Research use only · Every lot tested
One peak. Nothing else.
Research-grade peptides with an outside lab report for every lot, and a code to verify it yourself.

The Viren standard
Five checks. Every lot. No exceptions.
An independent lab runs every test below before a lot goes on sale. We don't grade our own work.
Purity
HPLC shows how much of the sample is the target peptide.
HPLCIdentity
Mass spec confirms the molecule is the one on the label.
Mass specReal amount
We measure the mg in the vial, so the label means something.
Content assayEndotoxin
Screened for endotoxin, because purity alone doesn't catch it.
LAL testA code you can check
Every report has a lot number and the lab's own verification code.
Lab lookupThe catalog
Freeze-dried, sealed, and lot-matched.
Every product is sold for in-vitro laboratory research only.
Don't take our word for it
Check any report in three steps.
STEP 01Find the lot.
The lot number is printed on every vial.
STEP 03Ask the lab.
Enter the verification code on the lab's own website. If it doesn't match, don't trust it.
After you order
Ships fast from the US. Arrives plain.
- Packaging
Plain, sealed packaging with tracking. Nothing on the outside says what's inside.
- Storage
Freeze-dried and stable in transit. For long-term storage, keep at -20°C and away from light.
Questions
Asked by careful buyers.
Yes. Every lot goes to an independent lab before it's listed. We don't grade our own work.
Yes. Each report shows the lot number and the lab's verification code. Enter the code on the lab's website and the original report comes up from their side, not ours.
Both. HPLC measures purity. Mass spec confirms it's the right molecule. A clean sample of the wrong compound would still fail.
We test real mg content on every lot, because a 99% purity score doesn't tell you how much is in the vial.
Yes. Endotoxin is tested separately, since purity testing can't detect it.
Never. One lot gets one report, with its own date and its own code.
Inside the US, in plain packaging with tracking.
No. Every product is for in-vitro laboratory research only. They are not drugs, foods, supplements, or cosmetics.
