Supplier comparison — all 28 dossiers
Every assessed supplier in one sortable, filterable table. The default order is alphabetical and no ranking is published.
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.

Table 1. All assessed suppliers. Sort on any column. Sorting on the total produces something a reader will treat as a ranking, which is why the coverage limitation of each dossier appears in the table rather than behind a link.

Criterion scores are on the anchored zero-to-five scale published in the rubric. The total is the weighted sum out of 100. Each supplier's own site is linked from its name, marked nofollow and sponsored, so that the Institute's account and the supplier's can be read side by side. The suppliers listed lower down the directory, on which no dossier has been opened, carry no link. | ||||||||||||
§2How to read this table
- The total conceals more than it shows. Two suppliers with the same total may differ entirely in which criteria they meet, and the per-criterion columns are the informative ones.
- Coverage differs. The last column states what each assessment covered. A score obtained over a supplier's incretin lines says nothing about its growth-hormone-axis lines.
- No column measures product. Every column measures documentation.
- Absence is not a judgement. A supplier not in this table has not been assessed, which is different from having been assessed and scored poorly.
