The letter comes from fixed score bands, never a curve. The score can change when this vendor's own records change: a new or older certificate, a change in a listed base price (value points), the number of reports on file, or a new Trustpilot rating (the reputation adjustment). Discount codes never change it. The rank compares the same score with the other active vendors PeptideAudits tracks and never changes the letter.
What it takes for A+
- 90+ points (56.3 now)

- Every certificate under 90 days old (17 of 22)
- Independently verifiable lab on every batch (21 of 22)
- Published reports for every product and size sold (25 of 46 products)
- Reported purity ≥ 99.0% on every latest report
