Comparison table

AttributeMethenolone EnanthateSustanon 250
Full nameMethenolone (Primobolan)Sustanon 250 (Testosterone Ester Blend)
CategoryAnabolic SteroidsAnabolic Steroids
StatusPrescription drug (controlled substance)Prescription drug (controlled substance)
MechanismMethenolone is a DHT derivative with modest anabolic and low androgenic activity. It does not aromatize and is generally well tolerated, though the oral acetate form is not 17aa and survives via a 1-methyl group, giving lower liver stress than typical orals.Combines short, medium, and long esters so testosterone is released at staggered rates, producing a rapid initial rise followed by sustained levels. The active hormone is standard testosterone acting on androgen receptors.
