01Mechanism of Action

Parameter

Gonadorelin

Prostamax

Primary target

GnRH receptors on anterior pituitary gonadotropes

Chromatin in prostatic cells — pericentromeric heterochromatin regions

Pathway

GnRH → Pituitary gonadotrope → LH/FSH secretion → Gonadal steroidogenesisSharma 2026

Epigenetic modulation → heterochromatin decondensation → transcriptional derepressionDzhokhadze 2012

Downstream effect

Pulsatile LH/FSH release stimulates testicular testosterone or ovarian estradiol/progesterone synthesis; initiates folliculogenesis and spermatogenesisRobin 2026 Sharma 2026

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

Feedback intact?

Yes — pulsatile delivery preserves negative feedback loops; continuous exposure desensitizes receptors

Origin

Gonadorelin

Prostamax

Diagnostic test (pituitary function)

100 mcg IV or SQ bolus

Measure baseline LH/FSH, then 30/60/90 min post-injection. Normal response: LH ≥2× baseline.

5–20 mcg IV bolus every 90–120 minutes

Pulsatile interval

90 minutes (females) · 120 minutes (males)

Route

IV preferred (therapeutic) · SQ acceptable (diagnostic)

3–6 month courses typical for ovulation induction.

Not specified

Khavinson protocols typically 10–20 days per cycle; no long-term safety data.

Evidence basis

RCT / Expert consensus

Animal / organotypic cultureZakutskiĭ 2006 Dzhokhadze 2012

Half-life

2–4 minutes (plasma)

Alternative protocols

Human clinical dose

—

Not established

No published human trials; dosing extrapolated from Russian clinical tradition (not peer-reviewed).

03Metabolic / Fat Loss Evidence

Parameter

Gonadorelin

Prostamax

Fat loss mechanism

None — gonadorelin acts exclusively on reproductive axis

—

Indirect metabolic effects

Restoration of sex hormones may normalize body composition in hypogonadal states

Effect mediated by downstream testosterone/estradiol, not GnRH itself.

Absolute Contraindications

Gonadorelin

·Pregnancy (except therapeutic infertility protocols)
·Hypersensitivity to gonadorelin or excipients
·Hormone-dependent tumors (prostate, breast) — risk of tumor stimulation via sex hormone elevation

Prostamax

·Active prostate malignancy — epigenetic modulation effects unknown in cancer

Relative Contraindications

Gonadorelin

·Ovarian cysts or PCOS (monitor for OHSS)
·Pituitary adenoma or other sellar mass (may worsen with gonadotropin surge)

Prostamax

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

05Administration Protocol

Parameter

Gonadorelin

Prostamax

1. Diagnostic protocol

Administer 100 mcg IV or SQ bolus. Draw baseline LH/FSH, then at 30, 60, 90 minutes. Normal response: LH ≥2× baseline, FSH modest rise. Blunted response suggests pituitary pathology; exaggerated response may indicate primary hypogonadism.

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

2. Therapeutic pump setup (pulsatile)

Requires programmable infusion pump with IV catheter. Set pulse interval to 90 min (females) or 120 min (males). Bolus dose 5–20 mcg per pulse. Pump worn continuously; catheter site rotated every 48–72 hrs to prevent infection.

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

3. Reconstitution

Lyophilised gonadorelin reconstituted with sterile saline or provided diluent. Typically 0.8–3.2 mg dissolved in 8 mL for pump reservoir. Solution stable 7–14 days refrigerated.

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

4. Monitoring

For fertility protocols: ultrasound follicular tracking + serial estradiol/LH measurements. Adjust pulse dose to achieve mid-follicular LH 5–10 IU/L. Ovulation confirmed by progesterone rise or ultrasound.

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

5. Timing

Pulsatile therapy initiated at any point in cycle. Diagnostic test performed in morning (higher baseline LH). For ovulation induction, treatment begins early follicular phase.

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

06Stack Synergy

Gonadorelin

+ hCG (Human Chorionic Gonadotropin)

Multi-pathway

View hCG (Human Chorionic Gonadotropin) →

In hypogonadotropic hypogonadism protocols, gonadorelin restores pituitary LH/FSH pulsatility, while exogenous hCG directly stimulates Leydig cells (acting as LH mimetic) to maintain testosterone production. This dual approach ensures both central axis restoration and immediate gonadal steroidogenesis, preventing testicular atrophy during fertility treatment. hCG's longer half-life (24–36 hrs) complements gonadorelin's pulsatile short-acting profile.

Gonadorelin: 5–10 mcg IV every 120 min (pulsatile pump)
hCG: 1500–2000 IU SQ · 2–3× per week
Duration: 12–24 weeks for spermatogenesis induction
Primary benefit: Fertility restoration in hypothalamic hypogonadism with maintained testicular function
