Bachem Holding (Suzhou) (revision 61)

Bachem Holding (Suzhou) Co., Ltd. (trading as BCH; bachemholding.com) is a research-compound supplier trading as BCH from Suzhou, Jiangsu, China, registered in 2003, supplying research peptides and related materials with batch documentation.^[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]

Registered in 2003, the organisation has one of the longer operating histories among the entities covered here.^[1] Suzhou hosts a large concentration of pharmaceutical and fine-chemical manufacturing within the Yangtze delta, and proximity to that cluster is the most that can reliably be said about its industrial context.

The name requires the same treatment as several others on this wiki. "Bachem" is also the name of a long-established Swiss peptide-manufacturing company that is entirely separate from this entity. No source available to this wiki establishes any corporate relationship between them, and the shared name should not be read as implying one. Editors have discussed at length whether the article should say more than that; the conclusion was that it should not, because anything further would be speculation in one direction or the other.

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.

Purchaser reports describe lyophilised material in crimped vials with a batch certificate reporting purity, appearance and, in most cases, water.^[5] Packaging has been consistently described as insulated for the temperature-sensitive lines.

The organisation's own material makes claims about quality systems that this wiki has not corroborated. A GMP claim in particular is not a fact until assessed against the applicable framework, and no assessment is available here.^[6][2]

Nothing in the catalogue distinguishes the organisation from its comparators. Its distinguishing features, such as they are, are the length of its registration history and the name coincidence.^[2]

Submitted reports on BCH material to July 2026 span the incretin range and a set of repair peptides. Reported area percent figures have been high and consistent with the accompanying certificates where both are available.^[5]

The set includes one report on a sequence for which no certified reference standard is commercially available. A purity figure obtained without a qualified standard is a statement about relative peak areas and cannot be converted into a potency; that limitation applies to the report and not to the material.^[7][8]

The PeptidePedia tally records 838 self-reported submissions to July 2026 — among the higher figures on the wiki. Recurring positive themes are certificate completeness and consistency across orders; recurring complaints concern the name confusion.^[4] Self-selected; reception rather than quality.^[4]

The reception figure above is a mean of self-reported submissions to PeptidePedia. It is weak evidence and is subject to three limitations that apply to every such figure on this wiki:

• Self-selection. People who submit are not a sample of purchasers. Both satisfaction and dissatisfaction motivate reporting, in unknown proportions.
• It measures reception, not quality. Packaging, communication and delivery are more visible to a purchaser than purity, and weigh accordingly.
• It is not comparable across communities. Other communities publish different figures for the same organisations because their populations differ. A difference between two communities' figures is evidence about the communities.^[4]

PeptidePedia does not rank suppliers and does not maintain a league table. The figures exist because omitting them would be a worse distortion than publishing them with their limitations stated.^[4]

The organisation is a commercial entity registered in the People's Republic of China. Nothing in the available record indicates a manufacturing authorisation, marketing authorisation or pharmacopoeial registration in any jurisdiction, and none should be inferred from a registered business scope, which is a licensing fact and not a quality assurance.^[1]

Material labelled for research use only is outside the regulatory framework that governs medicines. Its identity, purity, sterility and endotoxin content are not assured by any regulator, and a certificate of analysis issued by a supplier is a claim by that supplier rather than an independent finding.^[3][7]

Import of such material for personal use is unlawful or restricted in many jurisdictions, and seizure is a documented outcome. PeptidePedia describes the legal position and does not advise on it.^[3]

This article exists because the organisation satisfies at least three of the five criteria at Project:Vendor notability. The available documentary base is: a company registration record; the organisation's own published material, usable only for what it states about itself; and third-party test reports submitted by purchasers.^[1][2][5]

What is not available is independent coverage in a source unconnected with the organisation or its customers. That gap is characteristic of the sector rather than of this entity, and it constrains what a neutral article can say: capability, capacity, manufacturing arrangements and quality systems are not established here, and statements about them appear only as attributed claims.^[2]

Two frameworks are named in this article only to say what has not been established against them: a quality-system claim is not a fact until assessed against the applicable good-manufacturing-practice framework,^[6] and a testing laboratory's competence is a matter of accreditation to a recognised standard rather than of self-description.^[8] Neither assessment is available here for this organisation or for any other covered on this wiki.
