Comparison table

AttributeSustanon 250Trestolone Acetate
Full nameSustanon 250 (Testosterone Ester Blend)Trestolone Acetate (MENT)
CategoryAnabolic SteroidsAnabolic Steroids
StatusPrescription drug (controlled substance)Investigational (controlled substance)
MechanismCombines 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.MENT has a 7-alpha-methyl group that prevents 5-alpha-reduction, so it stays highly active in tissues without converting to DHT. It is many times more potent than testosterone, aromatizes to estrogen, and strongly suppresses gonadotropins (its contraceptive basis).
Molecular weightBlend (varies by ester)344.5 Da (acetate)
Half-lifeMixed (~1 day to ~2 weeks across esters)~short (acetate ester)
BioavailabilityIntramuscular injectionIntramuscular injection or implant
Typical doseMedical: ~250 mg every 2-3 weeks (varies)Very potent; low absolute doses
FrequencyEvery 1-3 weeks (medical)Daily to every other day (acetate)
RouteIntramuscular injectionIntramuscular injection or subdermal implant
