Prostamax

Last reviewed: July 13, 2026 by The Peptide Catalog Team

A Khavinson prostate tetrapeptide (Lys-Glu-Asp-Pro / KEDP); the synthetic peptide has minimal direct evidence, with prostate clinical data belonging to the Prostatilen extract. Prostamax is a prostate peptide bioregulator studied for prostate-tissue support.

Overview

Core Benefits

Key Advantages
Prostate-tissue focus
Modeled from prostate tissue as a bioregulator.
Extract vs synthetic
Prostate clinical data belongs to Prostatilen, not this peptide.
Verified KEDP sequence
Sequence confirmed in an aging/chromatin study.
Proposed gene regulation
Modeled on the shared Khavinson bioregulator mechanism.
Minimal synthetic evidence
No prostate-endpoint study on the synthetic peptide.
No validated dose
Community short courses only — not trial-based.

These are educational summaries of commonly discussed effects in wellness/regenerative contexts, not guarantees.

How It WorksShort-Peptide Bioregulator — Prostate (Minimal Direct Evidence)

Target → Signal → Effect → Outcomes

1
Target

Prostate Tissue / Gene Promoters (proposed)

Prostamax is the tetrapeptide Lys-Glu-Asp-Pro (KEDP) from the Khavinson program. The proposed mechanism is the shared tissue-specific gene-expression model. Crucially, the human prostate data attributed to "Prostamax" belongs to the Prostatilen extract, a different preparation.

2
Cellular Signal

Chromatin/Aging Effect (in-vitro)

The one verified KEDP-specific study is an aging/chromatin cytogenetics study in elderly-donor cells — no prostate endpoint. A demonstration of the class mechanism, not a prostate signal.

3
Systemic Effect

Prostate Data Belongs to the Extract

Clinical prostate studies (prostatitis, BPH, sperm parameters) used the Prostatilen/Vitaprost extract in the 1990s-2000s, small and uncontrolled — NOT the synthetic KEDP peptide sold as a research chemical.

4
What You Notice

Unknown for the Synthetic Peptide

No human evidence exists for synthetic Prostamax. Do not read extract results as evidence for this compound.

What Makes This Peptide Different

Prostamax is a research tetrapeptide (KEDP) whose marketing borrows the clinical reputation of the Prostatilen extract — a different molecule. The synthetic peptide itself has one non-prostate chromatin study and no validated human use.

Protocol Notes
Khavinson prostate tetrapeptide (Lys-Glu-Asp-Pro / KEDP). The synthetic peptide has minimal evidence — prostate clinical data belongs to the Prostatilen extract, not this compound. No validated human dose.

Why This Dosing Protocol

What dose do people use? Community short courses (~1 mg/day for ~10 days) anchored to the 20 mg vial — not trial-based.

Why short courses? Convention by analogy to Khavinson pulse dosing; note the extract's clinical dosing does not transfer to this peptide.

  • NEVER freeze after reconstitution
  • Use bacteriostatic water for multi-dose

FAQ

What is Prostamax?

Prostamax is a synthetic prostate tetrapeptide — Lys-Glu-Asp-Pro, or KEDP — from the Russian Khavinson bioregulator program, marketed for prostate support. Importantly, the synthetic peptide has minimal direct evidence; the prostate clinical data attributed to "Prostamax" actually belongs to the Prostatilen tissue extract, a different preparation.

Is Prostamax proven for prostate conditions?

No. There is no controlled human evidence for the synthetic KEDP peptide in BPH or prostatitis. The clinical studies that exist used the Prostatilen extract, not this compound, and were small and uncontrolled. Sold as a research chemical.

How strong is the evidence behind Prostamax?

Weak for the synthetic peptide — one older chromatin/aging study names KEDP, with no prostate endpoint. Do not treat extract data as evidence for the synthetic form.

How long does reconstituted peptide last?

Once mixed with bacteriostatic water, peptides remain stable for up to 4 weeks when refrigerated at 2-8°C (36-46°F). Unopened powder can last 1+ year in the freezer. Get our complete Storage & Travel Guide.

Is this peptide legal to purchase?

Peptides sold "for research purposes only" are legal to purchase in the US, but are not FDA-approved for human use outside of specific medical applications. Always consult a healthcare provider before use.
