## Interpretation notes

- Price order and best-vendor quality order answer different questions.
- Affiliate status and coupon size do not increase a PeptidePrices quality rating.
- Normalized price is a mathematical comparison and may differ from package or final checkout cost.
- A public COA is useful only when the exact compound, form, strength, lot, date, laboratory, method, and result match.
- Unknown or unavailable evidence remains unknown; it is not treated as a negative result.
- Research pages separate human, preclinical, regulatory, product-quality, and commercial evidence.
