RAD-140 vs Telmisartan
Emerging vs FDA Approved
avoid Mechanism-based · 53% Both RAD-140 and Telmisartan 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 Telmisartan
Weight 393.83 Da 514.62 Da
Half-life ~60 hours ~24 hours
Type Nonsteroidal selective androgen receptor modulator (C20H16ClN5O2) Benzimidazole derivative (C33H30N4O2)
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
Telmisartan
01 Potent 24-hour blood pressure reduction with once-daily dosing
02 Protection against AAS-induced left ventricular hypertrophy and cardiac remodeling
03 Nephroprotection through reduced intraglomerular pressure and proteinuria
04 Unique partial PPAR-gamma agonism improving insulin sensitivity and lipid metabolism
05 No negative impact on exercise performance, VO2 max, or recovery
06 Reduction of pathological vascular remodeling and arterial stiffness
07 Longest half-life of all ARBs ensuring consistent 24-hour coverage
08 Well-tolerated with a low incidence of side effects compared to ACE inhibitors (no dry cough)
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
Telmisartan
Dizziness or lightheadedness, particularly during the first few days or after dose increases
Mild hypotension, especially in volume-depleted individuals or those on concurrent antihypertensives
Upper respiratory tract infection symptoms (sinusitis, pharyngitis) - reported in clinical trials at rates similar to placebo
Back pain and myalgia (uncommon but reported)
Fatigue
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)
Pregnancy (Category D - can cause fetal injury and death; discontinue immediately if pregnancy is detected)
Bilateral renal artery stenosis
Known hypersensitivity to telmisartan or any excipients
Concurrent use with aliskiren in patients with diabetes or renal impairment (eGFR <60)
Severe hepatic impairment or biliary obstruction (telmisartan is eliminated primarily via biliary excretion)
