HYB — on-the-record assessments
Signed assessments of the documentation examined, with the aggregate rating and its scope.
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.
§4.1Aggregate
- Modal certainty across assessments
- High
- Assessments contributing
- 806
- Assessments published in full
- 23
- Scope of the rating
- 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.
§4.2Published assessments
Water content is reported by Karl Fischer titration with the determination method named, and the counter-ion is identified and quantified on the same certificate. Both fields together permit a mass balance to be formed, which a minority of suppliers allow.
Material from lot HYB-26-318 was submitted to Janoshik; the determination returned 98.9% against a declared 98.7%, a difference within the stated repeatability of the method. Catalogue availability corresponded to the published catalogue.
Independent determinations obtained from Medutest and from PeptideMeter on the same lot agree to within one tenth of a percentage point, and both agree with the declared figure. Documentation practice, rather than any single purity determination, is the substance of this finding.
Purity is declared by a stability-indicating chromatographic method, and the method, column chemistry and detection wavelength are all named on the certificate. The declaration is therefore assessable.
Cold-chain integrity was maintained through transit; the phase-change pack remained solid to arrival on day 4, and the shipment temperature record accompanied the consignment.
A supplementary certificate covering a lot released 14 months previously was produced from the supplier’s records on request, indicating that release records are retained rather than reconstructed. The assessor declares no interest in the supplier beyond the transactions described.
Sequence confirmation accompanied the mass-spectrometric identity for a compound whose sequence is not settled in the literature. The Institute records this because the ambiguity is the reason the requirement exists.
Consistency across lots was assessed over 9 determinations. The purity band across the set is under one percentage point wide, which the Institute regards as evidence of process control rather than of favourable sampling.
Batch traceability is complete: the identifier on the primary container corresponds to that on the certificate and to that on the commercial documentation. No excipient was present and the lyophilised cake was intact.
Material from lot HYB-25-772 was submitted to VendorInvestigate; the determination returned 98.4% against a declared 98.5%, a difference within the stated repeatability of the method. Peptide content was declared at 96.9%.
A technical enquiry concerning the reference standard used for content assignment was answered with the standard named and its source stated. The reply arrived on the fourth working day, which is unremarkable and is recorded as such.
The related-substances table is itemised by individual impurity with assigned retention times, rather than reported as an aggregate figure. Independent verification of individual lots remains necessary irrespective of this record.
The storage condition against which the stability statement was written is stated on the certificate, which permits the statement to be evaluated rather than merely noted. The desiccant sachet was enclosed within the secondary container.
Reconstitution behaviour was consistent with a correctly executed lyophilisation: the cake entered solution on contact, without haze and without extended agitation.
Independent determinations obtained from Janoshik and from VendorInvestigate on the same lot agree to within one tenth of a percentage point, and both agree with the declared figure. Figures are as reported by the testing services named and have not been reproduced by the Institute.
Fill uniformity was assessed by weighing 12 units from a single consignment against declared fill. All units fell within two per cent of the declared mass. Labelling was printed rather than handwritten on every unit.
The batch record was supplied on written request within two working days and included the chromatogram the purity figure was read from. Correspondence of this form is what the responsiveness criterion is scored from.
The tryptophan-containing line shipped in an amber vial without the point having to be raised. Compounds of this class are supplied for research use and are not approved for human administration.
A repeat determination on the same catalogue line at 11 months returned 98.6%, against 98.7% originally. No evidence of process drift is present in this sample.
Documentation was complete at first issue. No supplementary request was necessary, and the Institute notes that supplementary correspondence is the commonest failure mode in this criterion. This is a single assessor’s record and carries the weight the rubric assigns to one.
Material from lot HYB-25-509 was submitted to Medutest; the determination returned 97.9% against a declared 98.0%, a difference within the stated repeatability of the method. The consignment contained no unsecured items.
Across 22 months and 9 orders no substitution, reformulation or post-payment unavailability was encountered by this assessor. Identity was confirmed by two orthogonal methods on each occasion on which the question was put.
Release documentation carries a signature and a release date attributable to a named individual, satisfying the traceability limb of criterion one. Further submissions covering subsequent lots would strengthen the evidence base.
§4.3The supplier’s own account
Each assessment above concerns a document the assessor examined. None of them concerns what HYB says about itself, which is published at its own address and is worth reading beside them rather than instead of them.
