Methodology
How Peptide Ad Lab Evaluates Suppliers
Every supplier is scored on the same seven dimensions, and the overall score is calculated from those dimensions — it is never assigned by hand. Where a supplier has not published something, we record it as not confirmed: an information gap is excluded from the calculation rather than scored as a zero, and we never infer a capability a company has not stated.

House weighting: testing and transparency carry the most weight for research and business buyers.
What we look at
Business transparencyCompany information, contact routes and operating detail that a commercial buyer can verify.
Testing / COA availabilityWhether certificates of analysis are published, provided on request, and tied to specific lots.
Wholesale capabilitiesExistence and clarity of a wholesale or bulk program, pricing tiers and account approval.
Manufacturing capabilitiesIn-house synthesis versus distribution, and what is documented about production.
Custom synthesisWhether made-to-order sequences are offered, and what the quoting process looks like.
Private-label availabilityPackaging and labelling programs, and the documented onboarding process.
Geographic fulfillmentWhere the supplier ships from and to, and any stated regional restrictions.
Website / business qualityClarity, completeness and consistency of published commercial information.
Jurisdictions and registrationWhether the supplier states where it operates or ships, and whether its business registration can be verified in a public registry.
Commercial purchasing optionsQuotes, purchase orders, account creation and repeat-order support for business buyers.
Frequently Asked Questions
How does Peptide Ad Lab evaluate suppliers?
Each supplier is assessed against a published set of criteria covering business transparency, testing and documentation, wholesale capabilities, manufacturing capabilities, website experience, commercial purchasing and fulfillment. Assessments use publicly available information: the company's own website, published documentation, and publicly stated programs. Where something cannot be confirmed, it is shown as not confirmed rather than counted against the supplier.
Can suppliers pay to be included?
Suppliers can purchase sponsored visibility, such as a featured placement on a comparison page or a sponsored position on a comparison page. Those placements are always clearly labelled as sponsored. Payment does not create, change or influence a Peptide Ad Lab editorial score. Where a comparison page includes a sponsored position, it carries a visible "Sponsored placement" label, and every other position on the page follows editorial score order.
