Prostamax peptide: Metabolic / Longevity research guide

In short: Prostamax (Lys-Glu-Asp-Pro / KEDP) is a synthetic tetrapeptide from the Khavinson short-peptide family, studied in lymphocyte chromatin assays and tissue-explant cultures. It is studied in preclinical (cell and animal) research and is supplied strictly for laboratory use, not for human or clinical use.

Not medical advice. Prostamax is a research compound. This guide does not provide dosing, diagnosis, therapy recommendations, or claims about effects in humans.

What Prostamax is

Prostamax (Lys-Glu-Asp-Pro, "KEDP") is a four-residue synthetic peptide from the Khavinson bioregulator family, studied in human lymphocyte chromatin assays and rat tissue-explant cultures.

One-paragraph overview from our research datasheet. Still scientific, but faster to read than the full mechanism list below.

Research contexts

Peer-reviewed papers discuss Prostamax in specific lab settings. The points below reflect research questions, not health claims.

Research vs. personal use: Literature describes experiments in cells and animals. That is distinct from real-world use. Our products are for laboratory research only.

Typical study contexts

Mitochondrial stress, NAD+/redox biology and nutrient-sensing pathways.

Enzyme activity, gene expression or endurance-style animal readouts.

Synthetic Lys-Glu-Asp-Pro (KEDP) tetrapeptide from the Khavinson short-peptide lineage.

Studied by differential scanning calorimetry of human lymphocyte chromatin.

Examined for cytogenetic endpoints in cells from donors aged 75-88.

Tested in rat explants of heart, lung, prostate and pancreas for tissue-matched growth.

Why Metabolic / Longevity research matters

Researchers study these compounds for mitochondrial function and cellular energy stress. Ageing and metabolic disease models are common.

Mechanisms (technical review)

Our datasheet lists mechanistic themes from preclinical work. These are research endpoints, not health claims.

Common Questions People Are Asking

What is Prostamax?

Prostamax is the name used for the synthetic tetrapeptide Lys-Glu-Asp-Pro (KEDP), developed in the Khavinson short-peptide programme. The patent behind it is titled for prostate function. It is supplied here as a laboratory research powder only.

Is Prostamax the same as Prostatilen?

No. Prostatilen is a peptide extract from bovine prostate and is studied separately. Prostamax is a defined synthetic tetrapeptide. Human prostate literature that appears in searches concerns the extract, not this peptide.

How does Prostamax differ from Cortagen?

They share Glu-Asp-Pro at the end. Prostamax starts with lysine (Lys-Glu-Asp-Pro) and Cortagen with alanine (Ala-Glu-Asp-Pro). They have different formulas and masses and are listed as separate compounds.

Is there a Certificate of Analysis for Prostamax?

Not yet. No independent analytical report has been published for this material, so no purity figure is quoted.

Is there human data on Prostamax?

The human-cell work is in vitro on lymphocytes. No human study of the synthetic peptide and no registered trial were found. Prostamax is sold strictly for in-vitro and preclinical research, not for human or veterinary use.

Is this page medical advice? Can I use Prostamax for my health?

No, and no. This article is educational only. We do not provide dosing, medical recommendations, or health claims. Our products are sold strictly for laboratory research, not for personal use of any kind.

Where do I find Prostamax specs, purity certificates and pricing?
