Reviews on Trustpilot ↗Shown for context — reviews never change the Evidence Score.

Lab reports: this vendor uses a batch/lot lookup — you enter the lot number from your vial to see its report. That's lot-specific, but no reports are visible before you buy, so recency and lab verification can't be checked here.

What the Evidence Score means

It adds up points for what we could verify about Synthesis Peptides: lab reports we matched to the issuing lab's own public record (the biggest part), how often it tests, what the reports cover, contact details, policies, card payments and how long the site has existed. Each card below shows exactly which checks it passed. A higher score means more you can verify yourself; it is not a safety rating, and ads or affiliate deals never change it. Full method ›
