Tesamorelin lab reports
What the Tesamorelin record shows
Evidence through 2026-10-16TitrateLab tracks 4,568 published Tesamorelin certificate-of-analysis source records through 2026-10-16, each with a recorded purity or measured-versus-label amount result. Across 4,564 records with a numeric peptide-purity result, including zero, the median reported purity is 99.6%. Across 4,080 records with measured-versus-label dose data, 45% are within 10% of the labeled quantity. This is a public convenience sample, not a randomized market survey; one result describes one submitted sample and does not verify other batches.
Published records with a non-null purity or measured-versus-label amount result. Matching uses a normalized compound slug. No deduplication in this archive summary; relays and corrected records can remain separate. Records with neither measurement are excluded here, but can appear in the research overview's exact-token raw-record total. These are not unique certificates or batches. TitrateLab indexes reports from third-party laboratories.

Limits and missing evidence
- The testing laboratory is unattributed on 42 records.
- Coverage depends on reports that were published and available to ingest.
Tesamorelin vendor comparison
Which vendors have the strongest tesamorelin lab results?
The strongest evidence here means repeated results without an identity failure, with a larger test history carrying more weight. Vendors need at least 10 applicable tests. Purity breaks ties. This comparison does not rank dose accuracy, endotoxins, value or medical suitability.
Tesamorelin and HGH are different compounds. This comparison includes tesamorelin reports only; a vendor’s HGH results do not count toward its tesamorelin position. Find a specific batch →

How this comparison works
Each certificate counts once after the shared duplicate and attribution checks. Vendors are ordered by the 95% Wilson lower bound for results without an identity failure, then mean measured purity and test count. This gives larger test histories more weight. Missing identity tests never become passes; identity failures are excluded from purity averages. The same sample history is not available for every vendor, and submitted samples are not a random survey of everything sold. Read the method or report a correction.
