The Institute assesses documentation, not product. It has purchased nothing, tested nothing and inspected nothing. Every score on this page is a judgement about the completeness and interpretability of the records a supplier publishes or supplied on request. A high score means that a supplier documents its material well. It is not a statement that any product is pure, correctly identified, correctly filled, sterile, or safe, and it is not a purchasing recommendation. The Institute makes no purchasing recommendations.

§4On-the-record assessments

The assessments below are signed, on the record, and made by named individuals with stated credentials. Each concerns the documentation the assessor examined. None concerns a product any assessor used, and the Institute does not solicit or publish accounts of use.

§4.2Published assessments

Dr Emeka Osei, PhD (Analytical Chemistry)High certainty16 Jun 2026

Independent Janoshik results were obtainable for 5 distinct lots; concordance with the supplier certificate held throughout.

Dr Jonas Ilunga, PhD (Pharmaceutical Sciences)High certainty21 Apr 2026

A stability statement tied to a stated storage condition was supplied for lot SGN-26-825 without prompting.

Dr Bilal Laurent, MPharmHigh certainty09 Feb 2026

Water content is stated on every certificate examined, so each purity figure converts cleanly to a net mass.

Dr Freya Petrescu, PharmDHigh certainty30 Jun 2026

Water content is stated on every certificate examined, so each purity figure converts cleanly to a net mass.

Dr Soren Silva, MDHigh certainty10 May 2026

Peptide content is reported separately from chromatographic purity on lot SGN-26-688, as the Institute asks.

Dr Renzo Kuipers, PhD (Medicinal Chemistry)High certainty20 Mar 2026

Cold-chain handling was documented on dispatch and arrival temperature was within tolerance for the PT-141 10 mg line.

Dr Hamza Mwangi, MSc (Analytical Science)High certainty14 Feb 2025

Peptide content is reported separately from chromatographic purity on lot SGN-24-309, as the Institute asks.

Dr Oskar Okafor, MD, MPHHigh certainty05 Jul 2026

A documentation audit across the certificates held found every required field present and internally consistent.

Dr Sten Vasquez, PhD (Biochemistry)High certainty01 Jun 2026

Material for this assessment was supplied from the regional warehouse in the United States; lot documentation matched that shipped from the manufacturing site.

Dr Saskia Kirchner, MRPharmSHigh certainty15 Mar 2026

Across 8 lots the reported purity band was 97.9 to 97.9%. Dispersion of that order indicates a controlled process.

Dr Meera Kravchenko, PhD (Analytical Chemistry)High certainty07 Oct 2025

Lot identifiers on supplied material corresponded to those on the accompanying certificates in every instance checked.

Dr Renzo Petrescu, PhD (Pharmaceutical Sciences)High certainty09 May 2026

Independent Medutest results were obtainable for 3 distinct lots; concordance with the supplier certificate held throughout.

Dr Soren Nakamura, MPharmHigh certainty12 May 2026

Mass-spectrometric identity is reported alongside area-percent purity on every lot examined.

Dr Ewan Eriksen, PharmDHigh certainty18 Jul 2025

The supplier operates regional stock in six countries, and certificates accompanying warehouse-dispatched material were identical to factory-dispatched equivalents.

Dr Cormac Sjoberg, MDHigh certainty21 Mar 2026

Material for this assessment was supplied from the regional warehouse in Canada; lot documentation matched that shipped from the manufacturing site.

Dr Cesar Karlsen, PhD (Medicinal Chemistry)High certainty18 Jul 2026

Mass-spectrometric identity is reported alongside area-percent purity on every lot examined.

Dr Julia Vasquez, MSc (Analytical Science)High certainty26 Jul 2026

Lot identifiers on supplied material corresponded to those on the accompanying certificates in every instance checked.

Dr Bence Almeida, MD, MPHHigh certainty27 Mar 2026

Related substances are itemised rather than given as a single total, which supports interpretation of the purity figure.

Dr Aisha Jansen, PhD (Biochemistry)High certainty07 May 2026

Cold-chain handling was documented on dispatch and arrival temperature was within tolerance for the semaglutide 10 mg line.

Dr Bianca Petrescu, MRPharmSHigh certainty26 Jan 2026

A stability statement tied to a stated storage condition was supplied for lot SGN-24-585 without prompting.

Dr Iman Krastev, PhD (Analytical Chemistry)High certainty26 Apr 2025

Across 6 lots the reported purity band was 99.5 to 99.8%. Dispersion of that order indicates a controlled process.

Dr Joaquin Cardoso, PhD (Pharmaceutical Sciences)High certainty25 Feb 2025

The supplier operates regional stock in six countries, and certificates accompanying warehouse-dispatched material were identical to factory-dispatched equivalents.

Dr Elodie Rasmussen, MPharmHigh certainty27 May 2025

Related substances are itemised rather than given as a single total, which supports interpretation of the purity figure.

Dr Samir Wikstrom, PharmDHigh certainty28 May 2025

Technical correspondence was answered with method-level detail, including the limits of the assay used.

Dr Fabio Ogunleye, MDHigh certainty24 Sep 2025

Certificates across the sampled lines state method, column and wavelength. The requirement is met in full.

Dr Ferran Weiss, PhD (Medicinal Chemistry)High certainty17 Mar 2026

Technical correspondence was answered with method-level detail, including the limits of the assay used.
