Independent laboratory testing across three facilities

Laboratory testing · Coming soon

One coded sample. Three facilities testing independently. All three reports returned to the client.

  1. 01

    Sample coded

    Each sample will be assigned a code before submission. The client's and source's identity will not be passed to the facilities.

  2. 02

    Tested independently

    Three independent facilities will each test the coded sample without reference to one another's work.

  3. 03

    All three reports returned

    Results will return to PeptideSciences101, and the client will receive all three facility reports — not a summary or a selected result.

When reports differ, those differences will remain visible. No report will be replaced by a selected, blended, or averaged result.

Analytical testing does not establish clinical safety, effectiveness, or suitability for treatment.

Profiles are grouped by what the evidence actually shows — from FDA-approved drugs to compounds with only preclinical data. The two evidence buckets count only profiles whose grade has completed editorial review; the two regulatory buckets cover the whole catalog.

How PeptideSciences101 evaluates evidence

  • Primary sources prioritized

    FDA labels, DailyMed, ClinicalTrials.gov, and PubMed-indexed studies.

  • Human evidence separated

    Clinical trials are separated from animal, in-vitro, and mechanistic evidence.

  • FDA status is visible

    Approved drugs are clearly separated from research-stage peptides.

  • Research-stage content labeled

    Unapproved compounds are not presented as treatments.

  • Review status is shown

    Each profile shows its evidence grade, or says plainly that editorial review is still pending.
