Tesamorelin
How much Tesamorelin is in a Clean Peptide vial?
Short answer
Slightly more than the label. ILS Laboratories measured 5.21 mg of net peptide in the 5 mg lot ACE-3023756 (104.2% of label) and 10.51mg in the 10 mg lot ACE-1498675 (105.1%), on certificates dated 9 September 2026 and 10 September 2026. Net peptide content is the peptide itself, separate from HPLC purity.
Measured content against the label
| Size | Lot | Laboratory | Analysed | Net peptide content | Share of label |
|---|---|---|---|---|---|
| 5 mg | ACE-3023756 | ILS Laboratories | 9 September 2026 | 5.21 mg | 104.2% |
| 10 mg | ACE-1498675 | ILS Laboratories | 10 September 2026 | 10.51mg | 105.1% |
Read from the live lot pages on 30 October 2026. Share of label is the measured content divided by the labelled size.
Net peptide content and HPLC purity answer different questions. Purity is the share of the main peak among the peptide-related peaks; content is how many milligrams of peptide the lab measured in the vial. The 5 mg lot read 99.40% purity and the 10 mg lot 99.74%, both against a specification of at least 95.0%.
ILS reports content without a pass or fail limit, so the certificate states the amount it measured rather than a tolerance around the label.

Follow-up questions
Was identity confirmed on both lots?
Yes, by HPLC retention-time match to a reference standard (HPLC-RTM) on both certificates.
