Testing & COA requests

Tested for what matters.

Every batch goes to an independent third-party lab for the three standard tests — identity, quantity and purity. Certificates of analysis are emailed upon request and can be verified directly with the testing lab.

Standard testing

The Three Standard Tests

These three tests are run on multiple vials pulled from every batch. Together they answer: is it the right compound, is the full amount there, and how clean is it?

01

Identity

What is it?

  • Checks the vial really contains the compound named on the label.
  • Rules out swaps or cheaper look-alike substitutes.
How it is checkedA lab instrument weighs the molecules to confirm it is exactly the right compound (LC-MS)
02

Quantity

How much is in the vial?

  • Measures how many milligrams of peptide are actually in the vial.
  • A vial can test very pure yet still hold less than the label says — this catches that.
  • Lets you calculate your research measurements accurately.
How it is checkedThe lab measures how many milligrams are really in the vial
03

Purity

How clean is it?

  • Shows how much of the material is the desired peptide versus impurities.
  • A high purity % is useful, but on its own it doesn't tell the whole story — that's why all three tests matter.
How it is checkedA lab instrument separates the sample to measure how much of it is the real peptide (HPLC)

Not part of standard testing

Want more testing? You can do it yourself.

The tests below are not included in our standard testing and do not appear on our COAs. Independent labs typically charge $600+ per vial for them. If you'd like a vial tested for any of these, you're welcome to send it to an independent lab of your choice — that testing is at your own cost.

Tip: email us and we'll tell you which lab tested your batch, so you can compare results.

  • Endotoxin testingBacterial endotoxin (LAL) levels
  • Heavy-metal testingLead, arsenic, mercury, cadmium
  • Fentanyl screeningContaminant screening

How To Verify A COA Yourself

A certificate only means something if you can confirm it independently — don't just trust the PDF. This works for any COA, ours or anyone else's.

Verify it yourself

  1. Find the testing lab's name printed on the certificate — a real COA is issued by an independent third-party lab, not the seller.
  2. Go to that lab's own website (Accumark Labs, Janoshik, Freedom Analytics — whichever is printed) and use its official verify or sample-lookup tool. Never a seller's site, never just a PDF.
  3. Enter the sample code or batch number exactly as printed.
  4. If it's live on the lab's site and every field matches — sample name, code, batch and results — it's real. If not, treat it as unverified.

Red flags of a fake

  • No lab name, letterhead or watermark.
  • No working verify or lookup tool on the lab's own site.
  • A sample code that returns nothing — or a different result.
  • The same chromatogram reused across "different" batches or products.
  • No reviewer or lab-director sign-off.

Our COAs are issued by Accumark Labs. Email us and we'll send the COA for your compound's exact lot, verifiable the same way, directly with the lab.

How we test

Independent, Every Batch

Third-party lab

Every batch goes to an independent lab with no financial stake in the result.

Multiple vials

Samples are pulled from several vials per batch, not a single hand-picked one.

Raw data

Results include the lab's data, not just a pass/fail stamp.

COA on request

Request the certificate for any compound by email, any time.
