The letter comes from a fixed rubric on this vendor's own lab reports, so it only changes when their reports change (or age). The rank compares that score with every other active vendor and never changes the letter.
What it takes for A+
- 90+ points (69 now)
- Endotoxin test on every batch (7 of 16 tested & passed)
- Every COA under 90 days old (9 of 16)
- Independently verifiable lab on every batch
- Purity ≥ 99.0% on every batch
