RAD-140 vs Trenbolone
Emerging vs Moderate Research
avoid Mechanism-based · 53% Both RAD-140 and Trenbolone carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently.
Molecular Data
RAD-140 Trenbolone
Weight 393.83 Da 270.37 Da (base)
Half-life ~60 hours ~3 days (acetate)
Type Nonsteroidal selective androgen receptor modulator (C20H16ClN5O2) 19-nortestosterone derivative (C18H22O2), trienone steroid
Key Benefits
RAD-140
01 Potent anabolic activity in muscle tissue with high oral bioavailability
02 Tissue-selective action sparing the prostate and other androgen-sensitive organs
03 No aromatization to estrogen (no estrogen-related side effects such as water retention or gynecomastia)
04 No conversion to DHT (reduced risk of hair loss and prostate stimulation compared to testosterone)
05 Long half-life (~60 hours) permitting convenient once-daily oral dosing
06 Neuroprotective properties observed in preclinical models
07 Increased lean body mass and reduced fat mass in preclinical studies
Trenbolone
01 Exceptional lean muscle mass accrual with minimal water retention due to non-aromatizing profile
02 Dramatic body recomposition capability -- simultaneous muscle gain and fat loss even in caloric deficit
03 Approximately five times the anabolic and androgenic potency of testosterone (500:500 ratio)
04 Powerful anti-catabolic effects through glucocorticoid receptor antagonism, protecting muscle during dieting
05 Significant increases in strength across all compound movements, often rapid in onset
06 Enhanced nutrient partitioning, directing calories toward lean tissue accretion over fat storage
07 Pronounced muscle hardness, density, and vascularity due to absence of estrogenic water retention
08 Increased IGF-1 production in muscle tissue, amplifying growth signaling pathways
Dosing Protocols
RAD-140
10-20 mg/day / Once daily (oral)
Trenbolone
200-400 mg/week / Every other day (acetate) or 2x per week (enanthate)
Recomposition - Moderate (Acetate) 200-300 mg/week (50-75 mg every other day) Every other day
Advanced Cutting (Acetate) 300-400 mg/week (75-100 mg every other day) Every other day
Lean Bulk (Enanthate) 200-400 mg/week 2x per week
Contest Preparation - Advanced 300-500 mg/week Every other day (acetate) or 2x per week (enanthate)
Side Effects
RAD-140
Testosterone suppression (dose-dependent, occurs in virtually all users by week 4-6)
Liver enzyme elevation (ALT, AST increases reported in clinical and anecdotal data)
Hair shedding (temporary, typically resolves after discontinuation)
Headaches (most common in the first 1-2 weeks, often transient)
Nausea (mild, usually with initial doses or on an empty stomach)
Lipid disruption (HDL suppression, LDL elevation)
Mild insomnia or sleep disturbance
Reduced libido and mood changes related to testosterone suppression
Trenbolone
Insomnia and severely disrupted sleep architecture (one of the most universally reported side effects, affecting the majority of users)
Night sweats, often drenching, requiring sheet changes
Significantly reduced cardiovascular endurance and aerobic capacity
Increased aggression, irritability, and shortened temper
Anxiety and restlessness, particularly at higher doses
Tren cough: acute, intense coughing fit lasting 30-90 seconds immediately after injection, caused by a small amount of oil entering a blood vessel
Dark-colored urine (oxidized metabolites; not necessarily indicative of kidney damage but should be monitored)
Elevated body temperature and increased sweating throughout the day
Acne and oily skin, particularly on shoulders, back, and chest
Accelerated hair loss in those genetically predisposed to male pattern baldness
Profoundly suppressive of natural testosterone production (near-complete HPT axis shutdown)
Increased heart rate and elevated blood pressure
Contraindications
Pre-existing liver disease or elevated liver enzymes at baseline
Hormone-sensitive cancers (prostate cancer, certain breast cancers not being treated under clinical supervision)
Pregnancy or potential pregnancy (teratogenic risk from androgen receptor agonism)
Breastfeeding
Age under 25 (incomplete endocrine system maturation and higher risk of HPG axis disruption)
Concurrent use of hepatotoxic medications without medical supervision
Known cardiovascular disease (insufficient safety data for this population)
First steroid cycle or limited anabolic steroid experience (trenbolone is strictly an advanced-only compound)
Pre-existing cardiovascular disease, cardiomyopathy, or significant cardiac risk factors
History of mental health conditions: anxiety disorders, depression, bipolar disorder, or psychotic episodes
Liver disease or significantly elevated liver enzymes
Kidney disease or impaired renal function
Uncontrolled hypertension
Polycythemia (hematocrit above 54% at baseline)
Prostate cancer or history of hormone-sensitive cancers
Active or recent substance abuse (trenbolone's psychological effects can exacerbate addictive behaviors)
Pregnancy or potential for pregnancy in female partners (extremely virilizing compound)
