⚠ PeptideMeter exposed: some vendors scoring E grade on basic peptides — what worked for you?

Great discussion. A few final notes: - PeptideMeter's ratings are one data source, not the final word. Cross-reference with Janoshik community tests and user experience reports for the fullest picture. - If you disagree with a PeptideMeter rating or have contradictory data, post it here. Healthy debate strengthens the community's knowledge base. - Vendors who earn Grade A aren't "verified" in any official sense — they've simply tested well. Past performance doesn't guarantee future quality. We'll continue to update the Vendor Directory with PeptideMeter grades as they publish new data. Thanks to everyone contributing to this discussion. The more informed the community is, the safer everyone is. 🛡️
