Independently Tested

SPB | Retatrutide, last activity 1 month ago

Independent testVendor COA ×2

SPB rarely publishes certificates, making the independent retest here unusual. The independent lab found 99.69% purity at 31.07 mg, compared to the vendor's 99.54% at 32.02 mg—both results are in line with other retatrutide batches, and the batch is receiving more attention than typical for its age. Endotoxin was within the working limit at 5.093 EU/vial.
