GGPeps (GYC) tirzepatide — PeptideMeter grade A, 98.7% purity

Seeing a lot of confusion about PeptideMeter Analytics' vendor rating system, so let me break it down clearly. PeptideMeter uses a letter grade system (A through E) to rate vendors based on aggregated test data. Here's how it works: Grade A — Excellent (95%+ purity, accurate dosing, sterility pass) - Vendor consistently delivers pharmaceutical-grade product - Multiple passing test results across different batches - Dosing accuracy within ±10% of label claim - Only a handful of vendors achieve this rating Grade B — Good (90-95% purity, minor dosing variance) - Reliable vendor with generally good quality - May have occasional batch-to-batch variation - Dosing within ±15% of label claim - Most established vendors fall here Grade C — Acceptable (85-90% purity, moderate issues) - Product is generally what it claims to be but quality is inconsistent - Some batches may be underdosed - "Use with caution" territory Grade D — Poor (75-85% purity, significant issues) - Frequent quality problems - Underdosing common - Not recommended but not outright dangerous Grade E — Fail (<75% purity, identity failures, contamination) - Vendor has failed critical tests - Products may be mislabeled, severely underdosed, or contaminated - Avoid at all costs These grades are dynamic — they update as new test data comes in. A vendor with a B rating can move to A with more positive results, or drop to C with bad ones. 📊
