01Mechanism of Action

Parameter

Chonluten

Gonadorelin

Primary target

Bronchial epithelial cells and respiratory mucosa tissue complexes

GnRH receptors on anterior pituitary gonadotropes

Pathway

Bioregulatory peptide interaction → modulation of proliferative and inflammatory pathways in monocyte/macrophage populationsAvolio 2022

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

Downstream effect

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

Feedback intact?

—

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

Origin

Khavinson bioregulator peptide complex derived from bronchial mucosa tissue extract methodology

Synthetic decapeptide (pGlu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH2) identical to native hypothalamic GnRH

02Dosage Protocols

Parameter

Gonadorelin

Typical protocol dose

10–20 mg / day

Russian bioregulator tradition dosing; not standardized in Western literature.

Frequency

—

Route

Oral (capsule) or sublingual

Sublingual claimed for enhanced bioavailability; not validated.

IV preferred (therapeutic) · SQ acceptable (diagnostic)

Evidence basis

In vitro mechanistic

RCT / Expert consensus

Duration

10–30 days per cycle

Traditional Khavinson protocol; cyclic administration common.

Continuous until pregnancy achieved or fertility goals met

3–6 month courses typical for ovulation induction.

Clinical validation

None (PubMed indexed)

—

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.

Therapeutic (hypothalamic hypogonadism)

—

5–20 mcg IV bolus every 90–120 minutes

Requires portable pulsatile pump. Dose individualized to achieve normal gonadotropin pulsatility.Robin 2026

Pulsatile interval

—

90 minutes (females) · 120 minutes (males)

Mimics physiological GnRH pulse frequency.

Half-life

—

2–4 minutes (plasma)

Necessitates frequent pulsatile administration.

Alternative protocols

—

Exogenous gonadotropins (hCG/hMG) often preferred due to convenience vs pump requirement

03Metabolic / Fat Loss Evidence

Parameter

Chonluten

Gonadorelin

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.

Relative Contraindications

Gonadorelin

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

05Administration Protocol

Parameter

Chonluten

Gonadorelin

1. Preparation

Typically supplied as capsules or sublingual tablets. No reconstitution required. Store in cool, dry place away from light.

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.

2. Oral route

Swallow capsule with water, 20–30 minutes before meals or as directed. Traditional Khavinson protocol emphasizes empty stomach for absorption.

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.

3. Sublingual route

Place tablet under tongue, allow dissolution for 1–2 minutes. Avoid swallowing immediately. Claimed to bypass first-pass metabolism.

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.

4. Timing

Morning dose preferred; may split into twice-daily if higher dose used. Consistency emphasized in bioregulator protocols.

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.

5. Cycle protocol

10–30 day cycles common in Russian tradition. Rest period of 1–3 months between cycles often recommended, though no published evidence for this approach.

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

06Stack Synergy

— no documented stacks

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
