Description
InnovaPharm Poppa Pump
A stimulant-free pump product in capsule form: 1.5g of Nitrosigine, 500mg red radish extract, 400mg Korean red ginseng and 255mg VasoDrive-AP, in a five-capsule serving.
No powder, no shaker, no mixing. That is the practical appeal — and the Nitrosigine behind it solves a problem that held nitric oxide supplements back for years.
The arginine paradox — and how Nitrosigine gets around it
This is the most satisfying explanation in the pump category, and it explains why nearly every product now uses citrulline instead of arginine.
Arginine is the direct precursor to nitric oxide. Nitric oxide synthase takes arginine and produces NO from it. So logically, supplementing arginine should be the most effective route.
It is not, for two reasons that together are known as the arginine paradox:
- Poor oral bioavailability. Swallowed arginine is largely broken down in the gut and liver — the first-pass effect — before it reaches circulation
- The doses large enough to overcome that cause stomach upset. So you cannot simply take more
That is the paradox: the ingredient that should work best is the one you cannot practically take enough of. It is why the industry moved to citrulline, which survives digestion and converts to arginine in the kidneys — raising arginine levels more effectively than arginine itself.
Nitrosigine takes the other route. Nutrition21 buffered the arginine molecule with inositol and potassium silicate, which protects it from that first-pass breakdown. The result is inositol-stabilised arginine silicate — arginine that actually arrives.
Poppa Pump uses 1,500mg, the clinically studied dose. In research on Nitrosigine, upper leg circumference was measurably increased after three days of use — which is unusual, because it is a physical measurement of a pump rather than a subjective report.
⚠ Skip antibacterial mouthwash on training days
The 500mg of red radish extract is a nitrate source — radishes are among the more nitrate-rich vegetables — and that means this applies.
The first step of the nitrate pathway is performed by bacteria on the back of your tongue, which convert nitrate to nitrite. Your own cells do not do this. Antibacterial mouthwash kills those bacteria, and studies on dietary nitrate show it substantially blunts the effect.
Same caveat as our NovaPump, GHOST Pump and Opti-Reds pages. It is the easiest way to waste an ingredient you have paid for.
Note the mechanism here is genuinely separate from the Nitrosigine. Nitrosigine supplies arginine as substrate; nitrate produces nitric oxide by a route that bypasses the enzyme entirely. Two pathways, not two versions of one.
⚠ It contains dairy — which nobody expects in a capsule
VasoDrive-AP is made from hydrolysed casein tripeptides — specifically the lactotripeptides IPP and VPP, derived from milk protein.
They are studied as natural ACE inhibitors: rather than pushing vasodilation harder, they interfere with the enzyme pathway that constricts blood vessels. That is a genuinely different mechanism from everything else here, and a clever inclusion.
But it makes this a milk-derived product. If you have a dairy allergy, that matters — and a pump capsule is the last place most people would think to check. It is also why "suitable for vegetarians" does not mean suitable for vegans.
An honest note on HEMO-Growth
The formula includes 200mcg of HEMO-Growth, described as fibroblast growth factors and activin.
Growth factors are proteins. Proteins taken orally are digested into amino acids in the stomach and small intestine — that is what digestion does. Whether an orally administered growth factor survives to act as one is a substantial question, and 200 micrograms is a very small amount.
This is an obscure ingredient with very little published research behind it. We are not saying it does nothing; we are saying the evidence is not there to say it does something — and you should not buy this product for that ingredient. The same note appears on our Heavy Duty page, which also contains it.
Buy Poppa Pump for the Nitrosigine. That is the ingredient with real dosing and real research behind it.
Specs (5 capsules)
| Nitrosigine | 1,500mg (clinically studied dose) |
| Red Radish Extract | 500mg |
| Pink Himalayan Salt | 500mg |
| Korean Red Panax Ginseng | 400mg at 70% ginsenosides |
| VasoDrive-AP | 255mg (casein-derived) |
| HEMO-Growth | 200mcg |
| Sodium / Potassium | 200mg / 60mg |
| Stimulants | None |
| Servings | 30 (150 capsules) |
| ⚠ Allergen | Milk (VasoDrive-AP) |
| ⚠ Prop 65 | Lead warning disclosed |
The ginseng standardisation is worth noting. 70% ginsenosides is a high-grade extract — a raw ginseng powder with no standardisation figure tells you nothing about active content, and 400mg at 70% is a genuine dose rather than a label mention.
Capsules versus powder — the real decision
| Poppa Pump | Capsules | 1.5g Nitrosigine, nitrate, ACE-inhibitor peptides |
| NovaPump | Powder | 8g citrulline malate, 4g GlycerPump, five mechanisms |
| NITR-OX | Powder | 10g pure citrulline, best electrolytes |
Be clear about the trade-off. You cannot fit 8 to 10 grams of citrulline into capsules — that would be twenty or more pills. Capsule pump products necessarily rely on ingredients that work at milligram doses, which is exactly what Nitrosigine, VasoDrive and radish extract are.
So this is not a smaller version of a powder pump product. It is a different approach.
Choose Poppa Pump if: you travel, you already drink a pre-workout and do not want a second powder, or you simply will not mix another drink.
Choose a powder if: you want maximum citrulline and glycerol, which capsules cannot deliver.
They also stack well — Nitrosigine and citrulline raise arginine by different routes, so there is no redundancy.
How to take it
- Five capsules on an empty stomach, within an hour of training.
- Skip antibacterial mouthwash on training days.
- Also usable on rest days before breakfast — Nitrosigine's research involves multi-day use, and levels build with consistency.
- Stimulant-free, so it stacks with any pre-workout.
- Drink enough water. Pump ingredients work by moving fluid.
Who this is for
- Anyone who travels and cannot carry tubs of powder
- People already taking a pre-workout who do not want to mix a second drink
- Anyone who dislikes the taste or volume of pump powders
- People wanting a pump product they can take daily, including rest days
- Anyone stacking with an existing pre-workout — no stimulants, no citrulline overlap
Who this is not for
Anyone with a dairy allergy. VasoDrive-AP is casein-derived.
Anyone who wants maximum pump dosing. Capsules cannot hold 8 to 10g of citrulline — NovaPump or NITR-OX deliver considerably more raw material.
Anyone buying it for HEMO-Growth. See above.
Anyone who dislikes swallowing five capsules at a time.
Not vegan. Not for anyone under 18, pregnant or nursing. Discontinue two weeks before surgery, and speak to your doctor if you take blood pressure medication — several ingredients here affect vasodilation.
Stack it with: a powder pump product or your usual pre-workout. Different mechanisms, no overlap.
Frequently asked questions
What is Nitrosigine?
Inositol-stabilised arginine silicate. Arginine is the direct nitric oxide precursor but has poor oral bioavailability; buffering it with inositol and potassium silicate protects it from first-pass breakdown so it actually reaches circulation.
What is the arginine paradox?
Arginine should be the most effective NO booster, but oral doses are largely destroyed before absorption — and doses large enough to compensate cause stomach upset. That is why the industry moved to citrulline, and why Nitrosigine exists.
Does it contain dairy?
Yes. VasoDrive-AP is made from hydrolysed casein tripeptides, so this is milk-derived — unexpected in a capsule product and important if you have a dairy allergy.
Why does mouthwash matter?
The red radish extract is a nitrate source, and the first step of the nitrate pathway is performed by bacteria on your tongue. Antibacterial mouthwash kills them and blunts the effect.
What is HEMO-Growth?
An obscure ingredient described as fibroblast growth factors and activin, at 200mcg. Growth factors are proteins, and proteins are digested into amino acids when swallowed. There is very little published research — do not buy the product for this ingredient.
Can I stack it with a powder pump product?
Yes. Nitrosigine and citrulline raise arginine by different routes, so there is no redundancy.
Can I take it on rest days?
Yes. Nitrosigine research involves multi-day use, and levels build with consistent intake.
Why capsules rather than powder?
Convenience — but note capsules cannot hold gram-scale ingredients like citrulline or glycerol, so this relies on ingredients effective at milligram doses.
