Which Clean Peptide products are tested for endotoxin?

Short answer

28 of the 36 sizes in the certificate library in October 2026 have an endotoxin result on their certificate: all 24 ILS Laboratories lots, measured by USP <85>, GLP-2 Tirz 20 mg and KPV 10 mg from HYTE Research Division, and both bacteriostatic water sizes from Accurate Test Labs. The five sprays, BPC-157 20 mg, GLP-2 Tirz 30 mg and Epithalon 10 mg have none.

KLOW 80 mg, also on sale, shows its HYTE Research Division certificate on its product page but has no lot page yet, so it is not counted here.

Read from the live lot pages on 30 October 2026. The KPV figure is read from the certificate image; its lot page does not list it yet.

ILS Laboratories reports endotoxin as a measured value in EU/mL with no pass or fail line. HYTE Research Division and Accurate Test Labs report theirs against a limit: 0.5 EU/mL on the GLP-2 Tirz 20 mg and KPV certificates, and 350 EU/mL on the bacteriostatic water report.

A size with no endotoxin result was not tested for it on its current certificate. That is a statement about the paperwork, not about the material.

Where to verify

Follow-up questions

What is the highest endotoxin figure among the ILS lots?

0.134 EU/mL, on the BPC-157 10 mg lot ACE-1090357. Three ILS lots read NMT 0.05 EU/mL, the lowest form of the result.
