Panda Peptides is a research peptide supplier based in California. We carry over 40 compounds including semaglutide, tirzepatide, retatrutide, ipamorelin, CJC-1295, and BPC-157. Every batch gets tested at an independent U.S. lab before it ships. We post the Certificate of Analysis (COA) for every product so you can check the purity yourself.We started Panda because we were tired of ordering from vendors who made big promises and couldn't back them up. No test results. Slow shipping. Support that disappears after you pay. We built the company we wished we could buy from.Orders ship within two business days. Every product is 99%+ purity verified. If something isn't right, we fix it.Got a question about a product, your order, or our testing? Email [email protected]. Real people, real answers.

Quality product for my research. I got my reconstitution solution from Lambda Water and it has all been working great for me. I highly recommend!

Customer service at Panda is highly commendable. However, I was disappointed to find no batch numbers on the vials to correlate with the COA. Without a direct line of production linked to the paperwork, a COA is just a isolated result that cannot be assumed to apply to every unnumbered vial. If Panda begins adding corresponding references to their packaging, it would allow for independent quantifiable confirmation testing vs anecdotal reviews.
Response from Panda PeptidesJul 18, 2026
Hi BAE, Thank you for the thoughtful feedback—and for the kind words about our customer service. Your concern is fair. For the products you received, there was only one released batch in circulation at the time, and the QR codes on the vials link to the corresponding product testing pages. Even so, you are right: that is not as clear or independently traceable as printing the batch number directly on each vial. Based directly on your feedback, we have changed our labeling process. Every new batch going forward will have its corresponding batch number printed directly on the vial so it can be matched to the published testing documentation. We already have several independently tested new batches incoming, and they will use the updated labels. We have also published a detailed explanation of how we source, test, release, and document batches—including what representative testing does and does not prove: https://pandapeptides.com/quality-and-testing/ Thank you for holding us to a higher standard. You identified a real gap in our packaging, and your feedback made our process better. — Cory Founder, Panda Peptides

A+ company!!! Placing my order now with this company. I came across a fake page on FB claiming to be Panda with pricing that was too unreal. I actually loaded up $400 of product until I thought I should go straight to the Panda Peptides website. OMG! Two completely different pages and prices. Something not right. I started a chat with both. Two different phone numbers. But, the FB fake Panda admitted they had no company in the U.S. and they shipped direct from China. RED FLAG! They copied everything from the real Panda Peptides site, the branding, the vials, the format. ChatGPT confirmed that Panda Peptides was located in CA and was already a well established and high rated vendor. Minutes later, I received a voice call from Cory, the founder of Panda. He informed me that the FB copy was illegitimate and he does not advertise on FB. We spoke for awhile and I was comforted to know that I was speaking to the real deal. Funny, but when I confronted someone named Ellie from the FB page showing them a screenshot of the website, they stopped texting. Proof they were scammers. Caution: always do your research! Thank you Cory for all the info and standing up to the Chinese scammers. I am placing my first order with you now.
