01Mechanism of Action

Parameter

GHRP-6

Prostamax

Primary target

Ghrelin receptor (GHS-R1a)Bowers 1990

Chromatin in prostatic cells — pericentromeric heterochromatin regions

Pathway

GHS-R1a → Gαq → Ca²⁺ → GH release; central appetite driveBowers 2002

Epigenetic modulation → heterochromatin decondensation → transcriptional derepressionDzhokhadze 2012

Downstream effect

GH pulse + strong appetite stimulation; modest IGF-1 elevationBowers 2002

Increased sister chromatid exchange, Ag-NOR activation, reduced C-heterochromatin condensation; tissue-specific regenerative stimulation in prostate organotypic culturesDzhokhadze 2012 Zakutskiĭ 2006

Absolute Contraindications

GHRP-6

·Active malignancy
·Pregnancy / breastfeeding

Prostamax

·Active prostate malignancy — epigenetic modulation effects unknown in cancer

Relative Contraindications

GHRP-6

·Severe insulin resistance (appetite-driven caloric load)

Prostamax

·History of prostate cancer — theoretical concern re: transcriptional activation
·Undiagnosed prostatic nodules or elevated PSA

05Administration Protocol

Parameter

GHRP-6

Prostamax

1. Reconstitution

Add 2 mL bacteriostatic water to 5 mg vial → 2.5 mg/mL.

Subcutaneous or intramuscular — per Khavinson bioregulator tradition. No published human pharmacokinetic data.

2. Injection site

SQ — abdomen. Rotate sites.

If lyophilised: reconstitute with sterile water per manufacturer protocol (not standardized in literature).

3. Timing

Pre-meal for appetite support; pre-sleep for GH alignment.

Typically daily or every-other-day in Russian clinical tradition; duration 10–20 days per cycle.

4. Storage

Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.

No established biomarkers. Theoretical: PSA, prostate imaging, symptom scores (IPSS for BPH).

5. Needle

29–31G, 4–8 mm insulin syringe.

All protocols derived from non-peer-reviewed Russian clinical practice; Western regulatory approval absent.
