A fentanyl screen on a Peptara Labs certificate is an immunoassay. It flags the substance it targets, while a confirmatory test identifies it. On the certificates we index, the screen is on the Titreon Analytical panel and the published batches read Not Detected. It covers only the substance in its title and says nothing about any product, market or vendor.
Does Peptara Labs screen its peptides for fentanyl?

Peptara Labs says its panel includes a fentanyl immunoassay screen, and on its published batches it reads Not Detected. A screen flags its target, which is narrower than a confirmed identification. The certificates are at peptaralabs.io/coa. A certificate shows what one lot tested as; it does not show a product is safe or approved for use in people.
01 / What does a screen report?
A screen gives a flag for the substance it targets. A confirmatory test gives an identification, which is more specific, though it still relies on matching a known target rather than ruling out every other molecule. They're two different tools, and this line is the first kind.
A screen covers what's in its title and says nothing about substances it doesn't target. We describe the type of test and stop. We name no product, market or vendor as a risk, either way.
What else is on the Peptara Labs certificate panel?
Alongside the fentanyl screen, the Titreon Analytical panel covers identity by retention time match and LC-MS, chromatographic purity against a stated release criterion, net peptide content, sterility, bacterial endotoxin, and a heavy metals screen. Each line answers one question. The full panel is at peptaralabs.io/coa.
02 / Where does a screen stop?
A screen flags its target, a confirmation identifies it, and a screen says nothing about substances it doesn't target.
That's about the method, not any batch or seller. Reading a flag as an identification is the reader's step, not the panel's. The line records a screen result, nothing more.
03 / Where did we read it?
From the Titreon Analytical panel at peptaralabs.io/coa, screen line. We call it a screen because that's how the panel prints it, never a confirmation.
Are Peptara Labs peptides sold as medicines?
No. Peptara Labs describes what it sells as research-grade material with educational information. It says none of it holds marketing approval as a medicine and nothing it publishes is medical advice. We repeat that and turn no measurement into advice. The catalog is at peptaralabs.io/products.
