The Lot Mark

Lot 121125450.
Three of four.

Under Load, collagen peptides, Type I & III. The missing quarter is identity: nothing on this document tests the powder against a collagen reference, and the protein row is a quantity rather than an identification. The document also has the softest chain of the three we hold — it was run by the company that manufactures the powder — and that sentence is at the top of this page rather than the bottom of it.

The Lot Mark · Under Load · lot 121125450 · our count, on our document
Axis	State	Figure, with its opponent	Margin	Method
Identity	NOT RUN	No identity assay of any kind on this document — no infrared scan, no chromatographic fingerprint, nothing testing the powder against a collagen reference. The ingredient line reads collagen peptides, which is a statement rather than a test. The protein row below is a quantity: it says how much protein is in a serving, not that the protein is collagen.	—	—
Metals	MEASURED	Lead 0.07 mcg per serving against a 0.5 mcg Proposition 65 limit. Mercury, arsenic and cadmium all read below the detectable limit.	7× under	ICP-MS
Microbiology	MEASURED	Total plate count, E. coli, salmonella, yeast and mould — five rows, every one a pass.	No ratio: the document reports verdicts against limits rather than counts	AOAC VIDAS
Potency	MEASURED	Protein 9.8 g against a 9 g specification, in the document’s 10 g serving. A quantitative result, not a pass.	0.8 above the floor	ISO 14891:2002

Chain: Analysed by ViaCore Nutrition, 625 Jensen Road West, El Reno, Oklahoma — the laboratory of the company that manufactures this powder, not an independent one. Signed Austin Snowden, 22 December 2025. No accreditation is claimed on the document and we claim none for it. Three of the four metals read below the method’s detectable limit, which is a floor rather than a quantity.
Arithmetic: 7× and 0.8 are ours: 0.5 ÷ 0.07 rounded down, and 9.8 − 9. Both operands of each are printed above and in the table below. Everything else is transcription.
Limit: This is the lot on the document. It is not the lot in your jar.

Four questions a certificate can answer, counted. The state is a count of rows on a document — whether a result column exists for that axis, with a method printed beside it. The margin is the division or subtraction of two figures printed on the same row, and both operands are above so you can redo it. The token is a count of counts, and the denominator is always printed so it reads as an incompletion rather than an award. Nobody awards this and there is no body that could take it away. What each of those words means, at length.

The part that comes out worst for us

This certificate was run by the company that makes the powder.

ViaCore Nutrition of El Reno, Oklahoma manufactures this collagen, and ViaCore Nutrition analysed it. The document names its laboratory, which is more than any of the four certificates we published until August 2026 did. It does not name an accreditation, and we are not going to imply one for it.

Creatine and Night Work were tested by an independent lab that had nothing to do with making them. The collagen was tested by the company that makes it. That’s a weaker check, and you should hear it from us rather than work it out later.

The mark above does not know any of that. It counts how many axes carry a measured result and nothing else, so a 3 / 4 from an in-house laboratory prints exactly the same as a 3 / 4 from an outside one. That is a limit of the instrument rather than a verdict about this lot, and it is the reason this box sits above the ledger instead of inside it.

What would change it: the same powder, the same lot, assayed by an outside laboratory. That costs a few hundred dollars per product and it is the cheapest upgrade available to this brand. When it happens, the result publishes here in full — including if it disagrees with the figures above, which is the only version of that promise worth making.

The hero product having the softest paperwork is an awkward sentence to write on a page whose job is paperwork. It is also the honest ranking, and it is on the product section too, in the same words: if you are buying one tub this month on documents alone, buy the creatine. Its mark is a four.

The document, published whole

This is the certificate. Nothing on it is cropped, marked or redacted.

Certificate of Analysis for collagen peptides, lot 121125450, issued by ViaCore Nutrition of El Reno, Oklahoma, analysed 12 slash 22 slash 2025 by Austin Snowden. It reports protein at 9.8 grams against a 9 gram specification by method ISO 14891 colon 2002, heavy metals by ICP-MS against Proposition 65 limits, and a microbiological panel, all passing. — **What this document is** — **ViaCore Nutrition**, 625 Jensen Road West, El Reno, Oklahoma — **the company that manufactures this collagen**, testing it in its own laboratory. Lot **121125450** · serving 10 g · analysis 12/22/2025, signed Austin Snowden. **This is the only document TARE holds that names the lot its own tub was filled from.** It reports protein, heavy metals and microbiology with measured results; it reports no identity test, which is why this mark is three rather than four. It names no accreditation and we do not imply one. Reproduced whole and unaltered.

Field by field

Where every line
on this page came from.

One row per field: what it says, where it came from, and how a stranger checks it without taking our word for any of it. Most of these you can check today. Two of them nobody can check yet, and those rows say so rather than reading as though they were the same kind of fact as the others.

Lot code: 121125450, as printed on the certificate header. Two of our three certificates name a lot; this is one of them.Source — the certificate headerCheck it — Not yet, independently. The file is not published — the limits at the foot of this page say why.
Formula and servings: Under Load — collagen peptides, Type I & III, bovine. One ingredient. The tub’s printed serving is 10 g, two scoops, 35 servings, 350 g net. The full panel is on The Monograph.Source — the labelCheck it — Read the tub.
Dates and extent: Analysed 2025-12-22, signed Austin Snowden. Manufactured: Not printed on the document. The document is a quantitative analysis with a heavy-metals page against California Proposition 65 limits and a microbiological block of five rows.Source — the certificate, and absent where the document does not print itCheck it — The transcription, row for row.
The four axis states: Metals, microbiology and potency measured. Identity not run — no infrared scan, no chromatographic fingerprint, nothing testing this powder against a collagen reference. That is 3 / 4.Source — counting rows on the certificateCheck it — The full transcription, row for row. If a row we call measured has no result beside it there, the mark is wrong and we want to be told.
Every figure, with its specification: In the mark above, and in full at the transcription. It is deliberately not re-typed on this page: a second copy of the same figures is a second chance for them to disagree. One number, one place.Source — transcription from the certificateCheck it — /testing#under-load, row for row.
Margin: 7× under on metals, from 0.5 ÷ 0.07 rounded down, and 0.8 above the floor on potency, from 9.8 − 9. Both are ours and both operands of each are printed in the mark above. No ratio is computed on microbiology, and the mark says in words why not: the document reports verdicts there rather than counts.Source — ours — a division and a subtraction, both operands printedCheck it — Redo the division. Ten seconds, no trust required. If it does not come out, we have made an error, and it gets corrected here in public.
Method: ISO 14891:2002 is a published method with a number — anyone can look up what it involves. ICP-MS names a technique rather than a numbered protocol, and AOAC / VIDAS names a body of methods and an instrument platform, so both say what was done without saying to which written procedure.Source — the certificateCheck it — A numbered public method can be looked up by anyone. An internal laboratory code cannot be, by anybody outside that laboratory, and the difference is the whole of what a method column is worth.
Laboratory: ViaCore Nutrition, 625 Jensen Road West, El Reno, Oklahoma — the laboratory of the company that manufactures this powder, not an independent one. No accreditation is claimed on the document and we claim none for it. The account of what that is worth and what it is not is in the box above, at length.Source — the certificateCheck it — The address is printed here and on the document. What cannot be checked by anyone is the thing an accreditation would have established, which is why we say so instead of implying otherwise.
Customer of record: The company that makes the powder ran the assay and issued the document, so the maker and the laboratory are one party here rather than two. That is the whole of the finding, and it is not softened anywhere on this site.Source — the certificateCheck it — The panel at /testing sets it out in the same words.
GMP assessor, standard, expiry, scope: Not known — open with our manufacturer. Until August 2026 this site carried facility attestation letters belonging to our former manufacturer. On the day we changed manufacturer they stopped describing anything we sell, so all four fields came off — assessor, standard, expiry and scope travel together or none of them do. No badge returns until the letter is in hand and someone has read it.Source — nothing; we hold no letter for the current facilityCheck it — Not checkable by anyone, including us. It is on the open list at /testing and it stays there until a document arrives.
Detection and quantitation limits: Not yet transcribed. Three of the four metals read below the method’s detectable limit, which is a floor rather than a quantity — and a floor means nothing until the number under it is printed, so no margin is computed on those three either way.Source — the certificateCheck it — The ledger of what is still being read lists every cell on this site that is a blank rather than a figure.
What is missing on this lot: An identity assay. The ingredient line reads collagen peptides, which is a statement rather than a test, and no row on this document tests the powder against a reference. Also unread here: the Proposition 65 limits for arsenic, cadmium and mercury, and the individual microbiological rows. And nobody bought this tub anonymously off a shelf — the document was supplied to us by the company that made it.Source — the absence of a row, and the absence of a transcription, named separatelyCheck it — Count the rows. An absence is only checkable if somebody prints what is absent.
Whether this is your lot: It is not. TARE is fulfilled by a contract manufacturer and never takes possession of inventory, so nothing connects a published lot to the tub you receive. We do not offer per-lot traceability and we do not claim it. The day that sentence stops being true it is deleted, and not one day sooner.Source — limit 1 at /testingCheck it — The lookup on the directory page is switched off for exactly this reason, and the note beside it says what would switch it on.

The five strings this page uses for something it does not have

NOT RUN — the test was not performed and no row of any kind exists on the document.

NOT PRINTED ON THE DOCUMENT — the document exists and omits this field.

NOT YET TRANSCRIBED — the row is on the document and we have not finished reading it. Ours to fix, listed at /testing, and never filled in from a label in the meantime.

NOT KNOWN — OPEN WITH OUR MANUFACTURER — we have asked and have not been answered.

NOT HELD — we hold no certificate for that lot at all. That is the answer the lookup would return for nearly every code printed on a tub, which is why it is switched off rather than shipped as a control that can only say no.

One thing on this document worth reading twice

The certificate reports against a 10 g serving — the tub’s printed serving. The protocol on this site is 15 g on training days, which is a site instruction rather than a label figure. Read the word “serving” carefully on any document, because two parties rarely mean the same thing by it and every figure in the table inherits whatever it meant. Both figures are run forward to our serving on the panel, with the arithmetic printed, and the measured one is the larger of the two — which is the only direction that arithmetic is allowed to run here.

The limits

What this page
cannot tell you.

Publishing a document is undone by overstating it. Four things this page does not do, written out rather than left for you to notice.

The underlying file is now published, and that changed on 5 September 2026. Certificates in this trade routinely carry a clause requiring the issuer’s written approval before reproduction. We asked. Our manufacturer granted publication in writing on 17 August 2026 — he advised against it, and then said yes — so the document is reproduced whole and unaltered, which is what its own footer requires. The sentence that used to sit here, saying we had not confirmed we may reproduce it, was true when it was written and stopped being true three weeks later. Where that stands across all three documents.
This certificate was run by the company that makes the powder. It is the only one of our three that was, it is our hero product, and the box above says so at length rather than in a footnote. A mark counts what a document measured; it does not weigh who measured it, so the two have to be read together.
This is the lot on the document. It is not the lot in your jar. TARE is fulfilled by a contract manufacturer and never takes possession of inventory, so we cannot connect the lot on a published document to the tub in your hands. We do not offer per-lot traceability and we do not claim it.
A certificate verifies contents. It does not verify effects. Nothing on this page is a claim about what any of this does for anyone. What the research shows, where it is weakest, and the outcomes no trial has shown are on The Monograph.
