Thank you mods for maintaining this. This list has probably saved thousands of dollars and prevented real harm. I want to add context on a few of these: PeptideKingz — Their website is now down. They were selling primarily through their own site and Reddit promotions. If you see a new vendor pop up with similar branding or COA formatting, please flag it. PeptideElite/PremiumPeptideCo/ResearchChemDirect — This is one serial scammer running the same playbook. Based on domain registration patterns, expect a new iteration within 30-60 days. We need to be vigilant. SynthPure Labs — This is the most serious one. Someone was literally hospitalized. Criminal complaint has been filed.

As someone who just joined this community and is researching compounded semaglutide for the first time, this list is incredibly valuable. It's also terrifying. Question: is there a corresponding "approved" or "vetted" vendor list? I want to make sure I'm buying from somewhere safe but the number of scams here is overwhelming.

Yes! We maintain a vetted vendor list in the wiki (pinned post in the sidebar). Vendors on that list have: 1. Multiple independent lab tests confirming label accuracy (>90% of claim) 2. Consistent positive community feedback over 6+ months 3. Responsive customer service with documented issue resolution 4. Proper cold chain shipping 5. Third-party COAs from recognized labs Please note: even vetted vendors should be periodically tested. Trust but verify. We recommend testing at least your first order from any vendor.

I want to flag something. I've noticed PeptideKingz has started posting on other forums under the name "PeptideKingdom." Same writing style, similar website layout, nearly identical COA templates. I'm 90% sure it's a rebrand. Has anyone ordered from PeptideKingdom? If so, PLEASE send a vial to Janoshik before using it.
