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.

Scope of supply as described. Custom peptide synthesis and amino acids. Founded 1998. ISO 9001 and cGMP certified, 1,500+ employees, 200+ patents.

§1.2What the Institute verified

Table 1. Verification status by attribute. The three states are distinct and the distinction is the substance of the dossier.

AttributeStatus
Purity by RP-HPLC with method conditionsVerified
High-resolution mass-spectrometric identity with deconvoluted average massVerified
Amino-acid analysis available on requestVerified
ISO 9001 certificationVerified
Custom-synthesis sequence confirmationVerified
Independent third-party testing on a per-batch basis for catalogue linesNot verified
Endotoxin for research-grade linesNot verified
SterilityNot assessed
Aggregate content for the amylin classNot assessed
Verified — documentation supporting the claim was examined. Not verified — the Institute looked for supporting documentation and did not find it. Not assessed — the Institute did not examine this attribute, which carries no implication about it. Verification is of documentation and never of product.

§1.2bDistribution and dispatch

The supplier maintains regional stock in six countries, so material reaches a purchaser from a warehouse in their own jurisdiction rather than from the manufacturing site: Netherlands (Rotterdam), serving European Union, typically 2-4 days; Germany (Hamburg), serving Germany, Austria, Switzerland, typically 2-4 days; United Kingdom (London), serving United Kingdom & Ireland, typically 2-3 days; United States (California), serving United States, typically 2-4 days; Canada (Toronto), serving Canada, typically 3-5 days; Australia (Melbourne), serving Australia & New Zealand, typically 3-5 days. The Institute records this because dispatch origin bears on the cold-chain history of any lot it assesses.

§1.5What this dossier does not establish

§1.6Sponsorship disclosure

GL Biochem sponsors this site and is also assessed by it. The sponsorship buys advertising placement and nothing else: no influence over the rubric, the scoring, the correspondence log or the assessments below, all of which were produced under the same procedure applied to every other supplier. The Institute states this here, on the dossier itself, rather than only on the funding page, because a reader assessing this dossier is the reader who needs it. Discounting this dossier on that basis is a reasonable thing to do.

§1.7Supplier’s own publication

Everything above concerns documentation the Institute obtained, requested or was refused. The supplier publishes its own account at the address below. The link is marked nofollow and sponsored, carries no assessment, and exists so a reader can compare the two directly rather than take the Institute’s word for what was on offer.

Nothing on that site, or this one, establishes anything about the vial you are offered. Only the certificate for that lot does, and only if it matches the vial.

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.
