate and beetroot is taken up and begins reducing to nitrite. Glycerol starts drawing water into muscle.
Both nitric-oxide routes run at once: enzyme-made NO from citrulline and nitrite-derived NO in the working muscle, where oxygen is low. Vessels widen; the pump fills.
Spent nitric oxide oxidises back to nitrite and nitrate and is re-reduced; pomegranate and grape seed slow the free-radical destruction. Vascularity outlasts the session.
The nitrate pool depletes gradually rather than crashing. No stimulant comedown, no sleep disruption — which is why evening trainers can use it.
Eight reasons PUMPDROL® is the pump product of record.
Two nitric-oxide pathways
Citrulline for the enzyme, nitrates for the nitrite cycle. Most pump products use one; PUMPDROL® runs both.
A pump that lasts hours, not minutes
Nitrate recycling keeps nitric oxide available long after arginine-based products have faded.
Fullness, not just veins
HydroMax® glycerol hyper-hydrates the muscle so the dilation shows as size, not only vascularity.
Caffeine-free
Stack it with any pre-workout, use it for evening sessions, or run it on stim-free days — no tolerance build-up, no cycling needed.
Nitric oxide that survives
Pomegranate, grape seed and curcumin protect NO from the free radicals that would otherwise destroy it in seconds.
Sip it through the session
The label allows intra-workout sipping, so nitrate delivery can be spread across a long or high-volume session.

Nitric oxide is now a health conversation, not just a gym one.
Nitrates go mainstream
Beetroot and dietary nitrate moved from endurance-lab curiosity to blood-pressure and performance staple.
Fit: arginine nitrate + beetroot in every scoop.
The stim-free shift
Lifters are separating "energy" from "pump" and buying caffeine-free formulas they can use any time.
Fit: zero caffeine; stacks with any pre-workout.
Citrulline replaced arginine
The research settled it: citrulline raises blood arginine more effectively than arginine does.
Fit: citrulline leads the label.
Endothelial health as longevity
Nitric-oxide capacity declines with age and is tracked as a vascular-ageing marker.
Fit: NO production plus antioxidant protection.
Hydration inside the cell
Glycerol hyper-hydration crossed over from endurance sport to physique training.
Fit: HydroMax® glycerol.
Intra-workout sipping
Spreading pump ingredients across the session is standard practice for long or high-volume training.
Fit: the label allows it.
Every question we've been asked about PUMPDROL®.
What exactly is PUMPDROL®?
A stimulant-free pump formula: L-citrulline, arginine nitrate and beetroot for nitric oxide through two pathways, HydroMax® glycerol for cell volume, and ten botanicals for blood flow, focus and nitric-oxide protection, in a 5 g scoop taken before or during training.
How does it work?
Citrulline feeds the enzyme that makes nitric oxide; arginine nitrate and beetroot feed the nitrate–nitrite–NO route that works even where oxygen is low and recycles for hours. Glycerol fills the widened vessels with volume; pomegranate, grape seed and curcumin stop the nitric oxide being destroyed.
Why nitrates instead of arginine?
Arginine is mostly broken down in the gut and liver before it reaches the enzyme, and what survives lasts under an hour. Nitrates convert to nitric oxide by a separate route and recycle, which is why the pump outlasts the session.
Does it really last 8 hours?
The nitrate cycle keeps nitric oxide available for hours rather than minutes; how long the visible pump lasts depends on your training, hydration and body fat. Expect vascularity well after the session, fading gradually rather than crashing.
How do I take it?
One scoop in 240–350 ml water 30 minutes before training. For long or high-volume sessions, a second scoop sipped through the workout. Never exceed two scoops in 24 hours.
Can I sip it during training?
Yes — the label allows it. Half a scoop pre-workout and the rest in your shaker across the session spreads nitrate delivery through a long workout.
Does it contain caffeine?
No. It's stimulant-free, so it works for evening sessions and stacks with any pre-workout. It does contain yohimbe bark, which some people feel — start with one scoop.
Can I stack it with a caffeinated pre-workout?
Check both labels and your total stimulant and vasodilator exposure first. Do not combine it with another yohimbe-containing product; ask a qualified healthcare professional if you are unsure about ingredients, medication or blood pressure.
Why does the pump matter?
Blood flow delivers oxygen, amino acids and glucose to working muscle and clears the waste; cell swelling is itself a growth signal. The pump is a training tool, not just a look.
Will it help for a photo shoot or show?
Yes — one scoop 45 minutes before, with a pump-up. Keep water intake normal so the glycerol has something to hold.
Why do I need to drink so much water with it?
Glycerol works by holding water inside the muscle. Without adequate fluid it can't create fullness and may cause a headache.
Can nitrates give me a headache?
Some people get a mild nitrate headache, especially dehydrated. Start with one scoop, drink the full water, and it usually resolves. Persistent headaches — stop and consult a doctor.
Will it lower my blood pressure?
Nitrates and the vascular botanicals do lower blood pressure modestly. That's fine for healthy adults; anyone on blood-pressure medication or with low blood pressure needs medical advice first.
Can I take it with ED medication or heart nitrates?
No. Combining nitrates and vasodilators with prescription PDE5 inhibitors or nitrate heart medication can drop blood pressure dangerously. Talk to your doctor.
Do I need to cycle it?
No. There's no stimulant tolerance to manage; it can be used every training day.
Rest days?
Not needed for the pump, but some users take one scoop on rest days for the vascular support. Optional.
Is it suitable for women?
Yes. It's non-hormonal; the same dose applies. Not during pregnancy or nursing.
Is it vegetarian?
Yes — amino acids, glycerol and plant extracts. No animal ingredients.
Is it banned in sport?
No prohibited stimulants. Tested athletes should check yohimbine against their federation's list and keep the batch and verification record.
Any side effects?
Uncommon at one scoop with adequate water. Possible mild headache or flushing from nitrates, or restlessness from yohimbe — reduce the dose. Stop for dizziness or palpitations.
Should teenagers use it?
No. Adults 18+ only.
Does it break a fast?
A scoop is effectively calorie-free and sugar-free; for most fasting purposes it won't break a fast.
How long does a jar last?
60 scoops: three months at one scoop on five training days a week, or six weeks at two.
Where is it made?
Manufactured in San Diego, California, at an FDA-inspected, GMP-certified facility, and marketed in India by Hybrid Laboratories (India) Private Limited.
How do I verify my jar?
Enter the code at myogenetix.in/verify before first use.
How should I store it?
Cool, dry, lid tight, scoop dry — glycerol powders attract moisture. Keep out of reach of children.
Open the vessels. Fill the muscle. Keep it for hours.
