Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Pump Black Cherry contains 5 active ingredients designed to support athletic performance and blood flow. L-citrulline is an amino acid that your body converts to another amino acid, L-arginine, which can help relax blood vessels.

Nitrosigine and GlycerPump (glycerol) are also included to support blood flow and performance during exercise. AstraGin and Huperzia serrata round out the formula, though we hold limited interaction data for AstraGin.

The powder also contains inactive ingredients — citric acid, malic acid, silica, natural and artificial flavors, sucralose, and acesulfame potassium — for taste and texture.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: athletic performance and workout support.
  • We looked for evidence on: Athletic performance, Muscle strength, exercise endurance, muscle recovery, blood flow.
  • The strongest evidence on file: Glycerol is rated "Possibly Effective" for Athletic performance (Natural Medicines).
  • Also on file: L-citrulline is rated "Possibly Effective" for Athletic performance.
  • Also on file: L-citrulline is rated "Insufficient Reliable Evidence To Rate" for Muscle strength.

L-citrulline is rated possibly effective for athletic performance. Glycerol is also rated possibly effective for athletic performance and likely effective for constipation, though at larger medicinal doses.

Effectiveness data isn't established in our records for Nitrosigine, AstraGin, or Huperzia serrata for athletic or performance purposes.

The evidence, ingredient by ingredient L-citrulline Glycerol Toothed Clubmoss

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

L-citrulline is generally well tolerated in healthy adults, though long-term safety isn't fully studied. The most common side effects are gastrointestinal — gastrointestinal discomfort, heartburn, and stomach upset.

Glycerol is also generally well tolerated in normal amounts, but larger doses can cause bloating, diarrhea, nausea, vomiting, dizziness, and headache. Huperzia serrata may cause nervous-system and digestive side effects including dizziness, nausea, and sweating.

The safety data advises against L-citrulline during pregnancy and breastfeeding. The same applies to Huperzia serrata — there isn't enough safety information, so it should be avoided during pregnancy and while breastfeeding.

For glycerol, there isn't enough specific safety data on medicinal amounts during pregnancy or breastfeeding; talk to your doctor for personalized advice. Data on AstraGin and Nitrosigine during pregnancy and breastfeeding is not on file.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 3 matched ingredients can interact with medications — Toothed Clubmoss, L-citrulline.
  • The most serious interaction on file is rated Moderate.
  • For scale: 397 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check your exact medications before you start, especially if you take blood pressure medication or erectile dysfunction drugs — L-citrulline may amplify their effects (Moderate severity). Also check with your pharmacist if you take anticholinergic drugs or cholinergic drugs like donepezil, which Huperzia serrata may interact with (Moderate severity).

We couldn't check interactions for Nitrosigine and AstraGin.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Pump Black Cherry is marketed for athletic performance, and L-citrulline and glycerol each have some evidence supporting that use. If you take blood pressure medication or an erectile dysfunction drug, talk to your pharmacist before starting — the L-citrulline could amplify their effects.

Same goes if you take any anticholinergic or cholinergic medication. Pregnant or breastfeeding?

Check with your doctor first.

Huperzia serrata2 drug types · 219 drugs

Anticholinergic Drugs

In animal models, toothed clubmoss and huperzine A, an active constituent of toothed clubmoss, reversed cognitive deficits induced by scopolamine. Theoretically, concurrent use of anticholinergic drugs and toothed clubmoss might decrease the effectiveness of toothed clubmoss or the anticholinergic drug.
Some anticholinergic drugs include atropine, benztropine (Cogentin), biperiden (Akineton), procyclidine (Kemadrin), and trihexyphenidyl (Artane).

Likelihood Possible Evidence D
Cholinergic Drugs

Huperzine A, a constituent of toothed clubmoss, has demonstrated acetylcholinesterase inhibitory properties. Theoretically, concurrent use of toothed clubmoss with cholinergic drugs might have additive effects and increase the risk of cholinergic side effects.
Cholinergic drugs include bethanechol (Urecholine), donepezil (Aricept), echothiophate (Phospholine Iodide), edrophonium (Enlon, Reversol, Tensilon), neostigmine (Prostigmin), physostigmine (Antilirium), pyridostigmine (Mestinon, Regonol), succinylcholine (Anectine, Quelicin), and tacrine (Cognex).

Likelihood Possible Evidence D
Huperzia serrata full monograph & interactions

L-Citrulline2 drug types · 178 drugs

Antihypertensive Drugs

Theoretically, concomitant use of L-citrulline with antihypertensive drugs might have additive effects and increase the chance of hypotension.
L-citrulline is converted to L-arginine, which can increase nitric oxide and cause vasodilation. However, a meta-analysis of 5 small clinical studies suggests that taking L-citrulline 3-6 grams daily for 1-8 weeks does not lower blood pressure when compared with control.

Likelihood Possible Evidence B
Phosphodiesterase-5 Inhibitors

Theoretically, concurrent use of phosphodiesterase-5 (PDE-5) inhibitors and L-citrulline might result in additive vasodilation.
L-citrulline is converted to L-arginine, which can increase nitric oxide and cause vasodilation. Theoretically, taking L-arginine with PDE-5 inhibitors might have additive vasodilatory and hypotensive effects. However, in studies evaluating the combined use of L-arginine and sildenafil for erectile dysfunction, hypotension was not reported.

Pump Black Cherry by Alani Nu: Common Questions

Does Pump Black Cherry by Alani Nu interact with any medications?
Yes. Based on its ingredients, Pump Black Cherry has a known interaction with 397 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Pump Black Cherry contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will this help me work out harder or longer?
L-citrulline and glycerol are both rated possibly effective for athletic performance. That means there's some evidence they may help, but the proof isn't rock-solid yet. How much they help you personally can vary.
What are the most common side effects?
The main ones are gastrointestinal — gastrointestinal discomfort, heartburn, and stomach upset from L-citrulline, and bloating, diarrhea, nausea, and dizziness from glycerol. These are generally mild, but they're worth knowing about.
Can I take this if I'm pregnant or breastfeeding?
The safety data advises against L-citrulline and Huperzia serrata during pregnancy and breastfeeding. For glycerol, there isn't enough specific data — talk to your doctor for personalized advice. We don't have pregnancy and breastfeeding data on file for Nitrosigine and AstraGin.
What's in here that actually does something?
L-citrulline helps your body produce nitric oxide, which relaxes blood vessels and may boost blood flow during exercise. Glycerol also supports hydration and athletic performance. Nitrosigine, AstraGin, and Huperzia serrata are also active ingredients, though effectiveness ratings aren't established in our data for some of them.
Is this safe to take long-term?
L-citrulline is generally well tolerated, but long-term safety isn't fully studied. The same caution applies to the other ingredients — we simply don't have extensive long-term data. If you plan to use this regularly, check with your pharmacist.
Why do I need to check my blood pressure medications with a pharmacist?
L-citrulline can theoretically add to how much your blood pressure medication lowers your blood pressure, which could make you dizzy or lightheaded. A quick check ensures your dose is safe when taking both together.
