Prostamax (Bioregulator) from Xcel Peptides

Xcel Peptides supplies Prostamax as a lyophilized bioregulator peptide for laboratory use. We test every batch independently before release, and we publish the certificate of analysis on this page, matched to the batch number on your vial.

What Is Prostamax

Prostamax is a synthetic tetrapeptide made of four amino acids: lysine, glutamic acid, aspartic acid, and proline (Lys-Glu-Asp-Pro, or KEDP). Its molecular formula is C20H33N5O9, its molecular weight is about 487.5 g/mol, and its CAS number is 473578-47-1. It belongs to the short-peptide bioregulators developed by Vladimir Khavinson and colleagues in Russia, which were designed to match small peptide fractions associated with specific tissues.

Specifications

The product is a lyophilized powder at research grade. We verify every batch through third-party HPLC and identity analysis, and we document it with a matched COA. Store the powder frozen and protect it from light. We ship every order cold-chain with tracking.

Research Applications

Researchers study Prostamax in chromatin biology and gene expression research. Typical work examines how short peptides with this charge profile interact with DNA and chromatin-associated proteins in cell-based models, and how they influence gene expression in cultured cells and tissue explants. Scientists also use it as a reference peptide when comparing Khavinson-class bioregulators.

These describe research applications, not therapeutic claims. The FDA has not evaluated this product, and researchers should not use it to diagnose, treat, cure, or prevent any condition.

Why Buy Prostamax From Xcel Peptides

Names cause confusion in this category, because the synthetic peptide shares branding with older tissue-extract preparations. Xcel Peptides lists the exact sequence and CAS number for Prostamax and tests each batch to confirm identity, so your records match the material you receive.

We also publish our results openly. You can match the batch number on your vial to the COA before you start work, instead of relying on a generic purity claim.

Storage and Handling

Store the lyophilized vial frozen and protected from light before reconstitution. Once reconstituted, refrigerate the solution and use it within a short window, since peptide stability drops considerably outside the dry state. Avoid repeated freeze-thaw cycles, since each cycle degrades the peptide structure further.

Verifying Your COA

Check three things on the COA before you use this product. First, confirm the batch number matches your vial. Second, confirm the test date is recent. Third, confirm the HPLC purity and the identity result match the KEDP sequence and the 487.5 g/mol mass for your size. If you need archived data for a previous lot, contact our team and we’ll pull it for you.

Frequently Asked Questions

What is Prostamax? It’s a synthetic tetrapeptide (Lys-Glu-Asp-Pro) from the Khavinson family of short-peptide bioregulators. Xcel Peptides supplies it as a research-grade lyophilized peptide.

Is Prostamax the same as Prostatilen? No. Prostatilen is an older bovine prostate extract, while Prostamax is a synthetic peptide with a defined sequence. Research on one does not automatically apply to the other.

Is Prostamax a hormone or related to testosterone? No. Despite the name, Prostamax is a four-amino-acid peptide. It contains no steroid and is not an androgen.

Does Prostamax come with a COA? Yes. Xcel Peptides ships every vial with a batch-matched certificate of analysis confirming identity and purity.

How should I store Prostamax? Store the lyophilized powder frozen and protected from light. After reconstitution, refrigerate the solution and avoid repeated freeze-thaw cycles.

How fast does Xcel Peptides ship this product? We ship most orders within 1 to 2 business days, with cold-chain packaging and tracking included.
