The record exists before the lot ships

Synthesised to a written specification

The specification is fixed before the order is placed, and it is the document the result is measured against.

Sampled and submitted

A sample goes to an independent laboratory. People's Peps does not draw the sample and does not engage the laboratory, and the record says so.

Record published at a permanent URL

Result, unit, method, method version, laboratory, scope and dates. The URL is created at release and never moves.

Limits

What we do not test

Missing information is named, not hidden. Every row below is a test we do not run, stated so that nobody has to infer it from a silence.

  1. Sterility

    Not tested

    There is no validated sterile process behind this material, so a sterility claim would have nothing under it.

  2. Bioburden

    Not tested

    Outside the accreditation scope of the laboratory we use.

  3. Residual solvents

    Not tested

    Not part of the release specification at this time.

  4. Heavy metals

    Not tested

    Not part of the release specification at this time.

  5. Stability and expiry

    No programme

    There is no stability data, so no expiry date is printed on any vial or carton.

Measured net content, reported against nominal

Purity alone does not describe how much material is in the vial. A 99% pure vial can still be short. Every released lot reports measured net content against the nominal amount, by its own method.
