Anadrol vs Liothyronine (T3)
FDA Approved vs FDA Approved
monitor Mechanism-based · 60% Both Anadrol and Liothyronine (T3) can raise blood pressure. Monitor BP regularly and consider adding cardiovascular support (cardarine, telmisartan, or similar).
Molecular Data
Anadrol Liothyronine (T3)
Weight 332.48 Da 650.97 Da
Half-life ~8-9 hours ~1 day
Type 17-alpha alkylated anabolic steroid (C21H32O3) Thyroid hormone (C15H12I3NO4)
Key Benefits
Anadrol
01 Rapid and dramatic increases in muscle mass and bodyweight
02 Exceptional strength gains, often noticeable within the first week
03 Potent stimulation of erythropoietin and red blood cell production
04 Increased appetite and nutrient partitioning in some users
05 Improved recovery between training sessions
06 Full, round muscle appearance due to intramuscular water and glycogen retention
07 FDA-approved treatment for various forms of anemia
Liothyronine (T3)
01 Direct and rapid increase in basal metabolic rate
02 Enhanced fat oxidation and lipolysis
03 Improved energy levels and reduction of hypothyroid fatigue
04 Faster-acting than T4 with effects noticeable within hours to days
05 Useful when peripheral T4-to-T3 conversion is impaired (illness, caloric deficit, stress)
06 Supports body temperature regulation and thermogenesis
07 Can improve cognitive clarity and reduce brain fog associated with low thyroid function
Side Effects
Anadrol
Significant water retention and bloating (estrogenic, not aromatase-mediated)
Elevated blood pressure (fluid volume and RBC increase)
Severe liver stress and elevated liver enzymes (AST/ALT)
Back pumps and lower back pain during exercise
Headaches (often blood pressure-related)
Appetite suppression (paradoxical for a mass-building compound)
Lethargy and fatigue (hepatic strain-related)
Acne and oily skin
Suppression of natural testosterone production
Liothyronine (T3)
Tachycardia and palpitations (increased heart rate, especially at higher doses)
Anxiety, nervousness, and irritability
Insomnia and disrupted sleep architecture
Increased sweating and heat intolerance
Tremor (fine hand tremor, similar to hyperthyroid presentation)
Increased appetite despite accelerated metabolism
Loose stools or increased bowel frequency
Contraindications
Pre-existing liver disease or significantly elevated liver enzymes
Prostate cancer or breast cancer in males
Nephrotic phase of nephritis
Hypercalcemia (Anadrol can exacerbate calcium levels)
Pregnancy (Category X - causes virilization of the female fetus)
Known hypersensitivity to oxymetholone
Concurrent use of other 17-alpha alkylated oral steroids (compounded liver toxicity)
Untreated adrenal insufficiency (must correct cortisol deficiency before starting T3)
Acute myocardial infarction or unstable angina
Thyrotoxicosis or untreated hyperthyroidism
Known hypersensitivity to liothyronine or any tablet excipients
Uncorrected adrenal cortical insufficiency (risk of adrenal crisis)
