What the public record says
The most useful source for this profile is the current terms document because it distinguishes the contracting seller from the manufacturer. The public portion of the About page provides a different kind of information: access restrictions and a description of analytical reports. Those records should not be merged into an unsupported claim that the US seller owns a Chinese synthesis facility or that every test applies to every batch. Researchers can instead ask for the identity of the relevant manufacturer, product-specific documentation and the original issuing-laboratory report. This review did not create an account, contact support or inspect a shipment.

Questions for the exact product and lot
- Which contract manufacturer produced the specific material and lot?
- Which batches have endotoxin testing, and what specification does the report use?
- What documents remain unavailable without approved account access?
Questions, answered.
Does Liyu's US seller registration mean its peptides are US-made?
No. Its own terms separately disclose mainland-China contract manufacture. Seller jurisdiction and synthesis origin are distinct.
Does the public page establish endotoxin testing for every batch?
No. The reviewed public wording refers to selected batches. Check the report for the actual lot rather than generalizing.
