KEDP · Lys-Glu-Asp-Pro · prostate tetrapeptide · Простамакс

Prostamax is synthetic Lys-Glu-Asp-Pro (KEDP), the prostate cytogen. Libidon is the Cytomax complex. Prostatilen is the pharmaceutical extract. KEDP is not KED (Vesugen) and not KE (Vilon).

Not FDA-approved - research chemical

Quick answer

What it is: Prostamax is synthetic Lys-Glu-Asp-Pro (KEDP), the prostate cytogen.

How it works

Prostamax is the synthetic tetrapeptide Lys-Glu-Asp-Pro (KEDP). Prostatilen (already in the library) is a bovine prostate polypeptide extract. Same organ narrative, different material.

US compounding/research vials labeled Prostamax are the tetrapeptide SKU. They are not Vitaprost/Samprost.

Source: Khavinson cytogen / prostate-peptide literature; Prostatilen is the extract, not KEDP

Used in bioregulator stacks

Manufacturer-style organ combinations - not FDA protocols. Every name is a live leaf.

The Khavinson school

Prostamax is filed here as cytogen (synthetic short peptide), targeting the prostate. Khavinson's St. Petersburg group moved from organ extracts (Cytamins) to capsule complexes (Cytomaxes) to synthetic short peptides (Cytogens); most of the evidence comes from that one group, with little independent Western replication.

Read the full background, the proposed epigenetic mechanism, the literature limits, and how we count the canonical 41 on the Khavinson bioregulators index.

History of this molecule

One extra residue turns a vessel tripeptide into a prostate tetrapeptide in this naming system. That is the whole warning label. CIS urology used Prostatilen as a drug product; KEDP is the defined motif people buy as research powder.

Not tadalafil. Not finasteride. PSA still matters.

Caveats

A defined sequence is not an FDA indication. Prostate cytogens sit in a Russian experimental-gerontology literature with limited Western replication. “Oral bioavailability because PEPT1” is real peptide-transport biology; it is not proof this SKU treats the organ disease. Gray-market identity is a live problem - HPLC is the only way to know the vial is the sequence on the label.

Administration

Route / form
Two real SKUs: Cytomed oral capsules (swallowed) or a lyophilized research vial reconstituted for subcutaneous injection. Nobody manufactures these as sublingual tablets.
Timing
Capsules: morning, about 30 minutes before meals. Research vial (SubQ): food does not change the injection.
Empty stomach?
Capsules: yes - Swallow on an empty stomach, about 30 minutes before meals. Reconstituted vial (SubQ): food does not change the injection. Cytomed boxes sometimes print “with food” because they are labeled as supplements; the manufacturer user-guide preference is before meals.

Prostamax: oral vs SubQ

Cytomed KEDP capsule
Bioavailability
Cytomed oral KEDP capsules, swallowed with water. Cytomed still ships an oral cytogen capsule. Tetrapeptides are a weaker PEPT1 story than KE/EW dipeptides. Swallow if that is the SKU you bought; do not invent a sublingual melt. A Prostatilen rectal suppository is not this capsule.
Dose note
Cytomed folklore: 1–2 capsules daily, 10–30 day courses, morning, about 30 minutes before meals. Manufacturer protocol, not an FDA label.
Advantages
  • Official cytogen capsule SKU. No reconstitution.
  • Same sequence claim as the vial if the box is Prostamax.
  • Not a sublingual tablet. Nobody manufactures this SKU that way.
Considerations
  • Libidon is the prostate Cytomax mixture. Different class.
  • Rectal Prostatilen (CIS) is the extract’s non-injectable presentation, not a KEDP swallow.
  • KED vs KEDP is a shipping error waiting to happen.
Research KEDP vial
Bioavailability
Research SubQ from a reconstituted KEDP (Lys-Glu-Asp-Pro) vial. Prostate tetrapeptide. Prostatilen is the CIS extract (IM or rectal). Libidon is the Cytomax.
Dose note
Research-vial pattern: short course on the order of 10 days at 1–2 mg subcutaneous. Not a 12-week GLP-1 titration. Capsules skip BAC math. Do not use a Prostatilen 5–10 mg IM / suppository chart on KEDP powder. Vesugen is KED (vessels) - one residue short, different organ.
Advantages
  • Defined sequence. Vial math is legitimate when the bottle is KEDP.
  • Separable from Prostatilen/Samprost/Vitaprost (extract) if the COA is real.
  • SubQ research use is not a US BPH indication.
Considerations
  • Rising PSA is a workup, not a peptide protocol.
  • Gray-market “Prostatilen” powder is often mislabeled KEDP. Identity first.
  • Not tadalafil, not finasteride.
Recommendation: Prostamax (KEDP) is capsule-or-vial: Cytomed oral course and research SubQ. It is not Prostatilen (pharma extract, IM or rectal), not Libidon (prostate Cytomax), not Vesugen (KED), and not a sublingual tablet. Extract ampoule/suppository math stays on the Prostatilen leaf.

Safety & Considerations

Research tetrapeptide. Not finasteride, not tamsulosin, not a substitute for urologic care. Distinct from the bovine extract.

Regulatory & Legal Status

FDA Status (US)

Limits of current evidence

  • A defined sequence is not an FDA indication.
  • Gray-market identity is a live problem. HPLC beats a blog table.
  • Do not paste a sibling cytogen’s papers onto this SKU.
  • This site will not treat the named organ disease from a peptide page.

Verdict

Prostamax is the synthetic KEDP cytogen for Prostate. Khavinson’s group published in this family. That is a concentrated literature, not a Western Phase 3. Capsules and vials are different SKUs.

Interactions & Contraindications

Research tetrapeptide. Not finasteride, not tamsulosin, not a substitute for urologic care. Distinct from the bovine extract.

Frequently Asked Questions

Prostamax vs Libidon vs Prostatilen?▼
Prostamax = KEDP cytogen. Libidon = prostate Cytomax. Prostatilen = pharma extract.
Vs Vesugen?▼
Vesugen is KED (vessels). Prostamax is KEDP (prostate).
BPH drug?▼
Not in the US.
Sequence?▼
Lys-Glu-Asp-Pro (KEDP).
Capsule or vial?▼
Both. Cytomed capsules swallow; research vials reconstitute for SubQ. Prostatilen is IM or rectal extract; Libidon is prostate Cytomax. Not a sublingual tablet.
Is Prostamax the same as Prostatilen?▼
No. Prostamax = KEDP tetrapeptide. Prostatilen = prostate tissue extract.
