Has anyone dealt with ⚠ PeptideDetective exposed: some vendors scoring e grade on basic peptides?

PeptideDetective selects vendors through several channels: 1. Community requests — if enough people ask about a specific vendor, PeptideDetective will prioritize testing them 2. Their own purchasing — PeptideDetective buys product directly from vendors as a regular customer (blind purchase, vendor doesn't know it's for testing) 3. Community-submitted samples — members can send samples from their own orders 4. Vendor opt-in — some vendors actually volunteer for PeptideDetective testing to prove quality (these are marked as "vendor-submitted" vs "blind purchase") The blind purchases (#2) are the most valuable because the vendor had zero knowledge that product would be tested. It's a true random sample of what a regular customer would receive. Vendor-submitted samples (#4) are noted separately in the database because, as we've discussed in the Janoshik threads, vendor-submitted samples can be cherry-picked.

Important context: PeptideDetective's rating system is relatively new — they launched in 2025 and have been building their database since then. They don't have as much historical data as Janoshik, but they're growing fast. Current database size (approx): - ~40 vendors rated - ~200+ individual test results - Focus primarily on GLP-1 peptides (semaglutide, tirzepatide, retatrutide) Distribution of current ratings: - Grade A: ~5 vendors - Grade B: ~12 vendors - Grade C: ~10 vendors - Grade D: ~8 vendors - Grade E: ~5 vendors The fact that only ~12% of tested vendors achieve an A rating tells you something about the current state of the market. Quality is not universal.
