XLR8 review: what PepAssess found

As of November 11, 2026, XLR8 has a PepAssess Evidence Score of 15/100 (limited evidence). It publishes 1 lab report and names Not established as its testing lab; none of its reports is confirmed in a lab's own records yet. It publishes its company name (XLR8 Peptides), but no street address. PepAssess didn't find card payments listed on its site. Discount code PEPASSESS gives 20% off. Customers have left 58 reviews on its own site — shown for context, never scored.

What the Evidence Score means

It adds up points for what we could verify about XLR8: 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.
