01Mechanism of Action

Parameter

Ovagen

Semax

Primary target

Ovarian tissue chromatin complexes

BDNF / NGF expression + monoamine modulationKaplan 2017

Pathway

Tissue-specific peptide → Nuclear chromatin binding → Gene expression modulation → Cellular differentiation

↑ BDNF + NGF synthesis + 5-HT modulation → neuroplasticity + anxiolysis + cognitive enhancementKaplan 2017

Downstream effect

Proposed ovarian functional support, fertility regulation, hormonal homeostasis restoration

Improved memory + attention; reduced anxiety; neuroprotection in ischemiaKaplan 2017

Origin

Extracted from bovine/porcine ovarian tissue; short synthetic peptides (2–4 amino acids)

02Dosage Protocols

Parameter

Ovagen

Semax

Standard dose

10–20 mg / day (oral) or 1–2 mg SQ

Extrapolated from Khavinson-school protocols; no ovagen-specific PubMed dose studies.

200–600 mcg / dose intranasalKaplan 2017

Frequency

Once daily or cyclical (10–20 days per month)

Cyclical protocols common in Khavinson bioregulator tradition.

2–3× per day during cognitive demand

Evidence basis

Theoretical / Russian-tradition

Human-mechanistic + Russian clinicalKaplan 2017

Duration

4–12 weeks per cycle

Khavinson protocols typically 1–3 months; repeat cycles as needed.

10–14 day cycles, repeated PRN

Route

Oral (capsule) or subcutaneous

Oral absorption assumed for short peptides; SQ route mirrors other Khavinson bioregulators.

Absolute Contraindications

Ovagen

·Active hormone-sensitive malignancy (breast, ovarian, endometrial)
·Pregnancy

Semax

·Pregnancy / breastfeeding

Relative Contraindications

Ovagen

·History of estrogen-sensitive tumors (monitor)
·Polycystic ovary syndrome (PCOS) — theoretical ovarian hyperstimulation risk
·Endometriosis or fibroids (estrogen-responsive conditions)

Semax

·Active psychiatric instability
·Concurrent strong stimulants

05Administration Protocol

Parameter

Ovagen

Semax

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.

Pre-formulated nasal spray (commercial) or research vial reconstituted with bacteriostatic water.

2. Subcutaneous route

1–2 mg per injection. Reconstitute lyophilised powder with sterile water if required. Inject into abdomen or thigh; rotate sites.

Intranasal — 2–3 sprays per nostril per dose. Tilt head slightly back.

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 + early afternoon. Avoid evening (sleep disruption).

4. Storage

Lyophilised: room temperature, light-protected. Reconstituted: refrigerate 2–8 °C, use within 7–14 days.

Refrigerate after reconstitution; light-protected.

5. Caveat

—

Cycle on/off to avoid neurochemical adaptation.

06Stack Synergy

Ovagen

— no documented stacks

Semax

+ Selank

Moderate

View Selank →

Semax (cognitive enhancer, BDNF/NGF) and Selank (anxiolytic + immune) form the canonical Russian "neuro stack" — both intranasal peptide bioregulators with complementary axes. Semax for cognitive demand; Selank for stress mitigation.

Semax: 200–600 mcg intranasal · morning + afternoon
Selank: 150–300 mcg intranasal · midday + early evening
Primary benefit: Cognitive enhancement + stress mitigation
