The things people ask before their first review — and how to reach us for anything else.
The essentials, in plain English.
A Certificate of Analysis is the lab document stating what a product contains — typically purity (HPLC), identity (mass spectrometry) and sometimes contaminant panels. The problem: anyone can fake a PDF. PepiScreen forensically analyses the certificate — the data, the dates, the lab, the formatting fingerprints — and scores what the evidence actually supports.
No. PepiScreen is 100% independent — we sell evidence reviews, not peptides, and we take no commissions from sales. Even suppliers who sponsor review codes get the identical scoring engine: that independence is exactly why a strong score means something.
The 0–100 score measures how well the paperwork proves the claims — not whether a product is safe. Most research-peptide suppliers currently score 40–60; above 75 is genuinely exceptional. "Weak Evidence" means the documents don't substantiate the claims, not that the product is dangerous.
Optional: tell Pepi what you paid and the review assesses value against typical market ranges for that compound and quantity. Suspiciously cheap is itself a risk signal — and a premium price for weak evidence earns a caution.
No. PepiScreen audits documentation — it never assesses whether any compound is safe or appropriate for you, and it will not give dosing or usage guidance. Decisions about your health belong with a qualified healthcare professional. Regulators including the FDA and TGA have publicly warned about mislabelled peptides sold online.
