What we tested for, and what most supplement brands don't
The supplement industry has a credibility problem.
The FDA does not approve supplements before they go on sale. Anyone can put a product on a shelf with a label that says it contains a clinical dose of zinc and vitamin D, and walk away. By the time the FDA catches up, the bottle is in your medicine cabinet.
The way you fix that, and the way every supplement brand worth trusting fixes it, is by sending your product to an independent lab and publishing what comes back. Not the parts that make you look good. Everything.
So that’s what we did. We sent Total Men’s Package, lot 2025196, to Eurofins, the largest food, supplement, and pharmaceutical testing network in the world, with USDA, FDA, and ISO 17025 accreditation. We asked them to test for heavy metals, microbials, pathogens, and banned-substance adulterants, and to verify the label claims for the seven vitamins and minerals. Twelve pages of results.

Verifying what's on the label
This is the most basic claim a supplement makes, that what’s on the label is what’s in the bottle. And it’s not a given. A 2017 USDA and NIH analysis of adult multivitamins found that measured amounts often differed from the label, mostly running above it, by about 25% for selenium and iodine.
Eurofins measured the seven vitamins and minerals on our label. The botanicals (tongkat ali, shilajit, fenugreek, ashwagandha) and the organ blend were not assayed for potency in this report. Each value below is per 7-capsule serving:
- Vitamin D3: 77.2 mcg measured (label 50 mcg; spec ≥ 45 mcg), PASS
- Vitamin K2-MK7: 100 mcg (label 100 mcg; spec ≥ 90 mcg), PASS
- Vitamin K1: 417 mcg (label 400 mcg; spec ≥ 360 mcg), PASS
- Boron: 10.9 mg (label 10 mg; spec ≥ 9 mg), PASS
- Copper: 0.908 mg (label 1 mg; spec ≥ 0.9 mg), PASS
- Zinc: 14.8 mg (label 15 mg; spec ≥ 13.5 mg), PASS
- Magnesium: 198 mg (label 200 mg; spec ≥ 180 mg), PASS
The methods used: ICP Emission Spectrometry per AOAC 984.27, 985.01, 2011.14. Vitamins by HPLC fast method.
Heavy metals
Almost any supplement that contains plant-derived ingredients can pick up trace heavy metals from the soil. The question isn’t are they there, it’s how far below the safety limit.
USP Chapter <2232> sets daily intake limits for the four heavy metals of greatest concern: arsenic, cadmium, lead, and mercury. Eurofins also measured chromium. The percentages below show what fraction of the specification limit on the Eurofins report a single serving of Total Men’s Package represents; the arsenic, cadmium, lead, and mercury results are also well below the USP <2232> limits:
- Arsenic: 5.85% of limit
- Lead: 5.64% of limit
- Chromium: 8.05% of limit
- Cadmium: < 0.69% of limit
- Mercury: < 1.41% of limit
For context: Consumer Reports has tested protein powders that exceeded heavy metal limits. We’re an order of magnitude below them.
Pathogens, the recall risk
The single biggest cause of supplement recalls in the U.S. is microbial contamination. Eurofins ran the full USP pathogen panel:
- E. coli: Absent in 10 g
- Salmonella: Absent in 10 g
- Staphylococcus aureus: Absent in 10 g
- Yeast and mold: < 100 CFU/g (limit is 100,000)
- Aerobic plate count: < 100 CFU/g (limit is 10,000,000)
The adulterant panel, the one that catches the bad actors
This is the test that almost no consumer-facing supplement brand voluntarily runs. Within the men’s health and testosterone-support category, there’s a long, documented history of brands spiking products with banned compounds, SARMs, designer steroids, prohormones, that produce real but unsafe effects, especially over time.
Eurofins ran a 22-compound panel of sports-nutrition adulterants: Ostarine, Ligandrol, RAD140, Stanozolol, Methasterone (Superdrol), GW1516, Ibutamoren, Methyl-1-testosterone, Dehydrochloromethyltestosterone, and a dozen others. Every single one came back “Not Detected”.
If you take supplements and care about anti-doping compliance, or just don’t want surprise endocrine effects, this panel is a useful starting point.
What this means
All seven vitamins and minerals on the label passed the report's specification (at least 90% of the label amount). Vitamin D3, K1 and boron measured above the label amount, K2 matched it, and copper, zinc and magnesium came in just under it (0.908 of 1 mg, 14.8 of 15 mg, 198 of 200 mg). The pathogens are absent. The heavy metals are nowhere near the limit. None of the 22 screened adulterants was detected.
That sounds like the bare minimum. It is. It’s also the bar that most of the men’s supplement category fails to clear.
We’ll send every batch we make to Eurofins. Each one gets its own page on the site. The certificate is downloadable. Click through, scroll the PDF, send it to your doctor.
This is the level of evidence we hold ourselves to. It’s the bar we want the men’s supplement category to meet. If it raises the bar elsewhere, even better.
