Two tests · person vs vial

A certificate a seller hands you is not evidence

A PDF can be edited in a browser in about a minute. A purity figure, a batch number, a laboratory logo and a signature are all just pixels in a file that arrived from the person who wants your money. None of it is evidence of anything until you have looked it up on the laboratory's own site yourself.
That single habit is the most useful thing on this page. Everything below exists to support it: which labs publish a check you can run, what each one charges, and what an accreditation badge (a stamp from an outside body) does and does not cover. The test papers this archive has actually opened are in the certificate search. A row there means we could open the file. It does not mean anyone tested the product blind. Labs that appear on seller reports, and which shops published those names, are on the prices labs page. That list is not a quality ranking and it carries no purity score. Blood tests a person orders for themselves are on bloodwork partners, a different job from reading a peptide certificate. Every figure here was read from the laboratory's own site, or from the accreditation body's own registry, on 14 September 2026.

Vial

Do not mix up a blood test with a vial certificate. They answer different questions.

The check, in three steps

  1. 01

    Find the verification field

    A real certificate has something you can type into the lab's own site: a task number and key, a sample (accession) number, a search code, or a QR code. If there is nothing like that anywhere on the document, stop. There is nothing to check.

  2. 02

    Go to the laboratory yourself

    Type the lab's web address into the bar yourself. Do not use the QR code and do not click the link in the seller's email, because both can point anywhere. A fake copy of a lab's check page is cheaper to build than a real test.

  3. 03

    Match the details, not just the pass

    The compound, the batch or accession number, the date and the amount all have to match the vial in your hand. A genuine certificate for a different batch is the oldest trick in this market.

A laboratory that issues certificates with no public verification is not doing anything wrong. It is serving a business client who does not need one. It does mean that a certificate from that laboratory, forwarded to you by a seller, cannot be checked by you, and should carry exactly as much weight as the seller's own word.

What an ISO 17025 badge actually covers

Accreditation is a stamp from an outside body saying a lab runs certain tests properly. It is given for named tests on named materials, not to a lab as a whole. A lab can be truly accredited while the test you are buying sits outside that list. The list, called the scope document, is public, and almost nobody opens it.

Worked example, checked in the registry

Vanguard Laboratory holds A2LA certificate 6377.01 to ISO/IEC 17025:2017, valid to 30 September 2027. That is real and it is verifiable in A2LA's own directory. We opened the three page scope document. It lists germ testing on food by AOAC methods, trace metals by ICP-MS, leftover solvents, and preservatives, on food, medicines, water, sewage and sewage sludge.

There is no peptide purity or identity test (HPLC) anywhere on it. The accreditation covers the heavy metal and leftover solvent tests inside their larger panels, which is worth having. It does not cover the purity test most people are buying.

This is not an accusation. The laboratory does not claim the scope covers peptides. It is the market that reads an accreditation badge as though it blesses every test on the price list. Check the scope, not the logo.

Of the 6 labs below, 2 hold an ISO/IEC 17025 accreditation from a named body with a certificate number. For one of those we opened the scope and it does not cover peptide purity. For the other we could not get the scope, and this page says so instead of guessing.

The labs

3 of the 6 publish a price list. The rest quote on request, and two of them are set up for companies rather than for a person with one vial.

What the accreditation actually covers

Food microbiology by AOAC methods, trace elements by ICP-MS using EPA 200.8 modified, residual solvent analysis, and parabens and organic acid preservatives. Matrices are food, pharmaceuticals, environmental samples, drinking, surface and waste water, sewage and biosolids.

Peptide purity and identity testing (HPLC) are not on this list.

  • The only lab here that checks for fentanyl. Of all the things that could get into a vial, fentanyl is the most likely to kill somebody.
  • The accreditation is real, but it does not cover peptide purity. It does cover the heavy metals and leftover solvent tests inside the Gold and Elite panels. That is worth something.
  • You pay by invoice after the sample arrives. They hold the report until the bill is paid.

  • By far the most used lab in this market. Sellers post its certificates more often than any other lab's.
  • The public gallery is a sales tool, not a fair sample of the market. A seller posts a result when it passes.
  • Reports in the public gallery are pictures, so a computer cannot read the numbers.
  • The main site has bot blocking, so pages sometimes will not load.

Freedom Diagnostics

Franklin, Tennessee, United States

No accreditation claimed

What they run

  • HPLC for purity and LC-MS for identity, issued together on every certificate

Can you check a certificate

You can look up a certificate by its search code, its accession number, or the exact company name printed on it. The lab says more than 40,000 certificates can be found this way. It only helps if you already have the code. It is not a list you can browse.

Published price

No price list published. Ask before shipping anything.

Turnaround

Two to four days on average, as the lab states it

  • Here, purity and identity are always tested together. That matters. A purity number with no identity check only tells you a vial is 99 percent pure something.
  • There is no public price list. Ask before you ship.

  • A lab that does paid testing for food, drug, cosmetic and supplement companies. It is not a peptide testing service for the public. It publishes no peptide price list and no way to send in a peptide.
  • It is listed here because sellers in this market name it often, and because the accreditation is real. The real question is whether that accreditation covers a peptide purity test. We could not open the scope document to find out.

The lab claims this certificate number, and more than one independent source records it. We could not get the scope document on 14 September 2026, so we cannot say what it covers.

Checking a source somebody else already tested

Four places collect results. The question that separates them is not how many tests they hold. It is who decided which tests appear.

A seller publishes a certificate when it passes. A site built from seller-published certificates is therefore a gallery of successes, and a pass rate computed from one is flattering and false. A site that buys its own samples has no such problem, and its numbers look worse because they are closer to true.

FinnrickSamples chosen by the tester

Ranks sellers for each compound. It shows dollars per milligram and a rating based on purity and on how close the vial came to the amount on the label.

Finnrick gets the samples itself and sends them to outside labs. It posts the results whether they pass or fail. No seller gets to decide what shows up.

9,997 tests as of 3 September 2026.carries prices

To pass, a vial needs 99.5 percent purity and a dose within 35 percent of the label. That is stricter than most. So their numbers look harsh next to sites built on seller certificates. That is the point of them.

PeptigritySamples chosen by the seller

Scores shops using user reviews and lab certificates. It also tracks the price per milligram from shops' public web pages.

The certificates come from the shops' own pages and channels. Peptigrity says so itself. Shops choose which certificates to post, so the tests only show the batches a shop chose to make public.

13,195 lab tests across 631 shops as of 14 September 2026.carries prices

A pass rate built from certificates the sellers chose to post is just a wall of wins. The price tracking does not have that problem. A price on a shop page is a plain fact anyone can see.

Purity on its own does not tell you much

Identity, always alongside purity

A purity figure with no identity check tells you a vial is 99 percent pure something. One test (HPLC) gives the purity. Another (mass spectrometry) confirms it is the right molecule. One lab here puts both on every certificate and never one without the other.

Quantity against the label

Underfilling is the commonest way to cheat, and it is invisible to a purity test. A vial can be 99.6 percent pure and hold two thirds of what the label claims.

Germs and bacterial toxins, if it is going under the skin

Neither a germ test (sterility) nor a bacterial toxin test (endotoxins) is part of a purity panel anywhere on this page, unless you pay for it separately. One lab says outright that its purity testing does not cover sterility, endotoxins, heavy metals or pH. A clean purity number says nothing about whether a vial is free of germs.

Contaminants nobody advertises

Heavy metals, leftover solvents, and fentanyl. One lab on this page screens for fentanyl, which is the contaminant most likely to kill somebody, and it costs $50 as an add-on.

What this page is not

We have not paid for a test from any lab here and we hold no certificate of our own, so nothing on this page is a first-hand measurement. We have no relationship with any of them, take nothing from any of them, and the order they appear in is not a ranking. Where a laboratory publishes no price or no turnaround, this page leaves it blank instead of filling it in from somewhere else.

Nothing here is a recommendation to buy or use any compound. Laboratories named on seller certificates · How this site works.
