Semax vs Turinabol
Well Studied vs Moderate Research
monitor Mechanism-based · 51% Both Semax and Turinabol can raise blood pressure. Monitor BP regularly and consider adding cardiovascular support (cardarine, telmisartan, or similar).
Molecular Data
Semax Turinabol
Weight 813.93 Da 334.88 Da
Half-life 0.5-2 hours ~16 hours
Chain 7 amino acids —
Type ACTH(4-10) synthetic analog 17-alpha-alkylated anabolic-androgenic steroid (C20H27ClO2)
Key Benefits
Semax
01 Rapid brain delivery via intranasal route
02 Rapidly increases BDNF levels
03 Extensive clinical research in Russia
04 Easy self-administration
05 Modulates dopamine and serotonin systems
06 Neuroprotective effects
Turinabol
01 Promotes lean, dry muscle gains without water retention or bloating
02 Does not aromatize to estrogen, eliminating risk of gynecomastia and estrogen-related side effects
03 Favorable anabolic-to-androgenic ratio, reducing androgenic side effects relative to muscle-building potential
04 Enhances muscular endurance and recovery through increased red blood cell production
05 Increases strength without significant body weight gain, beneficial for weight-class athletes
06 Improves creatine phosphate resynthesis, supporting repeated high-intensity efforts
07 Relatively mild androgenic profile compared to most oral anabolic steroids
08 Produces slow, steady, maintainable gains rather than rapid temporary increases
Dosing Protocols
Semax
300-600mcg per dose (up to 1000mcg for intensive use) / 1-2x daily (morning recommended for cognitive boost)
Research protocol 500-750mcg 1x daily
Intensive protocol 750-1000mcg 1-2x daily
Turinabol
30-60 mg/day (male) / Split into 2 doses daily (morning and evening)
Side Effects
Semax
Mild nasal discomfort (nasal route)
Possible nasal sensation upon administration
Turinabol
Hepatic stress with elevated liver enzymes (ALT, AST) -- moderate severity, dose- and duration-dependent
HDL cholesterol suppression (significant, often 30-50% reduction)
LDL cholesterol elevation
Suppression of endogenous testosterone production via HPG axis negative feedback
Mild gastrointestinal discomfort or nausea
Back pumps (lower back tightness during exercise, common with 17-alpha-alkylated compounds)
Oily skin and mild acne
Decreased appetite in some users
Contraindications
Pregnancy or breastfeeding
Known peptide allergies
Do not exceed 4-week continuous use without medical supervision
Known or suspected prostate cancer
Breast cancer in males
Pregnancy or planned pregnancy (teratogenic risk)
Active liver disease or significant hepatic impairment
Pre-existing severe dyslipidemia or cardiovascular disease
Hypersensitivity to turinabol or related compounds
