Hubei Jianxiang Bioscience (revision 15)

Hubei Jianxiang Bioscience Co., Ltd. (trading as HJ; hubeijianxiang.net) is a research-compound supplier trading as HJ from Xianning, Hubei, China, incorporated in 2015, supplying research peptides and raw materials with batch documentation and tracked shipping.^[1][2]

The organisation is one of twenty-eight 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]

Incorporated in 2015 and based in Xianning, a prefecture-level city in southern Hubei rather than in the provincial capital, the organisation is among the smaller-city entities covered here.^[1] Hubei has a substantial fine-chemicals sector and Xianning sits within its industrial corridor; the organisation's registered scope is in bioscience, which corresponds to its trading activity.^[1]

Purchaser reports note that shipments originate from a different city from the registered address. That is the ordinary arrangement in this sector — a registered address is a legal fact and a dispatch point is a logistical one — and the article records it because readers regularly ask which of the two the article's location field refers to. It refers to the registry record.^[1][5]

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.

Reports describe lyophilised material in crimped vials with a batch certificate, and packaging that has been consistent across submissions.^[5] Certificates in this set have generally reported purity, appearance and, on the incretin lines, a water figure.^[5][6]

Where a dispatch point differs from a registered address, no inference about manufacturing location follows: the material may be synthesised, filled and dispatched at three different sites, and nothing in the available documentation establishes which.^[2]

The catalogue is close to the sector standard. Documentation on the incretin lines is better than on the bulk lines, the gradient described on most of these articles.^[5]

Submitted reports on HJ material to July 2026 are concentrated on the incretin analogues, with reported area percent figures clustering in the high nineties and, where a water figure accompanied them, purchaser-computed peptide content in the low-to-mid eighties by mass.^[5][6]

A peptide content in the low eighties alongside a purity of 99% is the arithmetically expected pairing for a lyophilised peptide carrying a trifluoroacetate counterion and several per cent water, not an inconsistency. It is spelled out here because readers seeing the two figures on one certificate frequently take the difference for an error, and because HJ's certificates report both, which is what makes the arithmetic checkable at all.^[6]

Catalogue lines dispatch from held stock, with shipments originating from a dispatch point separate from the registered address; both are ordinary and neither affects the order.^[5]

Minimum order quantity is a single vial on listed items.

The certificate names the lot, the compound and the release date and reports both area percent purity and peptide content, which is the pairing that makes a purity figure interpretable as a mass.^[6] Submissions describe the incretin-line documentation as itemised by individual impurity rather than reported as an aggregate.

To obtain the batch record, quote the lot identifier and request the water determination and the analytical conditions. With content already on the certificate, water completes the mass balance.

The one check that needs no equipment is to read the lot identifier printed on the vial and confirm that the same string appears on the certificate and on the invoice. Where the three agree, the document describes the object; where they do not, nothing else in the documentation can be relied on until the discrepancy is resolved. See Lot traceability. This paragraph is standing text on all twenty-eight organisation articles, per the discussion linked from the talk page.

Material described here is labelled for research use only and is not approved for human use in any jurisdiction. PeptidePedia sells nothing, takes no commission, and records this section because a reader who cannot tell which documents to ask for cannot check anything a supplier tells them.

The PeptidePedia tally records 823 self-reported submissions to July 2026. Recurring themes are the documentation supplied with the incretin lines, which submissions describe as itemised rather than summary, and consistent packaging between orders.^[4] Self-selected; reception rather than quality.^[4]
