About Peptimake
Peptimake is a desk, not a company: the custom-synthesis and private-label order desk of Pepti, a peptide manufacturer operating in Guangzhou. The people who answer a Pepti-RFQ sit with production planning and QC, which is why a quote can state a lead-time tier and a document set rather than a sales estimate.

What this desk does
Pepti manufactures research-use peptides: synthesis, purification, lyophilization, fill, labelling and batch documentation under one roof in Guangzhou. Peptimake is the part of that operation that takes orders defined by the buyer rather than by the catalogue, in two forms. Custom synthesis makes a peptide to the buyer's sequence, from 100 kits (1,000 vials), typically 15 days after specification and payment confirmation. Low-MOQ contract manufacturing fills and labels a catalogue compound under the buyer's brand, from 50 kits (500 vials), with a 1-kit sample and standard lead-time tiers of 3–7, 10–14 or 14–18 days.
Both paths end in the same deliverable: a lyophilized lot in ten-vial kits with a batch Certificate of Analysis that reports the HPLC purity result and the MS identity result under a lot code printed on the vial, the carton and the certificate.
What it does not do
- Drug-substance manufacturing. Pepti does not present itself as a cGMP drug-substance (API) manufacturer or CDMO and does not publish a GMP certificate or DMF.
- Consumer sales, dosing or protocol advice.
- Milligram-scale custom synthesis for single screens; the custom minimum is 100 kits.
- Cosmetics-brand manufacturing, which Pepti handles elsewhere.
- Price lists. Quotes are written per specification.

Why a separate site
Pepti's main site, peptioem.com, covers the catalogue, the public COA library and the standard private-label OEM programme. Custom synthesis and low-MOQ private label raise different questions: how a sequence is quoted, how a specification should be written, where the minimums come from and how to check a delivery file. Those questions deserve their own pages written at the depth a buyer needs, rather than a paragraph on a catalogue site. That is what Peptimake is: the same factory, one subject, written out in full.
The figures on this site are the factory's confirmed facts and nothing else. Each page states the date it was last reviewed, and the build process checks every number against a whitelist and every date against a review log before the site is published.

How to verify what this site says
The address
The operating address is No. 18 Zhenliangyuan 2nd Road, Zhongluotan Town, Baiyun District, Guangzhou. It appears on this page, in the site's structured data and on the contact page, and it is the same address Pepti states for its production site.
The certificates
The public COA library at peptioem.com/coa is maintained by Pepti and lists catalogue lots with their HPLC and MS results. A buyer can compare any delivered lot certificate with the published record of the same product.
The sample
A 1-kit sample of a catalogue compound costs a fraction of a production order and arrives with its lot certificate. Inspect it, test it independently, and only then decide on 50 kits or more.
Scope statement
Pepti does not present itself as a cGMP drug-substance (API) manufacturer or CDMO and does not publish a GMP certificate or DMF. Peptides on this site are supplied for research use by qualified B2B buyers. For research use only. Not for human or veterinary use.
FAQ
Questions buyers ask
Where are the peptides made?
At Pepti's production site in Guangzhou. Operating address: No. 18 Zhenliangyuan 2nd Road, Zhongluotan Town, Baiyun District, Guangzhou.
Is Pepti a GMP manufacturer?
Pepti does not present itself as a cGMP drug-substance (API) manufacturer or CDMO and does not publish a GMP certificate or DMF. It manufactures research-use peptides and documents each lot with a batch COA carrying HPLC purity and MS identity results.
How do I check that a certificate is genuine?
Match the lot code on the vial, the carton and the certificate; compare the certificate with the public record of the same product at peptioem.com/coa; and, if you wish, send vials for independent HPLC and MS. The receiving checklist walks through each step.
