Is there a way to verify if a vendor has been FDA warning-lettered? — 6 month update

OFFICIAL BLACKLISTED VENDOR LIST — Updated March 15, 2026 This is the community-maintained blacklist of vendors confirmed to sell fraudulent, dangerous, or significantly substandard products. Vendors are added based on verified lab testing, documented scams, or pattern of credible complaints. TIER 1 — CONFIRMED SCAM/DANGEROUS (Do Not Purchase Under Any Circumstances): | Vendor | Reason | Evidence | Date Added | |--------|--------|----------|------------| | PeptideKingz | Zero active ingredient in semaglutide | Janoshik HPLC #JAN-2026-03881 | Jun 2026 | | PeptideElite | Exit scam, $8,400+ stolen | 27 confirmed victims | Jun 2026 | | PremiumPeptideCo | Exit scam (same operator as PeptideElite) | Domain analysis, pattern match | Jun 2026 | | ResearchChemDirect | Exit scam (same operator as PeptideElite) | Domain analysis, pattern match | Jun 2026 | | SynthPure Labs | Contaminated product, hospitalization | ER records, member testimony | Feb 2026 | | PurityFirst Peptides | Fake COAs, wrong peptide in vials | Janoshik testing, COA forensics | Jan 2026 | | AlphaResearch Co | BPC-157 sold as semaglutide | Janoshik HPLC | Dec 2025 | | PeptideWarehouse | Endotoxin-positive products | LAL testing | Nov 2025 | TIER 2 — CAUTION (Significant Quality Issues Documented): | Vendor | Reason | Evidence | Date Added | |--------|--------|----------|------------| | PepSource | Systematic under-dosing (43-58% of label) | Multiple Janoshik HPLC reports | Jun 2026 | | BargainPeptides | Inconsistent potency (40-95% range) | 4 Janoshik tests, wide variance | Feb 2026 | | QuickShipRx | Degraded product, poor cold chain | Multiple member reports, 1 test | Jan 2026 | | ValuePeptide Co | Under-dosed tirz (67% of label) | Janoshik HPLC | Dec 2025 | TIER 3 — SOCIAL MEDIA SCAMS (Never Buy From Social Media): All Instagram, TikTok, Facebook, and Telegram peptide sellers should be considered scams until proven otherwise.

We verify all reports before adding to the list.

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.
