We were given a lot reference and a certificate number. We were not given the certificate, we have not seen either string on a bottle, and we publish no document we have not read.

The lot reference supplied to this desk for BloodPril is BP-26/BL-4631 and the certificate-of-analysis reference is BP-4631-26-BL. No certificate behind either was supplied, so none appears on this site: this desk publishes no laboratory document it has not been sent. We cannot confirm that either string appears on the product either, because no photograph of the base of the bottle was supplied, and that is where a lot code and a best-before are usually printed. No expiry is published anywhere in what we hold. Credit where it is due: the bottle names a distributor, Blood Pril of Lakeland FL 33804, with a postcode and the telephone number +1 (507) 448-8190, so there is somebody to ask. Twelve seals ship with this product and not one names a certifying body, a certificate number or a laboratory, the GMP mark included. A lot number identifies a production run so it can be traced and recalled; it is not evidence that the contents match the panel. To match a bottle to an order, call +1 (302) 200-3480 with your order ID and the lot.

A lot number identifies a production run. If something goes wrong with that run — a contamination, a mislabelling, an ingredient that was not what the supplier said — it is what makes it possible to find every bottle from that run and recall them. That is a real function, and it is the whole of it.
Here it is worth more than usual, and that deserves saying before the criticism. A recall needs somebody to issue it, and this bottle names that somebody: Blood Pril, Lakeland FL, 33804, on +1 (507) 448-8190. A lot code on a bottle that names nobody is a string with no addressee, and most packs this desk reads do not supply that second half.
What a lot number does not do is test anything. It cannot tell you how much of each of the three blend ingredients is in a capsule, and nor could anything here: the panel declares one line, Proprietary Blend 500 mg, with no weight against any of them. A certificate could confirm the 500 mg total. It could not confirm a split that was never published.
A certificate of analysis would do the rest of that job, and it is the one we do not have. A real one names the laboratory, the date, the method and the result for each thing tested. Without it, a CoA reference is a filing code for a document nobody has shown us.
There is a second absence, and most pages would not admit to it. We have not seen either string on the product. A lot code and a best-before go on the base of the bottle, and no photograph of the base was supplied. So BP-26/BL-4631 is a string in a brief rather than something read off a bottle.
And no expiry is published anywhere. Not on the wrap, not in the brief, not in the listing artwork. The bottle does carry a storage instruction — keep away from heat, light, and humidity — which is not a date. A six-bottle pack is 360 days, so the last bottle is opened roughly ten months after the order.
A reference with no certificate and no photograph behind it is exactly as good as no reference, so we will not print the two codes with a green tick.
A certificate of analysis naming a laboratory, a date, a method and a result, reproduced in full including anything that did not flatter the product. A photograph of the base would go up next to it. Send us either and it is on this page the same week.
A GMP badge — Good Manufacturing Practice — is one of the twelve seals in the artwork. It says a facility documents and controls how it makes things. It is not a test of this bottle and not a test of this batch. It is not an FDA approval either: the FDA does not approve dietary supplements before they are marketed, so no supplement, including this one, is or can be FDA approved.
The bottle itself gets that distinction right. The wrap says this product has been manufactured in an FDA registered facility, which is accurate. Registration means the facility appears on a list the FDA keeps — listed, not inspected, endorsed or approved — and the sentence does not claim otherwise. Many labels overreach on exactly this line.
No certifying body and no certificate number appears for the GMP mark. GMP certification is issued by organisations that keep searchable registers, so without a name or a number the badge cannot be verified by you or by us. Not one of the twelve names a certifying body, a number or a laboratory.
And one point that favours most products does not favour this one. A seal printed on a bottle has been committed to by whoever printed the label; a seal in an advertisement has not. The printed wrap carries no seals at all. It carries something better: a real panel, a caution statement, storage, a named distributor and a correctly asterisked FDA disclaimer.
The only mark here with a policy behind it. 60 days from purchase, with the sales side also asking for at least 30 days of use before a claim. Return shipping is the buyer's cost and tracking is advised; refunds are quoted at 3–5 business days to credit then 5–10 to reach the card. Not stated: whether an opened bottle qualifies, or whether a six-pack can be partly returned.
This one is worded correctly on the bottle, which this desk does not often get to write: manufactured in an FDA registered facility. Registration means the facility appears on a list the FDA keeps. It is not an inspection, an endorsement or approval, and no dietary supplement is FDA approved.
No doctor is named anywhere in the pack as the formulator of this product. A physician's name was supplied with the pack for a different purpose — to be printed as the medical reviewer of these pages, which he has not read. We have not printed it there either.
Good Manufacturing Practice is about how a facility operates, not about what is in this bottle and not a test of this batch. No certifying body and no certificate number is named.
An honest mark, and it matches the bottle: Made in the USA with globally sourced ingredients. It tells you the raw materials are not all American, which is the kind of thing most listings leave a reader to assume the other way.
No certifying body named. Of the four composition seals this is the hardest to check from the panel, since the amino acids are manufactured and the panel does not say by what route.
Naturally suggests the ingredients never contained gluten rather than that the finished capsule was tested. No threshold, no test and no certifying body is named. If you are coeliac, that distinction is the whole question.
Plausible from the panel — nothing in the three other ingredients is a dairy derivative — but no certifying body is named and no test is described.
This one the panel actually supports. The other-ingredients list names hydroxypropyl methylcellulose (capsule), which is cellulose rather than gelatin — the usual reason a capsule is not vegetarian.
Pure names no standard, no contaminant and no laboratory. The brief gives a certificate reference — BP-4631-26-BL against lot BP-26/BL-4631 — and no certificate was supplied to this desk, so we cannot say what it covers.
Natural has no regulatory definition, and it is a strange word for this formula in particular: the three blend ingredients are amino acids supplied as manufactured salts — a malate, an alpha-ketoglutarate dihydrate and a hydrochloride.
The one seal in this set this desk would ask the seller to withdraw. It reads as a promise about an outcome. The only guarantee described anywhere in the pack is a refund window, and the bottle's own disclaimer says the product is not intended to diagnose, treat, cure or prevent any disease.
Five things, and the first four should be asked in writing, by email to [email protected], so that the answer exists as a document rather than as something said on the telephone. +1 (302) 200-3480 if you would rather start there; the bottle's own +1 (507) 448-8190 reaches the distributor in Lakeland, Florida.
Ask for the certificate of analysis for lot BP-26/BL-4631, by its reference BP-4631-26-BL. Ask for the document itself rather than confirmation that one exists, and ask what it covers: identity, potency, heavy metals, microbials.
Ask for the individual weights of the three blend ingredients. This is the question a batch reference cannot answer. The panel prints one total, 500 mg, and the order of predominance gives ceilings of at most 500, 250 and 167 mg. The pooled trials behind the two amino acids used 3 to 9 g and 4 to 24 g a day.
Ask for the expiry or best-before, and for the lot, before the parcel ships. Neither is published anywhere in what we hold.
Ask what the GMP seal refers to, by name and number. With an issuer and a number the mark becomes checkable; without them it is a drawing. The same applies to Guaranteed pure, Non-GMO and the gluten, dairy and vegetarian marks. Of those, vegetarian is the one the panel already supports, because the capsule shell is cellulose rather than gelatin.
Then, when the bottle arrives: photograph the base. That is the one thing you can do that we could not. Photograph the lot code and any best-before, check whether the lot matches BP-26/BL-4631, and check the safety seal. If the bottle says something different from this site, the bottle is right and we are out of date: write to [email protected] and we will correct the page.
It carries the order ID, which matches a bottle to a purchase, and the purchase date the 60-day refund window runs from. Two different jobs, one email.
Because a lot number and a certificate reference look like evidence, and a reader who sees them deserves to know what sits behind them. Here the honest answer is a pair of reference strings and no laboratory document.
A laboratory name and address. A date. A sample identifier tying the document to a specific batch. A list of what was tested for. The method used for each test. The result of each test, with units. And a signature or an authorising name.
None of those exists in anything we were given for this product. What we have is a reference string of the shape a certificate number takes, BP-4631-26-BL, handed over in a brief with no laboratory, no date, no method and no result attached to it. There is also a lot number, BP-26/BL-4631, which is a production reference and a genuinely useful thing to publish — but a lot number is not a test.
So this page prints the strings and says what they are. The alternative — putting them under a heading like Lab Verified — would convert an absence of evidence into the appearance of it, which is the commonest dishonesty in this category.
It matters more here than the rest of this good label suggests. The panel publishes a 500 mg total and no individual weight, so on the three weights a certificate would be the only opinion rather than a second one. If one is ever published, this page will carry it, with the laboratory named.
A reference is given — BP-4631-26-BL, against lot BP-26/BL-4631 — and no certificate was supplied to this desk. Ask the order desk for it in writing.
Nothing supplied says so. A GMP seal is not a third-party test of a batch, and a certificate reference without a certificate is not a result.
You do not, and neither do we. Ask for the certificate of analysis for lot BP-26/BL-4631, in writing, and ask what it covers.
Not in anything supplied to this desk. The brief says the lot and best-before are on the base of the bottle when the bottle shows them; no photograph of the base was supplied. Check it when the box arrives — the six-pack is about a year of product.
Good Manufacturing Practice describes how a facility operates, not what is in this bottle and not whether this batch was tested. No certifying body and no certificate number is named.
One bottle is 60 capsules, which at one a day is 60 days — exactly the length of the refund window. No single bottle is sold, so the smallest commitment is two bottles: $158, $1.32 a day, and 120 days of a product whose three individual amounts are not printed.
The struck-through figures are $358, $537 and $1,074 — which is $179 multiplied by two, three and six. A crossed-out price is a claim about what something used to sell for, and no date is given on which this product sold at $179 a bottle. We print the struck figures because they are on the offer, and this note beside them because they are arithmetic rather than history. · window runs from purchase · no subscription · not for under 18, pregnancy or nursingWritten and fact-checked by The Bloodprildaily Editorial Desk, last updated October 12, 2026.
