Read this carefully. Per the supplier, each pen is filled from the same batch as the tesamorelin vial of that strength, which is why the COA library files these reports under both the vial and the pen. For the 10mg fill, Janoshik measured 10.69 mg against a 10 mg label. For the 20mg fill, it measured 17.94 mg against a 20 mg label — below the labelled amount, and printed here exactly as the report gives it. Match the lot on your pen’s label to the report for its fill before relying on it. Both reports are in the COA library (/coa/).

What researchers have looked at

  • Early pipeline (2006): a drug-evaluation review listed phase III work in HIV-associated lipodystrophy and phase II studies spanning sleep, COPD, hip fracture and immune function[1].
  • Inflammatory markers (2011): a phase III analysis of 410 people with HIV and abdominal adiposity related PAI-1, tPA, CRP and adiponectin to visceral fat[2].
  • Modern antiretrovirals (2024): a randomised trial subgroup looked at people on integrase-inhibitor regimens, which were not in use during the original phase III studies[3].
  • Neurocognition (2025): a 6-month open-label phase 2 trial in 73 virally suppressed people with HIV and abdominal obesity compared tesamorelin with standard care[4].

These studies used the licensed medicine under trial conditions and are listed by design only; they are not claims for this research pen.

Storage and handling

  • Follow the storage conditions printed on the pen label, and keep it away from light and heat.
  • Record the pen’s batch number for your inventory so it can be matched to the report for its fill.

Frequently asked questions

What amounts does the tesamorelin pen come in?

The pen listing has two options, 10mg and 20mg, chosen on this page. Both contain the same compound; the amount is the labelled content of the pen.

Is there a certificate of analysis for the tesamorelin pen?

Yes, one for each fill. The 10mg fill has Janoshik report #172070 (analysed 18 June 2026): 10.69 mg measured against a 10 mg label, purity 98.628%. The 20mg fill has Janoshik report #232266 (analysed 21 September 2026): 17.94 mg measured against a 20 mg label, purity 98.010%. Per the supplier, each pen is filled from the same batch as the vial of that strength. Both reports are in the COA library (/coa/).

Does the pen format change the compound?

No. The pen is a packaging format for research handling. The peptide is the same trans-3-hexenoyl GHRH(1-44) analogue as in the vials (PMID 17214611); no administration guidance is given for any format.

Is tesamorelin approved in Canada?

Egrifta, the licensed tesamorelin medicine, was listed by Health Canada, but its Canadian drug identification numbers are now cancelled in the Drug Product Database. This pen is research material, not a medicine.
