What we check

Each one is shown in the lab report that comes with every batch.

Identity
We confirm it's the right peptide.
Mass spectrometry checks that the peptide's weight matches what it should be (within a tiny margin). The full reading is in the lab report so you can check the data yourself.
Purity
99% pure or higher, with the test data on the report.
We use HPLC (a standard purity test) with UV detection. Anything under 99% is rejected — it never reaches you. The full test data, settings, and conditions are in every lab report.
Potency
We measure how much peptide is in the vial.
Where it applies, we measure peptide content against a known reference and list the result as a percentage of total weight. The method is in the report so your team can repeat it.
Stability
Cold-pack shipping and clear storage instructions.
Freeze-dried vials ship with cold packs when needed. Each product page lists the right storage temperature and how long the peptide stays good. We ship the oldest stock first — your batch won't be close to expiring.
Consistency
We track how batches compare over time.
Each batch number ties back to one production run. When we re-test older batches, we add the results to the report history so you can see how the peptide holds up.

Frequently asked

Common questions about lab reports, shipping, and research use. Need something else? Contact us.

Are these peptides for human or animal use?
No. Everything we sell is for lab research only. These products are not drugs, supplements, or cosmetics, and are not for people or pets.
Is a lab report included?
Yes. Every batch we ship has a lab report you can read on the Lab Reports page. It shows the purity test, identity confirmation, and how much peptide is in the vial.
Do I need an account to browse?
No. Anyone can look at the catalog and lab reports. You only need an account when you place an order — that way we can send you shipping updates and keep your order history.
How are orders shipped?
Tracked shipping, with cold packs when needed. See the Payment and Shipping page for options and delivery times.
What if a vial arrives damaged or off-spec?
Send us a photo within seven days and we'll replace the batch. No return form. Full details are on the Returns & Refunds page.
How do I get product updates?
Sign up for Research Updates in the footer. We send about one email a month with new batches, restocks, and updated lab reports.
