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.

Documentation completeness and interpretability. Not product quality.
What the certainty band records
High — the strength of the Institute's own evidence base about this supplier, being the breadth of the documentary sample and the number of assessment cycles behind it. It is not a quality verdict and nothing on this site presents it as one.

Figure 3. The six criterion scores. The certainty band above is not plotted here: it records how much documentary evidence the Institute holds about this supplier and sits on a different axis from a zero-to-five criterion score, so drawing the two on one scale would invite a comparison that is not available.

§4.2Published assessments

No assessment has been published in full for this supplier.

§4.3The supplier’s own account

Each assessment above concerns a document the assessor examined. None of them concerns what GSP says about itself, which is published at its own address and is worth reading beside them rather than instead of them.

Nothing published by the Institute is medical advice, a diagnosis, a prescription, a treatment recommendation or a purchasing recommendation. Compounds supplied for research use are not approved for human or veterinary use in any jurisdiction, and a favourable analytical assessment of a supplier is not a statement that any product is safe or effective. The Institute publishes certainty ratings and never recommendations. No telephone number, messaging handle or ordering channel appears anywhere on this site.
