Highest grade. Lowest real price.

Every vendor we've tested, ranked by Pep Score — 70% quality (pass rate, purity accuracy, label accuracy, transparency) + 30% verified value (real $/mg vs. category median). Formula is published; arithmetic, not opinion.

How ranks work: minimum 2 tested batches to be scored (1 test = Provisional). A verified fail caps a vendor at 49 until a later blind retest passes. Scores decay after 12 months without a retest — passing once buys nothing permanent; every vendor returns to the testing queue on an ongoing cycle. Verified $/mg = what we paid ÷ the mg the lab actually measured — an underdosed “cheap” vendor gets more expensive, honestly. Vendors cannot pay to be tested, ranked, or removed. Vendors at ◆ Verified Elite / ✓ Recommended may license the “Pep Tester Verified” mark — the mark is earned in the lab and can never be purchased. Full formula →
