ACE-031 vs Dianabol
Emerging vs Well Studied
monitor Mechanism-based · 46% Both ACE-031 and Dianabol suppress the HPTA axis. Combined suppression deepens shutdown and extends recovery time. Plan PCT accordingly and monitor LH/FSH/testosterone.
Molecular Data
ACE-031 Dianabol
Weight — 300.44 Da
Half-life 12-15 days ~4-6 hours
Type Soluble activin receptor type IIB-Fc fusion protein 17-alpha-alkylated anabolic steroid (C20H28O2)
Key Benefits
ACE-031
01 Significant lean mass increases (up to 1.7% in 29 days) observed in Phase 1 trials
02 Simultaneous reduction in fat mass alongside muscle gains
03 Long half-life (12-15 days) allows infrequent dosing
04 Broad TGF-beta ligand neutralization for robust anti-catabolic effects
05 Dose-dependent increases in thigh muscle volume confirmed by MRI
Dianabol
01 Rapid and dramatic increases in muscle mass and bodyweight
02 Significant strength gains within the first 1-2 weeks
03 Enhanced nitrogen retention and protein synthesis
04 Improved glycogenolysis and muscular endurance
05 Pronounced muscle fullness and pumps from increased intracellular water and glycogen
06 Effective oral kickstart while waiting for injectable compounds to saturate
07 One of the fastest-acting anabolic compounds available
Dosing Protocols
ACE-031
0.5-3 mg/kg IV every 2 weeks (clinical research doses only) / Every 2 weeks
Phase 1 Research Protocol (Healthy Volunteers) 0.1-3 mg/kg Single IV dose
Phase 2 Research Protocol (DMD) 0.5-2.5 mg/kg Every 2 weeks
Dianabol
20-50 mg/day / Split doses throughout the day
Side Effects
ACE-031
Nosebleeds (epistaxis) - most frequently reported adverse event
Gum bleeding
Telangiectasia (dilated small blood vessels visible on skin)
Skin erythema (redness)
Minor injection site reactions
Dianabol
Significant water retention and bloating (estrogen-mediated)
Elevated blood pressure from fluid retention and increased red blood cell mass
Liver stress with elevated ALT/AST enzymes (dose and duration dependent)
Back pumps (painful lower back cramping during exercise)
Increased appetite
Oily skin and acne
Suppression of endogenous testosterone production (HPTA suppression)
Mild mood changes (increased aggression, irritability, or euphoria)
Contraindications
NEVER approved for human use - clinical development discontinued
History of bleeding disorders or vascular malformations
Concurrent anticoagulant or antiplatelet therapy
Known hypersensitivity to Fc fusion proteins
Pregnancy or breastfeeding

Elevated hematocrit (above 54%) at baseline
Concurrent use of other hepatotoxic oral steroids (do not stack C17-aa orals)
Pregnancy or potential exposure to pregnant women
Heavy alcohol use (compounded hepatotoxicity risk)
Cholestatic liver conditions or history of drug-induced liver injury
