Tesamorelin
Is Clean Peptide’s Tesamorelin tested for endotoxin?
Short answer
Yes, both sizes. ILS Laboratories' certificates for Clean Peptide's Tesamorelin report endotoxin at 0.101 EU/mL for the 5 mg lot ACE-3023756 and NMT 0.05 EU/mL for the 10 mg lot ACE-1498675, by the USP <85> method. Both full QC panels also found heavy metals not detected, no growth on sterility and no fentanyl detected.
Contaminant results on the Tesamorelin certificates
| Size | Lot | Analysed | Endotoxin (USP <85>) | Heavy metals (ICP-MS) | Sterility (PCR) | Fentanyl screen |
|---|---|---|---|---|---|---|
| 5 mg | ACE-3023756 | 9 September 2026 | 0.101 EU/mL | Not Detected | No Growth | Not Detected |
| 10 mg | ACE-1498675 | 10 September 2026 | NMT 0.05 EU/mL | Not Detected | No Growth | Not Detected |
Read from the live lot pages on 30 October 2026. Endotoxin is a measured value ("Reported"); the other three are pass results on the certificate.
Endotoxin is measured in endotoxin units per millilitre (EU/mL). ILS Laboratories tests it by the USP <85> kinetic chromogenic method and, on its certificates, reports the value without a pass or fail line, because, in its words, acceptable limits vary by product type and matrix.
Every figure here belongs to the lot named in the table and was read in October 2026. A new lot gets its own certificate and its own lot page.
