QST
Qingdao Saber Technology
QST's testing coverage stands at 50%, well below the site median of 85%, leaving half its batches undocumented by any lab result. Community testing has filled some of that gap with 10 independent tests submitted, suggesting customers are verifying batches the vendor has not certified. Two batches have been flagged: BPC-157 BP1025Ja01 arrived underweight at 10.57 mg against specification, and Retatrutide R10205Ja01 returned an endotoxin result of 13.930 EU/Vial. Purity across documented batches is consistent, with a median of 99.54%.
Written from the batch and test records on this page. Every certificate counted here was commissioned by the vendor — no independent test has been submitted to the site. Updated 2026-10-18.
