Khavinson Bioregulator

Prostamax

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

Synthetic tetrapeptide Lys-Glu-Asp-Pro (KEDP), the Khavinson prostate-line peptide sold as Prostamax. Distinct from Prostatilen, which is a bovine prostate polypeptide extract (Cytomax) we already list. Same organ story, different molecule. Not a BPH drug in the US.

Mechanism of Action

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.

Administration

Route

IM or SC (research); some cytogens are also used mucosal

Timing

Course-based.

Fasting Required?

No — food timing not critical

Expected Timeline

Courses (days–weeks)

No honest US-label timeline. This is identity vs Prostatilen.

Who Is It For?

Need the extract

Low

That is Prostatilen. This is KEDP.

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)

Research Only

KEDP tetrapeptide. Distinct from Prostatilen (bovine prostate extract). Not a US BPH drug

WADA Status (2026)

Not Listed

Not currently on the WADA 2026 Prohibited List. Policies may change — verify before competition.

Research Chemical

US Compounding: Not eligible / not available

Prostamax vs. Prostatilen

Attribute	Prostamax	Prostatilen
Molecule	KEDP tetrapeptide	Bovine prostate polypeptide extract
Class	Synthetic cytogen	Cytomax tissue fraction
US status	Research SKU	Eastern European pharmaceutical extract

Verdict: Same organ story, different stuff in the vial. Prostamax is not a nickname for Prostatilen.
