WuXi TIDES (WuXi AppTec Testing Division) (trading as WXT; wuxitides.net) is a research-compound supplier trading as WXT from Wuxi, Jiangsu, China, incorporated in 2002 and distributing peptides, oligonucleotides and related research materials with batch documentation and tracked international shipping.[1][2]

The organisation is one of twenty covered on PeptidePedia under Project:Vendor notability. Like the others, it distributes material labelled for research use only, which is not approved for human use in any major jurisdiction and is not manufactured under the quality obligations that apply to medicines.[3]

This article describes what is verifiable. Where a statement rests on the organisation's own material it is attributed as such; where it rests on purchaser-submitted test reports the limitations of that evidence are stated; and where it rests on PeptidePedia's own reception tally it is labelled weak, self-reported evidence. Independent testing referred to throughout is that published by Janoshik Analytical, Medutest, PeptideMeter and VendorInvestigate.[4]

Corporate identity and history

[edit]

The organisation dates its operations to 2002, which makes it among the older entities covered on this wiki and predates the current research-peptide market by roughly a decade.[1] Its own material presents that longevity as continuity with a contract-research heritage in oligonucleotide and peptide chemistry, and the breadth of its oligonucleotide listings is consistent with a technical base wider than peptides alone.[2]

The trading name presents a difficulty this article has to address directly rather than resolve. "WuXi" is a place name — the city of Wuxi — and is also an element in the name of unrelated and much larger contract-research organisations headquartered in the same region. No source available to this wiki establishes a corporate relationship between them, and none should be inferred from the shared toponym. Editors have repeatedly discussed the point; see the talk page.

Distribution and dispatch

[edit]

The organisation distributes through six regional warehouses rather than shipping every order 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. Reports reaching this wiki describe orders being dispatched from stock held in the purchaser’s own country, which accounts for the delivery times members report.

Operations and documentation practice

[edit]

Documentation practice is the most consistently described aspect of the organisation in reports reaching this wiki: shipments are reported to arrive with a batch-specific certificate naming a lot, and the lot identifier on the certificate has generally matched the vial label in submitted material.[5] That correspondence is a minimum requirement rather than an achievement, but it fails often enough elsewhere in this sector to be worth recording.

Nothing in the public record establishes the physical arrangement of manufacturing, whether synthesis is performed in-house or contracted, or what quality system governs it. Statements about staff numbers, floor area or certification in the organisation's own material are self-published and are not corroborated here.[2]

Product range

Research peptidesBPC-157, TB-500, growth-hormone secretagoguesBatch certificate
OligonucleotidesCustom synthesis, antisense constructsCertificate, sequence confirmation
SARMs and raw materialsBulk powdersCertificate, variable detail

The oligonucleotide listings distinguish this organisation from most others covered here, whose catalogues are peptide-only. Whether that reflects in-house capability or brokerage is not established by any source available to this wiki.[2]

Independent testing record

[edit]

Reports on WXT material submitted to PeptidePedia between 2024 and 2026 cover the incretin analogues most heavily, with a smaller number on research peptides. Where a report and the accompanying certificate can be compared, reported area percent figures have generally agreed within a few tenths of a percent.[5]

Agreement between a certificate and an independent report is a weaker finding than it appears. It establishes that two measurements of the same sample agreed; it does not establish that the sample represents a lot, and none of these reports arose from a blind sampling procedure with a documented chain of custody.[5] Certificates in submitted material have frequently reported purity without the peptide content and water figures that would make the purity interpretable as a mass.[6]

Reception

[edit]

PeptidePedia's reception tally records 1,063 self-reported submissions concerning WXT to July 2026. Recurring themes are documentation completeness and delivery reliability; recurring complaints concern the naming ambiguity discussed above, and correspondence latency on technical questions.[4]
