Overview
Prostamax is a synthetic tetrapeptide with the sequence L-lysyl-L-glutamyl-L-aspartyl-L-proline (Lys-Glu-Asp-Pro, or KEDP). It belongs to the Khavinson short-peptide bioregulator series and is the sequence associated with prostate tissue preparations. The name is also used commercially for prostate peptide complexes derived from tissue extracts; the material supplied here is the defined synthetic tetrapeptide, characterised by sequence, formula, and molecular weight rather than by extract composition.
Reported laboratory work centres on prostate tissue in rodent models, epithelial cell cultures, and side-by-side comparisons with other members of the peptide family. Our Prostamax is supplied as a 20 mg lyophilized vial, synthesised by SPPS and HPLC purified to a ≥99% specification, with a lot-matched certificate of analysis available. It is sold for laboratory research only.

Questions about Prostamax
What is Prostamax?
Prostamax is the synthetic tetrapeptide Lys-Glu-Asp-Pro (KEDP) from the Khavinson short-peptide bioregulator series, associated in that literature with prostate tissue. It is supplied as a lyophilized research chemical for laboratory work only.
Is this a peptide complex or a single peptide?
This listing is the defined synthetic tetrapeptide KEDP, characterised by sequence, formula, and molecular weight. Some suppliers use the Prostamax name for prostate peptide complexes made from tissue extracts, which are a different kind of material entirely.
How is purity verified?
Each lot is analysed by HPLC against a ≥99% purity specification, and a lot-matched certificate of analysis is available on request. The COA records the batch identifier, purity result, identity confirmation, and physical appearance.
What does research use only mean?
The peptide is sold exclusively for laboratory research by qualified professionals. It is not approved as a drug, supplement, or cosmetic, and no human or veterinary administration guidance is provided or implied with this product.
Why does proline matter in this sequence?
Proline's side chain ties back to the backbone nitrogen, restricting rotation and fixing a kink in the chain. In a four-residue peptide that limits the shapes the molecule can adopt, which makes KEDP a useful conformational comparator against KEDG and KEDA.
How should it be stored?
Keep the unopened lyophilized vial at −20 °C, away from light and moisture. Once reconstituted, hold the solution at 2–8 °C for the planned study window, or aliquot and freeze it to avoid repeated freeze-thaw cycles.
