HelloPharmacist Scorecard of Testmax Testosterone Boost by Malemax

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Testmax contains a single active ingredient: tribulus powder. Tribulus is a plant extract used traditionally to support sexual function and athletic performance.

The capsule also holds two inactive ingredients — cellulose and magnesium stearate — which are fillers and binders that hold the capsule together.

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

This product doesn't appear to be marketed for a specific use, so we graded Tribulus's overall clinical evidence instead.

Moderate

Some clinical evidence supports Tribulus for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Sexual dysfunction — rated "Possibly Effective" (Natural Medicines).

The evidence for tribulus and sexual dysfunction is mixed but leans toward possibly effective — some clinical research supports it, though more rigorous trials would strengthen the case. For athletic performance, the data suggests it's possibly ineffective.

As for benign prostatic hyperplasia (enlarged prostate), we don't have enough reliable evidence to rate whether it works.

The evidence, ingredient by ingredient Tribulus

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Tribulus is generally well tolerated short-term in healthy adults, but quality data on long-term safety are limited. Rare serious side effects have been reported, including liver or kidney injury, seizures, and a persistent painful erection with sexual dysfunction; cases of lung collapse and bronchial polyps from the fruit's spines have also occurred.

More commonly, some people report stomach pain, cramping, nausea, vomiting, diarrhea, or constipation — though one study found these rates were similar to placebo. One case report described severe weakness, seizures, liver inflammation, and acute kidney failure after drinking 2 liters of tribulus water daily for two days; the patient improved after stopping it and undergoing dialysis.

The safety data advises against tribulus during pregnancy because it may affect hormones and safety is not established. Avoid it while breastfeeding due to lack of reliable safety information.

Side effects, ingredient by ingredient Tribulus

Meds to double-check

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?
  • 1 of the 1 matched ingredient can interact with medications — Tribulus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; lithium.
  • For scale: 259 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.

Before taking Testmax, check whether you're on blood pressure medications (antihypertensives), diabetes medications (antidiabetes drugs), or lithium — all at Moderate severity. Tribulus can lower blood pressure and blood sugar, and may increase lithium levels.

Your doctor or pharmacist can tell you whether it's safe to combine.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Tribulus might help with sexual dysfunction, though the evidence is modest. If you take medications for blood pressure, diabetes, or lithium, check with your doctor or pharmacist before adding this — tribulus could shift how those drugs work.

Pregnancy and breastfeeding are times to skip it. Talk it over with your own healthcare provider to decide if it's right for you.

Antidiabetes Drugs

Taking tribulus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that Tribulus can lower blood glucose levels in adults with type 2 diabetes who are taking antidiabetes medications.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking tribulus with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that tribulus can lower blood pressure by inhibiting angiotensin-converting enzyme (ACE). Tribulus has also demonstrated hypotensive effects in pre-hypertensive adults.

Likelihood Possible Evidence D
Lithium

Theoretically, tribulus might increase the levels and clinical effects of lithium.
Tribulus is thought to have diuretic properties. Due to these potential diuretic effects, tribulus might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Does Testmax Testosterone Boost by Malemax interact with any medications?
Yes. Based on its ingredients, Testmax Testosterone Boost has a known interaction with 259 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Testmax Testosterone Boost contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Does tribulus actually work for sexual dysfunction?
The evidence says possibly effective — some clinical research supports it, but stronger trials would help confirm it. Results vary from person to person.
Can I take this while pregnant?
No — the safety data advises against it during pregnancy because tribulus may affect hormones and safety hasn't been established. Talk with your doctor about other options.
Is it safe to breastfeed while taking tribulus?
The data recommend avoiding it while breastfeeding because there isn't enough reliable safety information. Your doctor or pharmacist can discuss safer alternatives.
What side effects might I notice?
Tribulus is generally well tolerated, but some people report stomach discomfort like cramping, nausea, vomiting, diarrhea, or constipation. Serious side effects are rare but have included liver or kidney injury and seizures.
Will this boost my athletic performance?
The evidence suggests tribulus is possibly ineffective for athletic performance, so it's unlikely to help you in that way.
Can I take this long-term?
Short-term use in healthy adults seems well tolerated, but long-term safety data are limited — talk with your pharmacist about how long you plan to use it.
