HelloPharmacist Scorecard of Peak Physicor by MTS Nutrition

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Peak Physicor contains 2 active ingredients. The first is PhysiCor, a fenugreek extract used to support sexual function and blood sugar control.

The second is PeakO2, which we have no data on. The capsule also contains inactive ingredients—cellulose, magnesium stearate, and silicon dioxide—which are fillers and binders.

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: Build lean mass, lose fat, perform better.
  • We looked for evidence on: Athletic performance, Muscle strength, Obesity, Body composition, Fat loss, Strength gain.
  • The closest evidence on file: Fenugreek is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Fenugreek is rated "Insufficient Reliable Evidence To Rate" for Muscle strength, Obesity.

Fenugreek (the active extract in PhysiCor) is rated Possibly Effective for sexual dysfunction, sexual arousal, dysmenorrhea (menstrual pain), and diabetes based on the evidence we hold. We have no effectiveness data on file for PeakO2, so we can't speak to what it does or how well it works.

The evidence, ingredient by ingredient 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 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.

Fenugreek seed is generally well tolerated at food amounts, but supplement doses can cause side effects—the most common are bloating, diarrhea, stomach upset, flatulence, and nausea. Rarely, severe allergic reactions including swelling of the throat (angioedema), airway spasm (bronchospasm), and shock have occurred.

Fenugreek is rated Likely Unsafe in pregnancy because it may affect the uterus. For breastfeeding, the evidence suggests it's possibly safe, though if you're considering it to boost milk supply, talk with your provider first since the evidence is limited.

One unusual side effect: consuming fenugreek during or just before pregnancy can cause the newborn to have an unusual body odor that could be mistaken for a genetic condition, though this appears temporary.

Side effects, ingredient by ingredient Fenugreek

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 — Fenugreek.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 389 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 Peak Physicor, double-check if you use blood thinners (anticoagulants) like warfarin or antiplatelet drugs like clopidogrel—fenugreek may increase bleeding risk. Also check if you take diabetes medications, theophylline, phenytoin, sildenafil, or beta-blockers like metoprolol.

These are Moderate-severity interactions. We hold no interaction data for PeakO2, the second active ingredient.

The bottom line

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

Peak Physicor may be worth considering if you're interested in supporting sexual function or managing blood sugar, and you don't take blood thinners, diabetes drugs, or certain other medications. If you're pregnant, avoid it—the safety data advises against medicinal use.

Before starting, check your medications with the tool on this page, especially if you take anything for blood clotting, blood pressure, seizures, or diabetes. Talk to your pharmacist about whether this product is right for you.

PhysiCor9 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.

Peak Physicor by MTS Nutrition: Common Questions

Does Peak Physicor by MTS Nutrition interact with any medications?
Yes. Based on its ingredients, Peak Physicor has a known interaction with 389 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Peak Physicor contains 2 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 pregnant?
No. Fenugreek is rated Likely Unsafe during pregnancy because it may affect the uterus. The data advises against medicinal use while pregnant. Talk with your doctor or pharmacist about safer options.
Is fenugreek safe while breastfeeding?
The evidence suggests it's possibly safe during lactation. However, if you're thinking about using it to boost milk supply, the evidence for that is limited—discuss it with your provider first to make sure it's right for you.
What are the most common side effects?
The most common side effects from fenugreek are bloating, diarrhea, stomach upset, flatulence, and nausea. Rare but serious allergic reactions—including throat swelling, airway spasm, and shock—can occur. Stop and seek help immediately if you have trouble breathing or severe swelling.
Does this product actually work for sexual dysfunction?
Fenugreek is rated Possibly Effective for sexual dysfunction and sexual arousal based on the evidence we hold, meaning there's some research support but it's not conclusive. Results vary from person to person.
Will this help my blood sugar?
Fenugreek is rated Possibly Effective for diabetes. Research shows it can reduce fasting blood sugar levels in people with type 2 diabetes, but it's not a replacement for your diabetes medications—and it may actually add to their blood-sugar-lowering effect, so talk with your doctor.
What's PeakO2?
PeakO2 is the second active ingredient in this product, but we have no interaction data or effectiveness information on file for it. Your pharmacist may have more details about what it's designed to do.
