NeolPharma MASTERON 100 is pharmaceutical-grade Drostanolone Propionate (short-ester Masteron) at 100 mg/ml. This purple-box masterpiece is the exact same ultra-clean, fast-acting Masteron used by top competitors in the final weeks before stepping on stage when they need that razor-sharp, grainy, contest-ready conditioning overnight.
