Well, this thread has definitely been enlightening, especially since I just placed an order with them via WhatsApp. I can’t understand why anyone would think it’s a good idea to share a fake COA—talk about an instant way to screw your reputation.
I found PolyPeptide/Zhaobo Biotechnology (PPZB) through the same person others have referenced here (MN on Reddit). After finding this thread this morning, I reached out to him with my concerns, and he replied pretty quickly. I don’t get the impression that he’s shady; in general, his copy/paste message cited multiple sources (kits4less, QSC, PPZB) and provided a lot of helpful details for people new to peptides. I can understand why he wouldn't want to retype all of that information every time someone sent him a message.
Before I placed my order, PPZB sent me a COA from peptidetest.com dated August 2024. I believe it to be legitimate; I emailed info@peptidetest and they directed me to their verification tool to confirm its authenticity:
https://coa.trustpointeanalytics.com, using the verification key. It passed, so that's a positive.
Ultimately, this doesn’t excuse the shady actions of this supplier in providing fake COAs in the past, that is an incredibly shady thing to do. However, it does offer some reassurance that their product is legitimate. Anyhow, if you do proceed with an order, do so with caution. Results attached.
