HelloPharmacist Scorecard of Strength Mass by American Metabolix

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.

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 4 of its 9 active ingredients.
  • “Aphrodisiac Blend” is a proprietary blend — the label gives one combined amount (331 mg) without saying how much of each component you get.

Strength Mass contains nine ingredients, most of them herbal extracts and plant compounds aimed at muscle and performance support. The active ingredients are Ashwagandha extract (traditionally used for stress and sleep), Safed Musli (used in traditional medicine for athletic performance and muscle strength), Mucuna Pruriens — also called cowhage — which contains levodopa, Epiandrosterone (a hormone-like compound), Stinging Nettle extract, Indole-3-Carbinol (a compound from cruciferous vegetables), 5A-Hydroxy-Laxogenin, Adrostenolone, Deer Antler extract, and an Aphrodisiac Blend.

There are no inactive ingredients (fillers or binders) listed.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Strength, muscle mass, and athletic performance.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Muscle strength, Muscle hypertrophy, Lean body mass, Strength gains.
  • The closest evidence on file: Deer Velvet is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Ashwagandha is rated "Insufficient Reliable Evidence To Rate" for Athletic performance.
  • Also on file: Safed Musli is rated "Insufficient Reliable Evidence To Rate" for Athletic performance, Muscle strength.

The evidence for this product's ingredients is quite limited. Ashwagandha has possibly effective evidence for insomnia, anxiety, stress, and generalized anxiety disorder, but the other ingredients lack solid proof.

Safed Musli, Mucuna Pruriens, Epiandrosterone, Stinging Nettle, Indole-3-Carbinol, and Deer Antler all have insufficient reliable evidence for their marketed uses like muscle strength, athletic performance, or erectile dysfunction in our data. That doesn't mean they don't work — it means high-quality human studies are either missing or inconclusive.

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 4 of the 7 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 7 of 7.
  • General safety write-ups exist for 7 of 7.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Ashwagandha is generally well tolerated short-term in healthy adults, though long-term safety data are limited. The most common side effects are diarrhea, gastrointestinal upset, nausea, and vomiting, though these are uncommon at typical doses.

Rare serious effects include liver damage and a case of reversible cerebral vasoconstriction with bleeding. Mucuna Pruriens seems to have few adverse effects at typical use; the main reported ones are gastrointestinal (diarrhea, flatulence, nausea, vomiting) and headache, with insomnia reported in about 3% of people in one trial.

Stinging Nettle is generally well tolerated and may cause constipation or diarrhea. Indole-3-Carbinol causes diarrhea and has been linked to unsteadiness and tremor at higher doses.

Epiandrosterone, a hormone-related compound, carries real potential for androgenic side effects but has limited safety data. Safety data for Safed Musli, 5A-Hydroxy-Laxogenin, Adrostenolone, and Deer Antler extract are not detailed in our data.

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 5 of the 7 matched ingredients can interact with medications — Stinging Nettle, Deer Velvet, Ashwagandha, Cowhage, Indole-3-carbinol.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium; Parkinson's medications.
  • For scale: 1,497 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.

Stop and check before taking this if you use monoamine oxidase inhibitors (MAOIs) — there's a Major risk of hypertensive crisis. Also double-check with your pharmacist or doctor if you take methyldopa, levodopa, any blood pressure medications, sedatives or benzodiazepines, diabetes drugs, blood thinners (especially warfarin), antipsychotics, tricyclic antidepressants, thyroid hormones, estrogen therapy, or lithium.

Some of these carry Major-severity risks; others Moderate.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with insufficient evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This product is a multi-ingredient blend targeting muscle and performance, but the evidence for most of its ingredients is sparse. More importantly, it has serious interactions with certain blood pressure and psychiatric medications, and should not be taken by anyone using MAOIs.

If you take any prescription medication — especially for blood pressure, blood sugar, mood, blood clotting, or antipsychotic purposes — talk to your pharmacist or doctor before starting this product.

Ashwagandha extract10 drug types · 1,372 drugs

Antidiabetes Drugs

Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
There is preliminary clinical evidence suggesting that ashwagandha might lower blood glucose levels. Theoretically, ashwagandha might have additive effects when used with antidiabetes drugs and increase the risk of hypoglycemia.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure. Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.

Likelihood Possible Evidence D
Benzodiazepines

Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin). This may also occur with other benzodiazepines.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, taking ashwagandha with hepatotoxic drugs might increase the risk of liver damage.
Ashwagandha has been linked to cases of acute hepatitis, liver failure, hepatic encephalopathy, autoimmune hepatitis, the need for liver transplantation, and death due to liver failure.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Ashwagandha has demonstrated immunostimulant effects in humans. Animal research has shown that ashwagandha can attenuate the immunosuppression caused by cyclophosphamide.

Likelihood Possible Evidence D
Thyroid Hormone

Ashwagandha might increase the effects and adverse effects of thyroid hormone.
Concomitant use of ashwagandha with thyroid hormones may cause additive therapeutic and adverse effects. Preliminary clinical research and animal studies suggest that ashwagandha boosts thyroid hormone synthesis and secretion. In one clinical study, ashwagandha increased triiodothyronine (T3) and thyroxine (T4) levels by 41.5% and 19.6%, respectively, and reduced serum TSH levels by 17.4% from baseline in adults with subclinical hypothyroidism.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, ashwagandha might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that ashwagandha extract induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, ashwagandha might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that ashwagandha extract induces CYP3A4 enzymes.

Likelihood Possible Evidence D
Serotonergic Drugs

Some animal studies have reported that ashwagandha can enhance serotonergic transmission by altering certain serotonin (5-HT) receptors. However, there is no evidence to suggest that ashwagandha increases the risk of serotonin-related effects, and there have been no published case reports of serotonin syndrome when combined with other serotonergic drugs. Nevertheless, due to the lack of extensive studies on the matter and the fact that ashwagandha appears to affect serotonergic pathways, it would be prudent to exercise caution when combining it with drugs that affect serotonin.

Anticoagulant/Antiplatelet Drugs

Theoretically, indole-3-carbinol might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
In vitro research shows that indole-3-carbinol inhibits platelet aggregation.

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

Mucuna Pruriens8 drug types · 193 drugs

Levodopa

Concomitant use can increase the risk of levodopa-related adverse effects.
Cowhage contains levodopa. Some cowhage products have been standardized to contain 75-400 mg of levodopa per dose.

Likelihood Likely Evidence D
Methyldopa (Aldomet)

Theoretically, concomitant use of cowhage and methyldopa might increase the risk of hypotension.
Cowhage contains levodopa. Use of levodopa with methyldopa might cause additive hypotension. In addition, methyldopa may inhibit peripheral decarboxylation of levodopa and increase levodopa levels in the central nervous system; avoid using.

Likelihood Probable Evidence D
Monoamine Oxidase Inhibitors (Maois)

Theoretically, concomitant use of cowhage and non-selective MAOIs might increase the risk of hypertensive crisis.
Cowhage contains levodopa. Use of levodopa with non-selective MAOIs might cause hypertensive crisis. However, this interaction has not been reported with MAO-B selective inhibitors such as selegiline.

Likelihood Probable Evidence D
Anesthesia

Theoretically, concomitant use of cowhage and anesthesia might increase the risk of arrhythmias.
Cowhage contains levodopa. Use of levodopa with cyclopropane or halogenated hydrocarbon anesthesia has led to arrhythmias. Other anesthetics have not been implicated. Use other anesthetics in patients taking cowhage or tell patients to stop taking cowhage at least 2 weeks before surgery.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of cowhage and antidiabetes drugs might increase the risk of hypoglycemia.
Animal research shows that cowhage might have hypoglycemic effects.

Likelihood Possible Evidence D
Antipsychotic Drugs

Theoretically, use of cowhage might decrease the clinical effects of antipsychotic drugs.
Cowhage contains levodopa. Use of levodopa might counteract the antidopaminergic effects of antipsychotic medications.

Likelihood Possible Evidence D
Guanethidine (Ismelin)

Theoretically, concomitant use of cowhage and guanethidine might increase the risk of hypotension.
Cowhage contains levodopa. Use of levodopa with guanethidine might cause additive hypotension; avoid using.

Likelihood Probable Evidence D
Tricyclic Antidepressants (Tcas)

Theoretically, use of TCAs might reduce the levels and clinical effects of cowhage.
Cowhage contains levodopa. Use of TCAs might reduce the absorption of levodopa. Some case reports describe patients that developed hypertension and dyskinesia when taking both levodopa and TCAs.

Stinging Nettle extract4 drug types · 164 drugs

Antidiabetes Drugs

Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Clinical research shows that stinging nettle might decrease blood glucose levels in patients with diabetes.

Likelihood Possible Evidence B
Diuretic Drugs

Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.

Likelihood Possible Evidence D
Lithium

Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Stinging nettle contains a significant amount of vitamin K. When taken in large quantities, this might interfere with the activity of warfarin.

Strength Mass by American Metabolix: Common Questions

Does Strength Mass by American Metabolix interact with any medications?
Yes. Based on its ingredients, Strength Mass has a known interaction with 1,496 medications, including 17 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Strength Mass contains 9 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 Strength Mass if I'm on blood pressure medication?
Ashwagandha in this product may lower blood pressure and cause dizziness, so combining it with blood pressure drugs could increase that risk. Talk to your pharmacist or doctor before starting — they can monitor you or adjust your dose if it's safe to use together.
Does this product contain any fillers or inactive ingredients?
No — the product facts show no inactive ingredients listed.
Is Strength Mass safe to take while pregnant or breastfeeding?
No. Ashwagandha is traditionally thought to risk miscarriage and should be avoided in pregnancy. Mucuna Pruriens is best avoided because of its dopamine effects, and its levodopa can lower prolactin and reduce milk supply while breastfeeding. Epiandrosterone and other hormone-related ingredients in this blend are not recommended during either pregnancy or breastfeeding. Talk to your doctor or pharmacist for personalized advice.
What is Mucuna Pruriens, and why is it in here?
Mucuna Pruriens, also called cowhage, is a plant that naturally contains levodopa — an active compound similar to a drug. It's included for muscle and performance support, but because it contains this drug-like substance, you need to be careful about combining it with other medications, especially blood pressure drugs and psychiatric medications.
Does this product have evidence that it actually works for muscle growth?
Not really. Ashwagandha has some evidence for stress and sleep, but most of the other ingredients — Safed Musli, Epiandrosterone, and the rest — don't have reliable human studies showing they work for muscle strength or athletic performance in our data.
What are the most common side effects?
Ashwagandha may cause diarrhea, nausea, or vomiting at higher doses. Mucuna Pruriens may cause gastrointestinal upset (diarrhea, flatulence, nausea), and Indole-3-Carbinol commonly causes diarrhea. At very high doses, Indole-3-Carbinol has caused unsteadiness and tremor in some people.
