HelloPharmacist Scorecard of Test X180 Testosterone Booster by Force Factor

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 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Test X180 has four ingredients, three of which are vitamins. Vitamin B6 supports nerve and immune function.

Vitamin B12 helps with energy and red blood cell formation. Vitamin D regulates calcium and bone health, and plays a role in immune and heart function.

The fourth ingredient is a Growth Enhancement Matrix — a proprietary blend we can't break down by individual components.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: safely increase testosterone levels.
  • We looked for evidence on: Athletic performance, Erectile dysfunction (ED), Exercise-induced muscle damage, Fatigue, Testosterone deficiency, Male sexual function — and 1 related terms.
  • The closest evidence on file: Vitamin B12 is rated "Insufficient Reliable Evidence To Rate" for Fatigue (Natural Medicines).
  • Also on file: Vitamin D is rated "Insufficient Reliable Evidence To Rate" for Athletic performance, Erectile dysfunction (ED), Post-stroke fatigue, Muscle strength, and more.

The three vitamins in this product have established uses, but they're not marketed for testosterone. Vitamin B6 is effective for certain types of anemia and B6 deficiency itself, and possibly helpful for pregnancy-related nausea.

Vitamin B12 is effective for B12 deficiency and certain rare conditions. Vitamin D is effective for rickets, osteomalacia, and related bone disorders.

The product's testosterone-boosting claims aren't addressed in the ingredient data we hold.

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.

Vitamin B6 is safe at normal supplement doses, but high doses over a long time can damage nerves (sensory neuropathy); the data shows this risk rises with daily doses over 1000 mg or lifetime totals over 1000 grams. Common side effects at typical doses are uncommon but can include headache, nausea, and stomach pain.

Vitamin B12 is very well tolerated and has no established upper limit because your body excretes excess amounts. Vitamin D is safe at recommended doses, but very high doses over time can cause vitamin D toxicity with high blood calcium levels.

Pregnancy and breastfeeding safety data isn't on file for any of these ingredients in this product context.

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?
  • 3 of the 3 matched ingredients can interact with medications — Vitamin B12, Vitamin D, Vitamin B6.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications; Parkinson's medications.
  • For scale: 856 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 with your pharmacist if you take any blood pressure medications (moderate interaction with vitamin B6), seizure drugs like phenytoin or phenobarbital (moderate), amiodarone for heart rhythm (moderate), digoxin for the heart (moderate), verapamil or diltiazem for arrhythmias (moderate), atorvastatin for cholesterol (moderate), or metformin for diabetes (minor). No interactions are documented for the Growth Enhancement Matrix, since we hold no data for it.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product is a multivitamin blend with documented uses for vitamin deficiencies and bone health, not a proven testosterone booster. It's worth reconsidering if you take blood pressure drugs, seizure medications, heart medications like digoxin or verapamil, metformin, or atorvastatin — all have interactions with at least one ingredient.

Talk to your pharmacist before starting, especially if you're on any prescription.

Each ingredient & the kinds of drugs it affects

For each ingredient in Test X180 Testosterone Booster with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Vitamin D8 drug types · 715 drugs

Aluminum

Vitamin D might increase aluminum absorption and toxicity, but this has only been reported in people with renal failure.
The protein that transports calcium across the intestinal wall can also bind and transport aluminum. This protein is stimulated by vitamin D, which may therefore increase aluminum absorption. This mechanism may contribute to increased aluminum levels and toxicity in people with renal failure, when they take vitamin D and aluminum-containing phosphate binders chronically.

Likelihood Probable Evidence B
Atorvastatin (Lipitor)

Vitamin D might reduce absorption of atorvastatin.
A small, low-quality clinical study shows that taking vitamin D reduces levels of atorvastatin and its active metabolites by up to 55%. However, while atorvastatin levels decreased, total cholesterol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol levels did not substantially change. Atorvastatin is metabolized in the gut by CYP3A4 enzymes, and researchers theorized that vitamin D might induce CYP3A4, causing reduced levels of atorvastatin. However, this proposed mechanism was not specifically studied.

Likelihood Probable Evidence B
Calcipotriene (Dovonex)

Taking calcipotriene with vitamin D increases the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with vitamin D supplements might increase the risk of hypercalcemia.

Likelihood Probable Evidence D
Digoxin (Lanoxin)

Theoretically, hypercalcemia induced by high-dose vitamin D can increase the risk of arrhythmia from digoxin.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and digoxin concurrently.

Likelihood Possible Evidence D
Diltiazem (Cardizem, Others)

Theoretically, hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of diltiazem for arrhythmia.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically this could also occur with diltiazem. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and diltiazem concurrently.

Likelihood Probable Evidence B
Thiazide Diuretics

Theoretically, taking thiazide diuretics and high-dose vitamin D can increase the risk of hypercalcemia.
Thiazide diuretics decrease urinary calcium excretion, which could lead to hypercalcemia if vitamin D supplements are taken concurrently. This has been reported in people being treated with vitamin D for hypoparathyroidism, and also in elderly people with normal parathyroid function who were taking a thiazide, vitamin D, and calcium-containing antacids daily.

Likelihood Probable Evidence D
Verapamil (Calan, Others)

Hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of verapamil for arrhythmia.
Hypercalcemia due to high doses of vitamin D can reduce the effectiveness of verapamil in atrial fibrillation. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and verapamil concurrently.

Likelihood Probable Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Vitamin D might induce CYP3A4 enzymes and reduce the bioavailability of CYP3A4 substrates.
There is some concern that vitamin D might induce CYP3A4. In vitro research suggests that vitamin D induces CYP3A4 transcription. Additionally, observational research has found that increased UV light exposure and serum vitamin D levels are associated with decreased serum levels of CYP3A4 substrates such as tacrolimus and sirolimus, while no association between UV light exposure or vitamin D levels and levels of mycophenolic acid, a non-CYP3A4 substrate, was found. A small, low-quality clinical study shows that taking vitamin D reduces levels of the CYP3A4 substrate atorvastatin and its active metabolites by up to 55%; however, the clinical effects of atorvastatin were not reduced. While researchers theorized that vitamin D might induce CYP3A4, this proposed mechanism was not specifically studied.

Likelihood Possible Evidence D

Vitamin B65 drug types · 210 drugs

Amiodarone (Cordarone)

Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.

Likelihood Possible Evidence B
Phenobarbital (Luminal)

High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Levodopa

Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.

Likelihood Unlikely Evidence D

Vitamin B121 drug type · 20 drugs

Metformin (Glucophage)

Metformin, a common medication used to manage type 2 diabetes, has been associated with lower vitamin B12 levels in some individuals. Prolonged use of metformin can interfere with the absorption of B12 in the digestive system, potentially leading to a deficiency in this essential vitamin.

Test X180 Testosterone Booster by Force Factor: Common Questions

Does Test X180 Testosterone Booster by Force Factor interact with any medications?
Yes. Based on its ingredients, Test X180 Testosterone Booster has a known interaction with 855 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Test X180 Testosterone Booster contains 4 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 build muscle or boost testosterone?
The product name suggests a testosterone benefit, but the ingredient data we have covers the three vitamins and a proprietary blend we can't assess. The vitamins themselves — B6, B12, and D — have established uses for deficiency and bone health, not testosterone or muscle gain.
Is vitamin B6 safe in this product?
Vitamin B6 is well tolerated at normal supplement doses. But at very high daily doses (over 1000 mg) or lifetime totals (over 1000 grams), it can cause nerve damage. You'd want to know the dose in this product and talk to your pharmacist if you're taking it long-term or alongside other B6 sources.
Can I take this if I'm on blood pressure medication?
Vitamin B6 may lower blood pressure on its own, so taking it with blood pressure drugs could have an additive effect — meaning your pressure might drop more than intended. Run your specific medication through the checker on this page and talk to your pharmacist before adding this product.
Is this safe in pregnancy?
We don't have pregnancy or breastfeeding safety data on file for these ingredients in this product context. Vitamin B6 is sometimes used for morning sickness, but only under a doctor's guidance. Talk with your doctor or pharmacist for personalized advice if you're pregnant or nursing.
What's the Growth Enhancement Matrix?
It's a proprietary blend, which means the exact ingredients and amounts aren't listed separately. We can't check it for interactions or effectiveness because we don't have data on its contents.
Are there any fillers in this?
Yes — the inactive ingredients include gelatin, magnesium stearate, silicon dioxide, titanium dioxide, and FD&C Blue #1 (a food dye). These are common capsule materials and binders.
