Every Blueprint product page carries the same promise: third party tested, with the test results published. That promise is only worth something if you can read the documents behind it. A certificate of analysis, or COA, is a lab report, and like any report it can show passes, near misses, and lines that need a second look. This article teaches you to read one in about two minutes, then reads three real Blueprint reports with you: a batch COA for Longevity Mix, an independent Labdoor report on Essential Capsules, and the uncomfortable one Blueprint published in 2024 when several numbers came back wrong.
This is a documents breakdown, not a review. Everything below comes from published lab reports and Blueprint’s own COA library. No product was tested for this article.
The short version: Blueprint publishes a batch COA for its products, produced by an accredited outside lab, and anyone can read them in the COA library on its store. The reports list claimed versus found amounts for the actives, plus heavy metal, microbial, and pesticide panels. Read properly, they show formulas that mostly land at or above label claims, one famous failure from 2024 that the company published itself, and one independent Labdoor pass on the current Essential Capsules. Testing proves what is in the bottle and whether it is clean. It does not prove the ingredients extend anyone’s life.

The Biggest Trap: Published Does Not Mean Passed
Most readers treat a published COA as a badge. It is not. It is a report, and reports can contain bad news. Blueprint learned this in public in 2024, when a spec sheet it released for an early run of its Essential capsules showed vitamin B12 and biotin not detected at all, spermidine far under its target, and several other actives far over theirs. The company published the sheet anyway, and supplement site PricePlow wrote it up under a headline about the product testing out of spec.
The reason this matters is the state of the wider industry. A 2023 analysis published in JAMA Network Open bought 57 sports supplements online and tested them. About 89 percent did not accurately declare their ingredient amounts, 40 percent contained no detectable amount of at least one labeled ingredient, and 12 percent contained an ingredient the FDA prohibits. Against that background, a brand publishing its lab reports is genuinely unusual. But the value sits in the numbers, not in the existence of a PDF. The rest of this article is about reading the numbers.
What Blueprint Actually Publishes
Blueprint keeps a COA library on its store, with batch reports across the product line. The batch COAs for the supplements are produced by Certified Group, a testing lab in Tustin, California, accredited to the ISO 17025 standard. Each report names the product, the lot, the report date, and the results panel by panel: potency for the headline actives, heavy metals, microbial counts, and a pesticide screen.
Two layers are worth separating. The batch COAs are commissioned by Blueprint and published by Blueprint, which is the standard industry arrangement, made stronger here by the fact that the reports are public at all. The second layer is fully independent testing, where an outside company buys the product and publishes its own report. Essential Capsules has one of those, from Labdoor, and it is the most instructive document in this article.
You can find the dose side of these formulas in my label breakdowns of Blueprint Longevity Mix Ingredients and Blueprint Essential Capsules Ingredients. The COAs answer the next question: do the bottles match the labels?
How to Read a COA: Five Checks
1. Match the report to the product and lot. A COA covers one batch, not a product forever. Check the product name, the lot number, and the report date before trusting anything else on the page. A glowing report from an old lot tells you about that lot.
2. Find claimed versus found. The heart of the report is two columns: what the label claims and what the lab measured. Found amounts above the claim are normal and usually deliberate, because a dose has to survive shipping, storage, and time on a shelf and still meet its label claim at expiry.
3. Know the difference between the label claim and the lab spec. Reports also print a spec, the pass range the lab tests against. A found amount can sit below the label claim and still pass, if it lands inside the spec. That gap surprises people the first time they see it, and one of the readings below turns on it.
4. Read the purity panels. Heavy metals are reported in parts per million, and the numbers should be tiny fractions. Microbial lines should read absent for the named pathogens, with yeast and mold counts far below their limits. Some lines are marked Report Only, which means the lab measured and printed the value without a pass or fail line. Report Only is not a failure. It is the lab handing you the number and letting you judge it.
5. Check who ran the test. A batch COA commissioned by the brand from an accredited lab is good. A report from an independent tester that bought the product itself is stronger, because the brand did not choose the sample. Note which kind you are reading.
Reading One: The Longevity Mix Batch COA
Blueprint’s published batch report for Longevity Mix, report 25-062237 dated March 27, 2025, covers lot HI25-027-01. Here is the potency panel read against the label.
| Ingredient | Label claim | Lab found | Reading |
|---|---|---|---|
| Taurine | 1,500 mg | 1,556.5 mg | Above claim |
| Glycine | 1,200 mg | 1,432.2 mg | Above claim |
| Glutathione | 250 mg | 354.0 mg | Above claim |
| Hyaluronic acid | 120 mg | 123.2 mg | Above claim |
| Vitamin C | 250 mg | 250.6 mg | At claim |
| Creatine | 2,500 mg | 2,260.1 mg | Below claim, inside spec |
Five of the six headline actives measured at or above their label claims. Creatine is the teaching case from check three: the lab found 2,260 mg against a 2,500 mg label claim, but the spec floor on the report was 2,197.96 mg, so the batch passed its specification. Whether you find that reassuring or too generous is exactly the judgment a published COA lets you make for yourself.
The purity panels are quiet, which is what you want. The named pathogens, E. coli, Salmonella, and Staphylococcus aureus, all read absent. Yeast and mold counts came in under 10 per gram against a limit of 1,000. The pesticide screen was completed and glyphosate was not detected. The heavy metal lines are marked Report Only and print trace values: arsenic 0.046, cadmium 0.009, lead 0.019, and mercury 0.002 parts per million.
Reading Two: The Independent Labdoor Report on Essential Capsules
Labdoor, an independent testing company, bought and tested Essential Capsules lot HI26-005-03, with testing run in January and February of 2026 and the lot expiring in January 2028. Its published certificate of analysis marks the product as passed for both accuracy and purity, and prints claimed versus found for every active.
| Ingredient | Label claim | Lab found | Reading |
|---|---|---|---|
| Nicotinamide riboside | 300 mg | 322.5 mg | Above claim |
| Fisetin | 100 mg | 110.6 mg | Above claim |
| Luteolin | 100 mg | 112.8 mg | Above claim |
| Ubiquinol CoQ10 | 50 mg | 54.4 mg | Above claim |
| Spermidine | 10 mg | 10.2 mg | At claim |
| Glucoraphanin | 20 mg | 19.2 mg | Just under claim |
Twenty three of the twenty four measured lines came back at or above claim. The one exception, glucoraphanin at 19.2 mg against a 20 mg claim, is the kind of near miss that makes a report believable: a document where every single line lands perfectly would tell you less. This report is also the strongest single piece of testing evidence in the Blueprint line, because Blueprint did not pick the sample. I printed the full label behind these numbers in Blueprint Essential Capsules Ingredients.
The Report From 2024, When the Numbers Were Bad
The most important document in Blueprint’s library might be the one that embarrassed it. In 2024 the company released a spec sheet for an early run of its Essential capsules, and PricePlow’s write up of that sheet lists the damage plainly. Vitamin B12 and biotin were not detected. Spermidine measured about 73 percent under its specification. Vitamin B1 and folate were also far under. Several other actives ran far over spec, including selenium and vitamin E. The heavy metal panel, notably, was comfortably within limits even on that sheet.
Two lessons survive that episode. The first is about blending: packing microgram and milligram ingredients into one capsule is genuinely hard to do evenly, and the sheet shows what a blending failure looks like in print. The second is about the library itself. A COA page that only ever shows good news is marketing. Blueprint published a bad one, took the coverage, and the current formula’s independent Labdoor report two years later shows a product passing on accuracy and purity. Publishing cuts both ways, and that is precisely why the published record is worth more than a tested claim on a product page.
What Testing Cannot Prove
A COA answers two questions: is the labeled ingredient present in roughly the labeled amount, and is the product free of the contaminants the lab screened for. It answers nothing about whether the ingredient improves health, slows aging, or is worth its price. Those are evidence questions about studies on the compounds themselves, and no lab report on a bottle settles them.
Keep the same discipline with the passes in this article. The Labdoor pass means the current Essential Capsules match their label and screened clean. It does not certify the longevity claims, and neither does any batch COA in the library. What the documents do give you is the thing the JAMA study found most of the industry cannot: a label you can verify.
Before You Order: Run the Two Minute Check
If you are about to buy any Blueprint product, the check takes about two minutes. Open the COA library, find the product, open its most recent report, and run the five checks from earlier in this article: match the lot, compare claimed versus found, note the specs, scan the purity panels, and see who ran the test. Do the same for any supplement brand, and notice how many of them give you nothing to open.

What to Look For on Any Supplement COA
- A named lab and a report date. Anonymous summaries and undated PDFs are not evidence.
- The lot number on the report matching the lot on your bottle.
- Claimed versus found printed side by side for the actives you are paying for.
- Specs printed next to results, so you can see the pass range rather than a bare pass stamp.
- Purity panels with numbers, not adjectives. Trace values in parts per million tell you more than the word pure.
- At least one test the brand did not commission, where one exists. Independent reports are rarer and carry more weight.
Frequently Asked Questions
Is Blueprint third party tested?
Yes. Blueprint commissions batch testing from an accredited outside lab and publishes the reports in its COA library, covering potency, heavy metals, microbial counts, and pesticide screening. Separately, Labdoor has independently tested Essential Capsules and published its own report, which is the stronger form of evidence because the brand did not supply the sample.
Where can I find the Blueprint COA for a product?
In the COA library on the Blueprint store, which collects the batch reports across the product line. Product pages also state that the third party test results are published. Match the report’s lot number and date to the product you are buying, since each report covers one batch.
What does claimed versus found mean on a COA?
Claimed is the amount the label promises. Found is the amount the lab measured in the tested batch. Found amounts usually run somewhat above claim, because manufacturers add overage so the product still meets its label at expiry. A found amount far below claim, or an ingredient not detected at all, is the red flag the columns exist to catch.
Did a Blueprint product ever fail a test?
A spec sheet Blueprint released in 2024 for an early run of its Essential capsules showed serious misses, including vitamin B12 and biotin not detected and spermidine far under specification, and the company published it anyway. The current Essential Capsules formula later passed an independent Labdoor test for accuracy and purity in early 2026.
Does a passed COA mean a supplement works?
No. A COA verifies contents and purity for one batch. It shows the bottle matches its label and screened clean for the contaminants tested. Whether an ingredient produces a health benefit is a separate question about clinical evidence, and no COA answers it.
The Bottom Line
Blueprint’s testing record, read whole, is better than a claim and more interesting than a badge. The batch COAs show formulas landing at or above their labels, with one creatine line that teaches you how specs work. The independent Labdoor report shows the current Essential Capsules passing with a single near miss. And the 2024 sheet shows the company publishing numbers that hurt, which is what makes the good numbers believable. Most supplement brands give you none of this to read.
