Frequently asked questions
What we test, how independence actually works, and what a result does — and doesn't — prove.
Trust & independence
Do you test your own products?
No. We don't sell peptides and never will. We only test samples other people submit. That separation is the entire point of the service.
Who can order a test — and does paying for it change the result?
Anyone can order: a buyer checking what they received, or a seller who wants independent proof of their own product. Paying for a test never buys the outcome — we don't sell peptides ourselves, every sample is tested blind, and a published result can't be edited, hidden, or swapped afterward. The result means the same thing no matter who ordered it.
What stops someone faking a QR code or reusing an old COA?
Every QR code resolves to one specific sample and batch on our own domain. A recycled or edited certificate simply won't verify. If a result is ever corrected it becomes a new version with visible history — never a silent edit — and the old version stays reachable and clearly marked.
How testing works
What's the difference between Screen and Release?
Screen confirms what the sample is and how pure it is: LC-MS identity plus RP-HPLC purity, with the chromatogram, spectrum, and raw data. Release adds quantification — net peptide content and a key impurity profile, with optional endotoxin and heavy metals — and is routed to an independent referee lab.
What methods do you run?
LC-MS for identity and RP-HPLC for purity on every test, with net-content and impurity work added on Release. Some compounds need a different method: HGH is run with size-exclusion for dimer and high-molecular-weight species, and NAD+ is a small-molecule assay rather than a peptide purity run. Note the compound when you order and we route it accordingly.
What does a purity number like 99% actually mean — and what doesn't it?
It's the chromatographic purity of the species the method can detect, by peak area — a strong signal that the material is what it claims to be and largely free of related impurities. It does not establish that the material is sterile or safe to use, that every vial from the same source is identical, or that dosing is accurate. Each COA states in plain English what its methods can and cannot show.
Ordering, payment & shipping
How do I order and send my sample?
Place an order, and we give you a shipping address and your blind sample ID. Ship the vial to that address; we photograph and log it the day it arrives, and testing runs under the blind ID — your name never travels with the sample.
How long do results take, and where can I test?
Screen is 5–7 business days from sample receipt and Release is 10–14. China is the live testing region today; the United States, United Kingdom, and EU are on the waitlist and open over time.
Results & verification
What's on the certificate?
The peptide name and claimed amount, LC-MS identity, RP-HPLC purity, observed versus theoretical mass, and — on Release — net content and impurities, plus the methods used, receipt and completion dates, a summary result, and a plain-English note on what the test does and doesn't prove. The raw chromatograms and spectra travel with it, and a QR code links to the permanent verification page.
Can I keep my result private?
Yes. You choose public or private when you order. Private certificates are fully verifiable by anyone with the link but are never listed in the public archive.
What happens if a sample fails — do you publish it?
You get the same full certificate and raw data; a fail is a real result, never withheld from you. Whether it's public is your choice — you pick public or private when you order — so ordering a test never means risking a public fail. When a result is public we show it as it is: we don't quietly filter the archive down to passes, and nothing published can be edited, deleted, or swapped afterward.
Someone showed me a COA — how do I check it's real?
Scan the QR code on the vial, or enter the verification code on our Verify page. A genuine certificate resolves on our domain to the matching sample and batch. If it doesn't verify there, treat it as unverified no matter how it looks.
Scope & limits
Does a passing test mean the peptide is safe to use?
No. A test describes the specific sample we received — its identity, purity, and, on Release, its content and impurities. It does not establish that any material is safe, sterile, or effective, that other vials from the same source are equivalent, or that possession, import, or use is lawful where you are. Nothing here is medical advice.
