01Mechanism of Action

Parameter
GHRP-6
Ovagen
Primary target
Ghrelin receptor (GHS-R1a)Bowers 1990
Ovarian tissue chromatin complexes
Pathway
GHS-R1a → Gαq → Ca²⁺ → GH release; central appetite driveBowers 2002
Tissue-specific peptide → Nuclear chromatin binding → Gene expression modulation → Cellular differentiation
Downstream effect
GH pulse + strong appetite stimulation; modest IGF-1 elevationBowers 2002
Proposed ovarian functional support, fertility regulation, hormonal homeostasis restoration
Feedback intact?
Presumed physiological — Khavinson peptides described as regulatory, not replacement
Origin
Synthetic hexapeptide; first-generation GHRP from Bowers groupBowers 1990
Extracted from bovine/porcine ovarian tissue; short synthetic peptides (2–4 amino acids)
Antibody development

02Dosage Protocols

Parameter
GHRP-6
Ovagen
Standard dose
100–200 mcg per injectionBowers 1990
10–20 mg / day (oral) or 1–2 mg SQ
Extrapolated from Khavinson-school protocols; no ovagen-specific PubMed dose studies.
Frequency
1–3× per day
Once daily or cyclical (10–20 days per month)
Cyclical protocols common in Khavinson bioregulator tradition.
Lower / starter dose
50 mcg per dose
Evidence basis
Phase 1 + clinical practiceBowers 1990
Theoretical / Russian-tradition
Duration
8–12 weeks on / 4 off
4–12 weeks per cycle
Khavinson protocols typically 1–3 months; repeat cycles as needed.
Reconstitution
Bacteriostatic water
Timing
Pre-meal preferred for appetite support
Half-life
Route
Oral (capsule) or subcutaneous
Oral absorption assumed for short peptides; SQ route mirrors other Khavinson bioregulators.

04Side Effects & Safety

Parameter
GHRP-6
Ovagen
Hunger
Pronounced — defining feature vs ipamorelin
Cortisol elevation
Mild
Prolactin elevation
Mild
Injection site reaction
Mild
Possible mild erythema (SQ route)
Cancer risk
Contraindicated in active malignancy
Pregnancy / OB
Avoid
Reported adverse events
None documented in indexed literature
Theoretical hormonal effects
Ovarian stimulation — monitor for estrogen-sensitive conditions
Long-term safety
Unknown — no PubMed-indexed RCTs
Absolute Contraindications
GHRP-6
  • ·Active malignancy
  • ·Pregnancy / breastfeeding
Ovagen
  • ·Active hormone-sensitive malignancy (breast, ovarian, endometrial)
  • ·Pregnancy
Relative Contraindications
GHRP-6
  • ·Severe insulin resistance (appetite-driven caloric load)
Ovagen
  • ·History of estrogen-sensitive tumors (monitor)
  • ·Polycystic ovary syndrome (PCOS) — theoretical ovarian hyperstimulation risk
  • ·Endometriosis or fibroids (estrogen-responsive conditions)

05Administration Protocol

Parameter
GHRP-6
Ovagen
1. Reconstitution
Add 2 mL bacteriostatic water to 5 mg vial → 2.5 mg/mL.
Typical dose: 10–20 mg once daily. Capsule form — taken on empty stomach, 20–30 min before meals. Khavinson tradition suggests morning administration.
2. Injection site
SQ — abdomen. Rotate sites.
1–2 mg per injection. Reconstitute lyophilised powder with sterile water if required. Inject into abdomen or thigh; rotate sites.
3. Timing
Pre-meal for appetite support; pre-sleep for GH alignment.
Common pattern: 10–20 days on, 10 days off. Aligns with menstrual cycle phases in some protocols. Repeat cycles for 2–3 months, then assess.
4. Storage
Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.
Lyophilised: room temperature, light-protected. Reconstituted: refrigerate 2–8 °C, use within 7–14 days.
5. Needle
29–31G, 4–8 mm insulin syringe.
