One product, one panel, one record.
Xymogen ProbioMax Complete 350B, 15 stick packs — label audit
Eighteen designators, eighteen per-strain CFU figures, and they sum to exactly 350 billion — the best label disclosure in its batch. Which is what makes it possible to see that 64% of the dose sits in just two strains, and that the only potency basis printed anywhere attaches to a 650 billion at-manufacture figure rather than to the 350 billion on the front of the box.
This page is an audit of a label. It records what this product’s panel discloses, what of that could be checked against a primary record, and what could not. The score below ranks this product on that disclosure and on nothing else.
The record this page rests on
- NIH label record
- Label read on
- The most recent dated artefact behind this page. Labels change; this is how old our reading of it is.
- Cohort
- Addendum — outside the founding denominators Audited 2026-07-31, after the founding cohort of 27 was frozen. It sits outside every D27 denominator this site publishes.
- How deep this went
- Label audit — the lighter pass What the label says, what basis it gives for its CFU number, whether the strains are coded, whether a government label record exists — checked and published. No full claim inventory was written for this SKU. It is a real result, and it is a shallower one than the teardowns above it, which is why the page says so before you weigh it against them.
The Label Verifiability Score for this product
88.9 out of 100
Rank 21 of the 154 products in this audit the rubric can score.
The score measures one thing: how much of what you are buying this company tells you, and how much of that survives being checked against a source that is not the company. It does not measure whether the product works — this site holds no efficacy data of its own, and 0 of 294 organism slots in the founding cohort carry a strain with a human randomised trial for any male-specific outcome, so nobody in this category has evidence that would support a ranking by effect.
Computed over 66% of the rubric by weight — the share of the five questions below this record could answer. The remaining 2 questions are unanswered, and unanswered is not nought: they leave the divisor rather than dragging the score down. That share travels with the number and is never dropped — this score over 66% of the weight and the same score over all of it are different claims.
| Component | Weight | What was counted, and where | Fraction | Weight × fraction |
|---|---|---|---|---|
| Strain identity printed on the panel | 0.24 | 18 of 18 organism slots carry a printed strain designator. | 18 / 18 = 1.0000 | 0.2400 |
| Per-organism amount printed | 0.20 | 18 of 18 organism slots have an amount of its own; the rest are inside a blend total. | 18 / 18 = 1.0000 | 0.2000 |
| What the CFU count is measured against | 0.22 | Potency basis "at-manufacture": CFU figure printed yes, single basis stated yes, basis reaches expiry no — 2 of 3. | 2 / 3 = 0.6667 | 0.146667 |
| Printed designators that lead to a human trial | 0.20 | Only 2 of 18 designators on this panel have been searched — below the 50% coverage a published share requires. A ratio over 2 slots would describe our sampling, not the label. | Not answered | — excluded from the divisor, not counted as nought |
| Certification confirmed at the issuer’s own register | 0.14 | Every certification on this record is brand-asserted with the register unreachable, or not yet queried. An unreachable register is a fact about the verification infrastructure, not about this brand, so it may not move its position. | Not answered | — excluded from the divisor, not counted as nought |
0.586667 — the last column added up — divided by 0.66, the weight this record could answer, is 0.8889. Multiplied by 100 and rounded to one decimal, that is the 88.9 above.

What this label discloses
Everything in this table is what the product itself states — on the printed panel, on the brand’s own page, or in the label record the manufacturer filed. Nothing in it is checked yet; checking is the next section.
| Disclosure | As recorded |
|---|---|
| CFU as printed | 350 billion CFU‡ per stick pack |
| What that count is measured against | At manufacture only |
| Strain designators | All organisms coded |
| Organism slots transcribed here | 18 — the full panel |
| Marketed as | Unisex |
Two footnotes, verbatim from DRS-307: "‡Colony-Forming Units" and "††Formulated with 650 billion CFU‡ at time of manufacture". The directions read "Dissolve the contents of 1 stick pack (350 billion CFU‡)†† into 1-2 oz of water…". So the only basis language on this label attaches to the 650 billion at-manufacture figure, and the 350 billion per-serving claim — the number on the front of the box and in the product name — carries no stated basis at all. Read it fairly in both directions: disclosing a roughly 1.86x manufacturing overage is unusually honest, and most brands bury the overage and print the manufacture number as the headline. The structure strongly implies 350 billion is a through-shelf-life figure. Implication is not a guarantee, and the label never says "at expiration". Recorded as at-manufacture because that is the only basis the label actually states; the ambiguity is the finding.
The panel’s own words on potency, verbatim.
The count is stated at time of manufacture only. The panel makes no commitment about what is alive when you swallow it.
Every organism on the panel carries a printed strain designator. Whether those designators lead anywhere is a separate question, answered below.
| Organism as printed | Designator as printed | Quantity as printed | What the designator resolves to | The query we ran |

What of that is verifiable
A disclosure is verifiable when a reader can open a record that neither we nor the brand controls and see the same thing. Below is every dated artefact this page rests on. What is absent from this list is not verified, however reasonable it sounds.

It also covers both the stick-pack and capsule formats on one sheet, which is how the two product names got tangled.

How many of its strains have a human trial for what it is sold for
Across the frozen founding cohort, 0 of 294 organism slots (0.0%) carry an organism with a human randomised controlled trial for any male-specific outcome. Not for this product — for all 27 of the founding teardowns, taken together. That is the number to hold against any men’s probiotic, including this one.
Two further founding-cohort figures for context: only 43 of 294 organism slots carry a strain with any human RCT at all under the exact code printed on the label, and only 2 of 27 products have a published human trial of the finished formula — the thing actually in the bottle. All three figures divide by the frozen cohort of 27 teardowns and 294 organism slots, never by every teardown on this site.
For this product specifically, 2 organism slots carry a strain with a human RCT under the exact designator printed on the label.
A word on what a designator has to clear before it counts here. The organism must be named with the exact strain code that appears in the trial, the trial must be in humans, and the code must return that trial when a reader searches it. A species name does not qualify: the trials in this field are of strains, and a species contains thousands of them.

What certification it holds, checked at the issuer’s own register
A badge on a bottle is a claim like any other. Every row below was checked — or not checked — at the certifier’s own public register, never at the badge. Across the frozen founding cohort, 2 of 27 products hold a certification we could confirm at the issuer — a founding-cohort figure, not a count over every teardown on this site.
| Programme | Status at the issuer | Checked |
|---|---|---|
| GMP Compliant Third-Party Verified | Brand-asserted, unverified | 31 July 2026 |
| ePV (ePedigree Verification) | Brand-asserted, unverified | 31 July 2026 |
| Per-lot certificate of analysis published on the product page | Brand-asserted, unverified | 31 July 2026 |
GMP Compliant Third-Party Verified
The badge is displayed, but the register could not be reached to confirm it. We call this unverified, not false.
Identical to the brand's other audited SKU: the seal names no certifying body, so there is no register to query and no certificate number to check. Brand-asserted and unverifiable by construction. DRS-307 adds "All XYMOGEN® Formulas Meet or Exceed cGMP Quality Standards" as a footer self-assertion.
ePV (ePedigree Verification)
The badge is displayed, but the register could not be reached to confirm it. We call this unverified, not false.
Xymogen's own in-house programme, not a third-party mark. Recorded so it is not mistaken for one.
Per-lot certificate of analysis published on the product page
The badge is displayed, but the register could not be reached to confirm it. We call this unverified, not false.
A genuine plus. The product page links a lot-specific certificate of analysis PDF. Self-issued and not a third-party register — and publishing a lot-linked COA on the product page is more than almost anyone else in this category does.
How it differs from the same brand’s women’s version
Across the fourteen same-brand men’s-versus-women’s label diffs run inside the frozen founding cohort, zero men’s or default formulas contain a probiotic strain, identified by designator, that was selected on male-specific evidence. In eight of the fourteen the sex-specific differentiator is a botanical or a mineral, and in five of the fourteen the women’s SKU is better-specified, cheaper, or both — “better-specified” meaning the panel that discloses more, never the panel with more in it. The rule behind each of those counts, and all fourteen pairs classified against it , are published in full. Diffs run on teardowns added since sit outside this fourteen, and outside the sentence above.
This brand sells no women’s counterpart to this product, so there is no diff to run.
Every finding on this page, with the record behind it
Finding 1 the-350-billion-headline-has-no-stated-cfu-basis
The only basis footnote on this label reads "Formulated with 650 billion CFU‡ at time of manufacture" — attached to a number that is not the product name, not the front of the box, and not what a serving delivers. The 350 billion per stick pack carries no basis at all. Disclosing the overage is unusually honest; the number a buyer actually relies on is still unanchored in time.

What we could not verify
Every gap below is published rather than deleted. Most are derived automatically from the empty fields in this page’s own record, so a gap cannot be hidden by leaving a box blank.
- 16 strain designators not looked up
- These designators are printed on the panel and have not been searched. They are unchecked, not empty.
- GMP Compliant Third-Party Verified status
- Identical to the brand's other audited SKU: the seal names no certifying body, so there is no register to query and no certificate number to check. Brand-asserted and unverifiable by construction. DRS-307 adds "All XYMOGEN® Formulas Meet or Exceed cGMP Quality Standards" as a footer self-assertion.
- ePV (ePedigree Verification) status
- Xymogen's own in-house programme, not a third-party mark. Recorded so it is not mistaken for one.
- Per-lot certificate of analysis published on the product page status
- A genuine plus. The product page links a lot-specific certificate of analysis PDF. Self-issued and not a third-party register — and publishing a lot-linked COA on the product page is more than almost anyone else in this category does.
- A stated basis for the 350 billion figure
- The only basis language on the label attaches to a different number — 650 billion at time of manufacture. The 350 billion per serving, which is the product name and the front-of-box claim, has no stated basis. The structure strongly implies a through-shelf-life figure and the label never says so, and this page records at-manufacture because that is the only basis the label actually states.
- Per-designator human-trial adjudication for sixteen of the eighteen strains
- Randomised-trial counts were established only for HN019 (41 RCT-tagged) and HN001 (58 RCT-tagged). La-14 and Bl-04 have human record counts (18 and 27) that were not adjudicated for trial status, and no per-designator query was run against the fourteen strains at 5 billion each. The brand's own reference sheet characterises that long tail as demonstrating "Probiotic Effects in Either In Vitro or In Vivo Research", citing agar assays, dendritic-cell maturation and oxalate degradation — which is not human outcome evidence.
- The certifier behind "GMP Compliant Third-Party Verified"
- No certifying body is named, so there is nothing to query. Unverifiable by construction.
How to check every line of this page yourself
Nothing on this page requires trusting us. Every claim above resolves to a record you can open:
- Open the NIH Dietary Supplement Label Database record linked at the top of this page. It is the label the manufacturer filed, not our transcription of it.
- Compare the CFU line and the suggested-use line against the disclosure table above. If they disagree with us, we are wrong and we want to know.
- Take any strain designator from the panel and run the query printed beside it. The query is published precisely so you can get a different answer than we did.
- Divide the price by the number of days the label’s own dose instructions make the container last. That arithmetic is the whole of the cost-per-day row.
- Search the certifier’s own register for this product, not for the brand. A company can participate in a programme without this product being on its list.
Start with the disclosure, because it is the best in its batch and among the best anywhere in this project.
Eighteen organisms. Eighteen designators. Eighteen per-strain CFU figures. And they sum to exactly 350 billion — 125 + 100 + 5 + 5 + 25 + 20 + 5 + 5 + 15 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5. No hidden remainder, no rounding fudge. The panel also uses post-2020 nomenclature — Lactiplantibacillus, Lacticaseibacillus, Levilactobacillus, Ligilactobacillus — which almost nothing else in this project has bothered to do.
That transparency is what makes the next two facts visible at all.
64% of the 350 billion sits in two strains. La-14 at 125 billion and Bl-04 at 100 billion. Fourteen of the eighteen are at 5 billion each — 70 billion between them, 20% of the total. “Eighteen strains” and “350 billion” are both true, and neither describes a formula that is, in practice, two strains plus a long tail.
And the deepest evidence carries the smallest share. HN019 (41 randomised-trial-tagged records) and HN001 (58) are the two organisms here with real human trial literature. Together they are 40 billion of 350 — 11%. The two strains carrying two-thirds of the dose have human record counts of 18 and 27, not adjudicated for trial status. The brand’s own reference sheet is candid about the rest, heading that section “Other Strains… Have Demonstrated Probiotic Effects in Either In Vitro or In Vivo Research” and citing agar assays, dendritic-cell maturation and oxalate degradation — while the product page says “18 scientifically studied strains”.
Then the basis, which needs reading in both directions.
“††Formulated with 650 billion CFU‡ at time of manufacture”
That is the only potency-basis language on the label, and it is attached to a number that is not the product name, not the front of the box, and not what a serving delivers. Disclosing a 1.86x manufacturing overage is unusually honest — most brands bury the overage and print the manufacture figure as the headline. The structure strongly implies the 350 billion is a through-shelf-life number. Implication is not a guarantee, and the label never says “at expiration.”
Two practical warnings to close. DSLD files this product under a different name — “ProbioMax 350 DF” — and there is a genuinely different sibling called “ProbioMax Complete DF” at 30 capsules and 45 billion CFU. Match by UPC or you will pull the wrong record. And this is $10.47 a day, roughly seven times the cost per day of the NSF-certified product in the same batch.
