02Label vs. truth

The molecule is clean. The dose is a coin flip.

We check what the label claims against what the assay actually measured. The peptide itself tests near-pure — where it breaks is the fill.

−15%= label claim
one vial in 14 fills short of the label — the underdose you can’t see through the glass
99.4%median purity — the peptide is real

03Graded on evidence

Trust grades A–F, backed by lab certs.

Every vendor carries a letter grade computed from the lab record — never marketing, never vibes.

Tail-gate: one failing batch floors the letter — a vendor with hundreds of certs sits at C behind cleaner, smaller ones. Volume can't buy an A. The worst evidence sets the ceiling.

How we grade the letter
The community record

The certs grade the vial. Buyers report the rest.

The grades above are the lab ledger. This is the other one — what customers post in the vendors' own review channels, relayed here word for word: delivery windows, tracking stalls, which warehouse actually shipped. Testimony, not lab evidence, and labeled as exactly that.

The graveyard

vendors buried by their own lab record.

The record outlives the storefront. When the lab evidence turns, the money and the vendor both disappear. We keep the receipts so the next buyer doesn't inherit the loss.

Have a COA we don't?

Anonymous, no account, no email. We OCR it, parse it, and add it to the corpus that powers vendor pages and trust grades. Real lab COAs always outweigh user submissions in the math — but the long tail only gets covered if customers like you drop one in.
