About HAISEN PEPTIDE
Guangzhou Haisen Peptide Co., Ltd. is the export arm of a peptide production facility in Guangzhou, supplying research-grade lyophilised peptides to distributors, laboratories and research-supply brands. We sell the same catalogue we manufacture, which is why the pricing is public.
What we actually do
Three operations sit under one roof in Huangpu: solid-phase peptide synthesis and purification, lyophilisation and vial filling, and the analytical laboratory that releases each lot. Keeping the third inside the building is the reason a COA can be issued per batch rather than per product family — the analyst who ran the trace is two floors from the freeze dryer.
The export side is deliberately plain. A buyer sends a SKU list, gets a line-itemised quote with freight, and receives the goods with the paperwork attached to the right box. No distributorship agreements, no territory exclusivity, no marketing claims about the compounds themselves.
Where our buyers are
Orders go to research-supply distributors in the United States, Spain, Mexico, Saudi Arabia, Qatar, Egypt, Canada and Australia, plus smaller analytical laboratories buying single boxes. The common thread is that the buyer wants a published price, a real COA, and a supplier who answers within a day.
What we do not claim
We do not claim that any compound here treats, prevents or improves any human condition, and we do not publish clinical or before-and-after claims. The products are research materials. Buyers are expected to be qualified to handle them and to check their own import rules before ordering.
Catalogue scale
The current list holds 86 product lines and 176 stock SKUs across seven research areas, priced from $3.85 to $455.70 per box. New lines are added when a compound becomes routinely requested rather than when a supplier offers it cheaply.
