Our Retatrutide 30 mg was sent blind to Janoshik Analytical, an independent lab, and tested alongside Semaglutide and Tirzepatide. Here is the full report. Check the result yourself with the lab's own verification key.
Every compound comes as a 10-vial kit from a single synthesis lot with one certificate of analysis — consistent material for longer studies, priced well below buying ten single vials.
Ordered several times now. Packaging has been consistent every
order, labels are clean, and everything arrives looking organized
instead of rushed. That consistency is why I keep coming back.
Large order arrived complete with no missing items. Seals looked good, presentation was clean, and everything matched the invoice.

FAQ
01Are your peptides third-party tested?
Yes. Batches are tested by independent third-party laboratories, and the lab and test date are named on each report so you can see exactly where a result came from.
Certificates of Analysis are published on our COA page, and many can be checked on the lab's own site with a verification key.
Testing
02How do I match a COA to my product?
Compare the product name and batch (lot) number on the vial or outer packaging with the matching report on the COA page. A report for one batch shouldn't be treated as the result for a different batch.
Testing
03What does "≥99% purity" mean?
It's the purity result reported for that batch, usually measured by HPLC as the share of the main compound compared with other detected components. Mass spectrometry is often added to confirm identity. The exact figure and method are on each batch COA.
Testing
04Where do you ship, and is shipping free?
We ship to the USA, Canada and the EU from regional warehouses. Orders over $300 ship free to supported destinations, and the final shipping cost is always shown at checkout before you pay.
Orders
05How do I track my order?
Tracking is emailed once your shipment is prepared and the carrier label is created. You can also sign in to My Account › Orders, or use Track Order. Allow a little time for the first carrier scan to appear.
Orders
06Do you offer savings on larger orders?
Yes. Add 3 or more different compounds to your cart and an extra 5% comes off those items automatically, on top of current sale prices. You can also build a bundle, choose 10-vial kits, or ask about wholesale.
Orders
07What does "Research Use Only" mean?
Products are supplied exclusively for laboratory, analytical and scientific research. They are not medicines, foods, supplements or cosmetics, and are not for human or animal use. Buyers must be 21 or older. Read the full Research Use Policy.
Policies
08What is your refund and return policy?
Because research materials need controlled handling, sales are generally final and returns or exchanges aren't accepted. If an order arrives damaged or incorrect, contact us promptly with photos and keep all packaging so it can be reviewed. See the Shipping & Refund Policy.
