A useful Tesamorelin 10mg COA connects the named material and lot to an independent laboratory, its methods, and the results for each tested sample. Read identity, HPLC purity, and measured content as separate fields. Together, they give a much clearer purchasing record than a purity percentage alone.
This Panda Peptides documentation guide uses an original ILS Laboratories certificate as a worked example. Open the complete two-page certificate or verify it with ILS as you read. Report reviewed September 11, 2026.
1. Match the report before comparing the numbers
The example identifies Tesamorelin, labeled content 10mg, lot PP2604-039B, tested for Panda Peptides. ILS issued certificate COA-2026-V0BGGG with an analysis date of August 18, 2026. These identifiers let a purchasing team retrieve the same document and distinguish it from another product size or lot.
For an order, match the supplier’s lot information and the received label to the report. An authentic report and a confirmed shipment match are two different parts of traceability; keep both in the purchasing record.
2. Read identity, purity, and content separately
- Identity: the example reports Tesamorelin as “Confirmed” using HPLC-RTM. Record the method exactly as written; this field is not labeled mass spectrometry.
- HPLC purity: a chromatographic result expressed as a percentage. For peptide HPLC with UV detection, purity is commonly assessed from the main peak area relative to the total integrated peak area. The result depends on the analytical method.
- Measured content: the certificate separately reports “Net Peptide Content” in mg. This is a different field from the nominal 10mg label and the HPLC percentage.
Bachem’s analytical quality-control guide explains why chromatographic purity and peptide content are different measurements. Terminology and units also matter: some laboratories report content as a percentage, while this ILS certificate reports mg. Do not multiply the nominal 10mg label by HPLC purity and treat that calculation as a measured content result.
3. Compare both tested samples
The original certificate includes two sample rows, making the underlying results available alongside the headline figure:
| Sample | HPLC purity | Reported content | Identity |
|---|---|---|---|
| Dedicated V0 | 99.48% | 10.49mg | Confirmed |
| Conformity V1 | 99.50% | 10.28mg | Confirmed |
These rows illustrate why a higher purity percentage does not necessarily mean a higher measured mg result. Preserve both sample rows when comparing suppliers; a single average hides that distinction. The certificate’s results relate to the samples tested.
4. Keep a consistent comparison record
Use the same fields for each supplier so the comparison is about documented evidence:
- Product name, nominal amount, lot, and the report-to-order match.
- Issuing laboratory, certificate number, report date, and direct verification result.
- Identity method and result, HPLC result, and content result with its units.
- Number of samples and each individual result, not only the best value.
- Any additional panels relevant to your laboratory’s purchasing specification, including their methods, units, limits, and reported outcomes.
Save the original report and the date you verified it. Read the complete second page for additional panels rather than inferring them from an HPLC result.
