How to choose a peptide testing lab

A lab test answers a few plain questions about one vial. Is it the compound on the label? How pure is it? How much is in it? Is it free of endotoxin?

Each question needs its own test. So first check which tests a lab's price includes.

Purity, by HPLC

HPLC splits a sample into its parts. Each part shows up as a peak on a chart. Purity is the main peak's share of all the peaks, as a percent. It tells you how much of the sample is the main compound.

Identity, by mass spec or HPLC

Identity says which compound is in the vial. Mass spec weighs the molecules and compares the mass with the known mass of the compound. Some labs check identity by HPLC instead, by matching the time the peak comes out with a reference sample of the compound. That is an indirect check, because another compound can come out at about the same time. Mass spec checks the molecule itself.

Amount in the vial

The amount is how many milligrams are really in the vial. Labs also call it quantity, net content or potency. Purity and amount are not the same. A vial can be 99% pure and still hold 6 mg when the label says 10 mg.

Endotoxin

Endotoxins come from the outer wall of some bacteria. They can stay in a product after the bacteria are dead. In the body they can cause fever and other reactions. Purity and identity tests do not look for them. It is a separate test, often USP <85>, reported in EU (endotoxin units). Sterility is another separate test: it looks for living bacteria and fungi.

Then compare the rest: the price for your peptide, turnaround, who can order, where you post the vial, and whether the result stays private.

How to read a COA

A COA (certificate of analysis) is the lab's report on one sample. Read it in this order.

• The lab and the sample: the lab's name, a report or sample number, and the dates the sample came in and was tested.
• The method for each result, for example HPLC or LC-MS.
• Identity: a line such as "ID confirmed", with the mass found and the mass expected, or a match to a reference standard.
• Purity as a percent, with the chart (chromatogram). A clean sample shows one tall peak and only small ones next to it.
• Amount in mg per vial. Compare it with the label.
• Endotoxin, if it was tested, in EU per vial or per mg.
• A way to check it: a code, QR code or link to the lab's own site.

A COA is about one sample. Another batch of the same product can test differently.

What to check on a vendor COA

Many sellers show a COA on the product page. Before you rely on it, check these points.

• The batch or lot number on the COA matches the one on your vial.
• The date is recent. An old COA may be for an older batch.
• The lab is named. If the lab has a lookup page, find the report there with its code.
• The compound and the amount match the label. A 10 mg vial should show close to 10 mg.
• It shows identity, not only purity. A purity number alone does not say which compound it is.
• It shows the chart, not only the numbers.

If a point does not match, ask the seller. Or test your own vial: then the result is about the vial in your hand.

What our $99 test measures

Purity, by HPLC

HPLC (high-performance liquid chromatography) pushes the sample through a column. Each substance comes out at its own time and draws a peak. The tall peak is the compound. Purity is its share of all the peaks. Why it matters: at 80% purity, a fifth of the vial is something else.

Identity, by mass spec

Mass spectrometry weighs the molecules. The lab compares the masses it finds with the known mass of the compound on the label. If they match, the report says ID Confirmed. Why it matters: a vial can be pure and still hold the wrong compound. HPLC alone cannot tell.

Amount in the vial (weight)

The lab runs a known amount of the same compound, a reference standard, and compares the peaks. That gives the milligrams in your vial. Here: 10.1 mg against 10 mg on the label, 101%. Why it matters: a vial can be 99% pure and hold half the dose on the label.
