01Mechanism of Action

Parameter
Ovagen
Tesofensine
Primary target
Ovarian tissue chromatin complexes
Serotonin / norepinephrine / dopamine transporters (SERT / NET / DAT)Astrup 2008
Pathway
Tissue-specific peptide → Nuclear chromatin binding → Gene expression modulation → Cellular differentiation
Triple monoamine reuptake inhibition → ↑synaptic 5-HT, NE, DA → appetite suppression + thermogenesisAstrup 2008
Downstream effect
Proposed ovarian functional support, fertility regulation, hormonal homeostasis restoration
Strong appetite suppression, mild thermogenic effect, weight lossAstrup 2008
Feedback intact?
Presumed physiological — Khavinson peptides described as regulatory, not replacement
Origin
Extracted from bovine/porcine ovarian tissue; short synthetic peptides (2–4 amino acids)
Small molecule developed by NeuroSearch (Denmark) for CNS indications, repurposed for obesityAstrup 2008
Antibody development

02Dosage Protocols

Parameter
Ovagen
Tesofensine
Standard dose
10–20 mg / day (oral) or 1–2 mg SQ
Extrapolated from Khavinson-school protocols; no ovagen-specific PubMed dose studies.
0.25–0.5 mg / dayAstrup 2008
Frequency
Once daily or cyclical (10–20 days per month)
Cyclical protocols common in Khavinson bioregulator tradition.
Once daily, morning
Evidence basis
Theoretical / Russian-tradition
Phase 2b + ongoing Phase 3Astrup 2008
Duration
4–12 weeks per cycle
Khavinson protocols typically 1–3 months; repeat cycles as needed.
24 weeks per studied cycle
Route
Oral (capsule) or subcutaneous
Oral absorption assumed for short peptides; SQ route mirrors other Khavinson bioregulators.
Lower / starter dose
0.125 mg / day
Form
Oral capsule
Timing
Morning to avoid sleep disruption
Half-life
~9 days (very long)

04Side Effects & Safety

Parameter
Ovagen
Tesofensine
Reported adverse events

Theoretical hormonal effects
Ovarian stimulation — monitor for estrogen-sensitive conditions
Injection site reaction
Possible mild erythema (SQ route)
Long-term safety
Unknown — no PubMed-indexed RCTs
Heart rate / BP
Dose-dependent ↑ HR + BPAstrup 2008
Insomnia
Dose-related; mitigate with morning timing

Nausea
Common
Mood changes
Anxiety / agitation possible
Cardiovascular events

  • ·Hypertension
  • ·Anxiety disorder
  • ·Insomnia

05Administration Protocol

Parameter
Ovagen
Tesofensine
1. Oral route
Typical dose: 10–20 mg once daily. Capsule form — taken on empty stomach, 20–30 min before meals. Khavinson tradition suggests morning administration.
Oral capsule (investigational; not commercial).
2. Subcutaneous route
1–2 mg per injection. Reconstitute lyophilised powder with sterile water if required. Inject into abdomen or thigh; rotate sites.
Swallow whole with water, morning only.
3. Cyclical protocol
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.
Morning to mitigate insomnia. Do not dose evening.
4. Storage
Lyophilised: room temperature, light-protected. Reconstituted: refrigerate 2–8 °C, use within 7–14 days.
Room temp ≤25 °C, dry place.
5. Caveat
Monitor BP + HR + mood. Avoid stimulants + MAOIs.
