What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 6 of its 19 active ingredients.
  • “Muscle GROWTH Blend” is a proprietary blend — the label doesn't break down how much of each component you get.
  • “Pro-Estro SUPPRESS Blend” is a proprietary blend — the label doesn't break down how much of each component you get.
  • “4-in-1 Test Support Matrix” is a proprietary blend — the label gives one combined amount (315 mg) without saying how much of each component you get.

Hardcore Testosterone Amplifier contains 19 active ingredients designed to support testosterone and muscle, including minerals, herbal extracts, and specialized blends. The key actives are zinc (for immune and hormonal function), BioPerine black pepper extract (for absorption), DHEA (a hormone precursor), ashwagandha root extract (an adaptogen), resveratrol (a plant compound), indole-3-carbinol (from cruciferous vegetables), cowhage seed extract (which contains levodopa), chrysin (a plant flavonoid), white button mushroom extract, calcium, sarsaparilla, oat extract, bladderwrack (a seaweed high in iodine), diindolylmethane, tribulus, and fenugreek.

Several are grouped as proprietary blends—Muscle GROWTH, Pro-Estro SUPPRESS, 4-in-1 Test Support Matrix, Activate T, T Absorption Agent, E-Fighter Agent, AndroTEST, and LaxoTest Complex—whose exact amounts aren't disclosed. The product also contains inactive ingredients: bovine gelatin, magnesium stearate, silicon dioxide, cellulose, and titanium dioxide.

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: Professional muscular development and testosterone support.
  • We looked for evidence on: Athletic performance, Muscle mass, Strength and endurance, Testosterone levels.
  • The closest evidence on file: Tribulus is rated "Possibly Ineffective" for Athletic performance (Natural Medicines).
  • Also on file: Aspartic Acid is rated "Insufficient Reliable Evidence To Rate" for Athletic performance.
  • Also on file: Dhea is rated "Insufficient Reliable Evidence To Rate" for Athletic performance.

The evidence varies widely by ingredient. Zinc is effective for zinc deficiency and likely effective for Wilson disease; it's possibly effective for acne, diabetes, and age-related macular degeneration.

Oat extract is likely effective for high cholesterol and heart health. DHEA is likely effective for vaginal atrophy and possibly effective for depression and aging skin.

Ashwagandha is possibly effective for anxiety, stress, and insomnia. Fenugreek is possibly effective for sexual function and diabetes.

Resveratrol, tribulus, and sarsaparilla are possibly effective for sexual dysfunction; however, tribulus was possibly ineffective for athletic performance, and resveratrol was possibly ineffective for cardiovascular disease and high cholesterol. For several ingredients—BioPerine (black pepper), chrysin, cowhage, bladderwrack, indole-3-carbinol, diindolylmethane, and white button mushroom—the evidence we hold is insufficient to rate their effectiveness.

The evidence, ingredient by ingredient Zinc Diindolylmethane Fenugreek

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 15 of the 17 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 17 of 17.
  • General safety write-ups exist for 17 of 17.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most ingredients are generally well tolerated in recommended amounts. Zinc is generally well tolerated below 40 mg daily but can cause abdominal cramps, diarrhea, metallic taste, nausea, and vomiting at higher doses; high long-term use raises concern for copper deficiency.

Ashwagandha, oats, and fenugreek are generally well tolerated short-term, though fenugreek can cause bloating, diarrhea, and flatulence. However, several ingredients carry cautions: DHEA is a hormone with the potential for long-term cancer risk and can cause acne, mood changes, and masculinization in women; cowhage contains levodopa (an active drug) and should be used under guidance; bladderwrack is high in iodine and can disrupt thyroid function; resveratrol may cause digestive upset at high doses.

Calcium is generally safe in recommended amounts. Pregnancy and lactation safety varies: zinc, BioPerine, oats, resveratrol, diindolylmethane, and calcium are likely safe; DHEA, ashwagandha, indole-3-carbinol, cowhage, bladderwrack, chrysin, and tribulus are not recommended due to insufficient data or hormone effects.

Fenugreek is not advised in pregnancy but is possibly safe while breastfeeding.

Why this rating?
  • 16 of the 17 matched ingredients can interact with medications — Tribulus, Resveratrol, Dhea, Sarsaparilla, Fucus Vesiculosus, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications; lithium; Parkinson's medications.
  • For scale: 1,628 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 HIV integrase inhibitors (dolutegravir, elvitegravir, bictegravir/emtricitabine/tenofovir alafenamide, or raltegravir) — calcium in this product may reduce their effectiveness significantly. Also double-check if you take blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel), antidiabetes or insulin, blood pressure drugs, antiseizure medications (phenytoin, mephenytoin), antidepressants, benzodiazepines, thyroid hormones, or theophylline.

No interactions are documented for arginine alpha-ketoglutarate and yacon, but we hold no data for these ingredients.

FenuPRO9 drug types · 389 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, fenugreek might have additive effects when used with anticoagulant or antiplatelet drugs.
Some of the constituents in fenugreek have antiplatelet effects in animal and in vitro research. However, common fenugreek products might not contain sufficient concentrations of these constituents for clinical effects. A clinical study in patients with coronary artery disease or diabetes shows that taking fenugreek seed powder 2.5 grams twice daily for 3 months does not affect platelet aggregation, fibrinolytic activity, or fibrinogen levels .

Likelihood Unlikely Evidence B
Antidiabetes Drugs

Theoretically, fenugreek seed might have additive hypoglycemic effects when used with antidiabetes drugs.
Clinical research shows that fenugreek seed can reduce fasting blood glucose and 2-hour postprandial glucose levels in adults with type 2 diabetes.

Likelihood Probable Evidence B
Clopidogrel (Plavix)

Theoretically, fenugreek seed might alter the clinical effects of clopidogrel by inhibiting its conversion to the active form.
Animal research shows that fenugreek seed 200 mg/kg daily for 14 days increases the maximum serum concentration of clopidogrel by 21%. It is unclear how this affects the pharmacokinetics of the active metabolite of clopidogrel; however, this study found that concomitant use of fenugreek seed and clopidogrel prolonged bleeding time by an additional 11%.

Likelihood Possible Evidence D
Metoprolol (Toprol)

Theoretically, fenugreek seed might have additive hypotensive effects when used with metoprolol.
Animal research shows that fenugreek seed 300 mg/kg daily for 2 weeks decreases systolic and diastolic blood pressure by 9% and 11%, respectively, when administered alone, and by 15% and 22%, respectively, when given with metoprolol 10 mg/kg.

Likelihood Probable Evidence B
Phenytoin (Dilantin)

Theoretically, fenugreek might decrease plasma levels of phenytoin.
Animal research shows that taking fenugreek seeds for 1 week decreases maximum concentrations and the area under the curve of a single dose of phenytoin by 44% and 72%, respectively. This seems to be related to increased clearance. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Sildenafil (Viagra)

Theoretically, concurrent use of sildenafil and fenugreek might reduce levels and therapeutic effects of sildenafil.
Animal research shows that taking fenugreek seeds for 1 week reduces maximum concentrations and the area under the curve of a single dose of sildenafil by 27% and 48%, respectively. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Theophylline

Theoretically, fenugreek may reduce the levels and clinical effects of theophylline.
Animal research shows that fenugreek 50 grams daily for 7 days reduces the maximum serum concentration (Cmax) of theophylline by 28% and the area under the plasma drug concentration-time curve (AUC) by 22%.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, fenugreek might have additive effects with warfarin and increase the international normalized ratio (INR).
Some fenugreek constituents have antiplatelet effects, although these might not be present in concentrations that are clinically significant. In one case report, a patient taking warfarin experienced an increased INR when starting to take fenugreek in combination with boldo.

Likelihood Possible Evidence D
Antihypertensive Drugs

Fenugreek may also have an additive effect on blood pressure-lowering medications. Studies on animals have shown that fenugreek seed can decrease both systolic and diastolic blood pressure by up to 22% when combined with metoprolol. Therefore, it is essential to monitor your blood pressure regularly if you are taking fenugreek and metoprolol together or any other antihypertensive drugs.

Likelihood Possible Evidence C

E-Fighter Agent3 drug types · 269 drugs

Diuretic Drugs

Theoretically, diindolylmethane might increase the risk of hyponatremia if used with sodium-depleting diuretics.
Large doses of diindolylmethane (600 mg daily) have been associated with two cases of asymptomatic hyponatremia in clinical research.

Likelihood Possible Evidence B
Estrogens

Theoretically, diindolylmethane might increase or decrease the effects of estrogens.
Diindolylmethane might have mild estrogenic or antiestrogenic effects. Theoretically, large amounts of diindolylmethane might interfere with hormone replacement therapy.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, diindolylmethane might lower serum levels of CYP1A2 substrates.
In vitro evidence suggests that diindolylmethane can induce CYP1A2. Theoretically, it might increase metabolism of CYP1A2 substrates and lower serum concentrations. This interaction has not been reported in humans.

Likelihood Unlikely Evidence D

Zinc10 drug types · 67 drugs

Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Theoretically, zinc might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide should be taken at least 2 hours before or 6 hours after zinc containing products.

Likelihood Probable Evidence D
Cephalexin (Keflex)

Zinc might decrease cephalexin levels by chelating with cephalexin in the gut and preventing its absorption.
A pharmacokinetic study shows that zinc sulfate 250 mg taken concomitantly with cephalexin 500 mg decreases peak levels of cephalexin by 31% and reduces the exposure to cephalexin by 27%. Also, taking zinc sulfate 3 hours before cephalexin decreases peak levels of cephalexin by 11% and reduces the exposure to cephalexin by 18%. By decreasing cephalexin levels, zinc might increase the risk of treatment failure. This effect does not occur when zinc is taken 3 hours after the cephalexin dose. To avoid an interaction, advise patients take zinc sulfate 3 hours after taking cephalexin.

Likelihood Probable Evidence B
Cisplatin (Platinol-Aq)

Theoretically, zinc might interfere with the therapeutic effects of cisplatin.
Animal research suggests that zinc stimulates tumor cell production of the protein metallothionein, which binds and inactivates cisplatin. It is not known whether zinc supplements or high dietary zinc intake can cause clinically significant interference with cisplatin therapy. Cisplatin might also increase zinc excretion.

Likelihood Possible Evidence D
Integrase Inhibitors

Theoretically, taking zinc along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Zinc is a divalent cation. Pharmacokinetic studies have shown that other divalent cations such as calcium and iron can decrease blood levels of the integrase inhibitor dolutegravir through chelation.

Likelihood Possible Evidence D
Penicillamine (Cuprimine, Depen)

Zinc might reduce the levels and clinical effects of penicillamine.
By forming an insoluble complex with penicillamine, zinc interferes with penicillamine absorption and activity. Zinc supplements reduce the efficacy of low-dose penicillamine (0.5-1 gram/day), but do not seem to affect higher doses (1-2.75 gram/day), provided dosing times are separated. Advise patients to take zinc and penicillamine at least 2 hours apart.

Likelihood Probable Evidence B
Quinolone Antibiotics

Zinc can decrease the levels and clinical effects of quinolones antibiotics.
Quinolones form complexes with zinc in the gastrointestinal tract, reducing absorption of both the quinolone and zinc if taken at the same time. Advise patients to take these drugs at least 2 hours before, or 4-6 hours after, zinc supplements.

Likelihood Probable Evidence B
Ritonavir (Norvir)

Zinc modestly reduces levels of ritonavir.
Clinical research shows that zinc might reduce serum ritonavir levels by chelating with ritonavir in the gut and preventing its absorption. In patients with HIV, ritonavir is taken with atazanavir to prevent the metabolism and increase the effects of atazanavir. A pharmacokinetic study shows that, in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate (Solvazinc tablets) 125 mg as a single dose or as multiple daily doses for 2 weeks reduces plasma levels of ritonavir by about 16%. However, atazanavir levels still remains high enough to prevent HIV virus replication. Therefore, the decrease in ritonavir levels is not likely to be clinically significant.

Likelihood Probable Evidence B
Tetracycline Antibiotics

Zinc might reduce levels of tetracycline antibiotics.
Tetracyclines form complexes with zinc in the gastrointestinal tract, which can reduce absorption of both the tetracycline and zinc when taken at the same time. Taking zinc sulfate 200 mg with tetracycline reduces absorption of the antibiotic by 30% to 40%. Demeclocycline and minocycline cause a similar interaction. However, doxycycline does not seem to interact significantly with zinc. Advise patients to take tetracyclines at least 2 hours before, or 4-6 hours after, zinc supplements to avoid any interactions.

Likelihood Probable Evidence B
Amiloride (Midamor)

Amiloride can modestly reduce zinc excretion and increase zinc levels.
Clinical research shows that amiloride can reduce urinary zinc excretion, especially at doses of 10 mg per day or more. This zinc-sparing effect can help to counteract zinc losses caused by thiazide diuretics, but it is unlikely to cause zinc toxicity at usual amiloride doses. The other potassium-sparing diuretics, spironolactone (Aldactone) and triamterene (Dyrenium), do not seem to have a zinc-sparing effect.

Likelihood Probable Evidence B
Atazanavir (Reyataz)

Zinc modestly reduces levels of atazanavir, although this effect does not seem to be clinically significant.
Clinical research shows that zinc might decrease serum atazanavir levels by chelating with atazanavir in the gut and preventing its absorption. Although a single dose of zinc sulfate (Solvazinc tablets) 125 mg orally does not affect atazanavir concentrations in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate 125 mg daily for 2 weeks reduces plasma levels of atazanavir by about 22% in these patients. However, despite this decrease, atazanavir levels still remain at high enough concentrations for the prevention of HIV virus replication.

Hardcore Testosterone Amplifier by PMD: Common Questions

Does Hardcore Testosterone Amplifier by PMD interact with any medications?
Yes. Based on its ingredients, Hardcore Testosterone Amplifier has a known interaction with 1,627 medications, including 24 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Hardcore Testosterone Amplifier contains 8 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.
Can I take this if I'm on blood pressure medication?
Not without checking first. Ashwagandha, tribulus, and fenugreek can theoretically lower blood pressure, which could add to your medication's effect and cause your pressure to drop too far. Talk to your pharmacist about whether it's safe to combine them.
Does this product contain hormones?
Yes. It contains DHEA, which is a hormone precursor that can shift your hormone levels and carry risks with long-term use, including a theoretical link to cancer. It also contains cowhage, which provides levodopa, an active drug-like compound. Both need professional oversight.
Is this safe to take while pregnant or breastfeeding?
No. Several ingredients—DHEA, ashwagandha, cowhage, bladderwrack, and tribulus—are not recommended in pregnancy or while breastfeeding due to insufficient safety data or hormone effects. Fenugreek is possibly unsafe in pregnancy but may be safe while breastfeeding if approved by your doctor. Talk with your provider first.
What are the most common side effects?
Zinc can cause nausea, diarrhea, and a metallic taste. Ashwagandha, fenugreek, resveratrol, and oats may cause digestive upset—bloating, gas, or diarrhea. DHEA can cause acne, insomnia, and mood changes, especially in women. Start with a lower dose and see how you feel.
Will this interact with my HIV medication?
Possibly, and it could be serious. Calcium in this product can reduce blood levels of HIV integrase inhibitors like dolutegravir and elvitegravir by up to 40%. Zinc may also affect ritonavir. You must check with your pharmacist or HIV doctor before starting.
Is the iodine content in bladderwrack a problem?
Bladderwrack is high in iodine, which can disrupt thyroid function—causing either high or low thyroid activity depending on your history. If you have or are at risk for thyroid disease, or take thyroid medications or antithyroid drugs, talk to your doctor before using this product.
