About
Bulk Peptide Works, by Pepti, Guangzhou
Bulk Peptide Works is the research peptide raw material storefront of Pepti, a peptide manufacturer operating from No. 18 Zhenliangyuan 2nd Road, Zhongluotan Town, Baiyun District, Guangzhou. It exists so that a buyer of non-GLP-1 research peptides can find the identity facts, the batch records and the ordering terms for one compound on one page, without the private-label and packaging services that live on the manufacturer's main site.
The relationship
One manufacturer, one raw-material storefront
Pepti makes research peptides in Guangzhou and publishes its batch records in a public library. Its own site, peptioem.com, serves buyers who want private-label and OEM programmes, finished vials under their own label, packaging coordination and the wider catalogue. This site serves a narrower buyer: the laboratory, distributor or brand owner who needs raw material or plain vials of a specific non-GLP-1 compound, with the CAS number, the records and the terms in one place.
Keeping the two apart is deliberate. A raw-material buyer does not want to read past label artwork to find a molecular weight, and a private-label buyer does not want fourteen pages of CAS numbers. The production, the records and the supply desk behind both sites are the same; the pages are written for different jobs.
The relationship is stated on every page of this site, in the footer and in the structured data that search engines and answer engines read: Bulk Peptide Works is a brand of Pepti, and Pepti is the manufacturer.
What we hold ourselves to
Five commitments about our own conduct
The only kind of promise a supplier can make before you have ordered anything is a promise about how it behaves.
-
Name the substance by CAS, every time
The CAS number is on the page, the quotation, the label and the certificate. Trade names are shown as aliases, never as the only identifier.
-
Publish the record, not a typical one
Lots are released against a batch COA with HPLC purity and MS identity, and document availability is confirmed per lot. Public records are listed per compound. A figure from a different lot is never presented as evidence for yours.
-
Quote windows as typical, never as commitments
Lead times on this site are typical windows after specification and payment confirmation. The quotation states the window that applies to your order.
-
Claim nothing we cannot show
No certificate we do not hold, no approval we do not have, no capacity figure, no customer count, no founding year. If it cannot be checked, it is not on the site.
-
Stay in the lane
Research use only. No application, handling-for-use or medical guidance, however the question is phrased. No GLP-1 compounds and no cosmetic-grade supply from this site.
The operation
Production floor photographs
Own photographs from the Pepti production floor. The focus is the equipment and the line, not identifiable visitors or staff.
Frames from the production floor: filling needles, the stoppering turret and the stopper feed. Dispatch photographs for this site, grouped by compound, are on the order photos page.
In scope and out of scope
Being explicit about the boundary saves both sides a wasted exchange.

How to read this site
Where each kind of fact lives
Identity facts (CAS, formula, molecular weight, PubChem CID, sequence) are on each compound page in the identity table, with the PubChem link so you can check them. Batch facts (lot, purity result, molecular-weight result, test and retest dates) are in the batch-record table on the same page, copied from the public library at build time with the snapshot date shown.
Ordering facts (formats, minimums, lead-time windows) are the same on every page and come from one configuration file, so they cannot drift between pages. Anything that depends on your order, such as availability, price, packing and the delivery basis, is on the written quotation and nowhere else.
Guidance on how to compare quotes, match a certificate to a batch, choose a format, store material and qualify a supplier is in the buyer guides. They are long because the subject is, and they contain no effect language.
Checking us
Three ways to verify what this page says
A supplier page is a claim until you check it. These checks take minutes and need nothing from us.
-
Open a batch record
Pick any compound page, follow a lot link in its batch-record table, and read the PDF summary in the Pepti library. The product, lot, purity result and dates on this site must match the library; if they do not, the library is right and this site is corrected.
-
Check an identity fact against PubChem
Each identity table links the PubChem CID. The CAS number, formula and molecular weight on the page are the values listed there for that CID.
-
Order a sample kit and test a portion
1 kit (10 vials) of one compound or 5 g of powder is enough to send a portion to a laboratory of your choosing with the lot number. Their chromatogram against the certificate is the only verification that does not rely on anything we publish.
About questions
Is Bulk Peptide Works the same company as Pepti?
Bulk Peptide Works is a brand operated by Pepti for research peptide raw material. The manufacturer, the records and the supply desk are Pepti's. The brand exists to give raw-material buyers a narrower, deeper site.
Where is the material made?
In Guangzhou, at Pepti's operation at No. 18 Zhenliangyuan 2nd Road, Zhongluotan Town, Baiyun District, Guangzhou. The production photographs on this site are from that floor.
Why does the site not show a founding year or customer numbers?
Because neither would help you judge a lot, and because figures that cannot be checked do not belong on a site about documentation. Judge the operation on a sample kit and its certificate.
How do I reach the supply desk?
Through the WhatsApp button on every page or by email (email the sales desk). Replies come from Pepti Supply, the manufacturer's sales desk, during Guangzhou business hours (GMT+8), and quote the lot and the window that apply.
Judge us on a sample kit
Order 1 kit (10 vials) of one compound or 5 g of powder, read the certificate, test a portion if you wish, and decide from the record.
Prefer email? You can email the sales desk; put the compound and quantity in the subject line.
