Description
M-Sten Methylstenbolone
M-Sten is an anabolic-androgenic product based on 2,17-dimethyl-17b-hydroxy-5a-androst-1-en-3-one, a substance known as Methylstenbolone, M-Sten or Ultradol, which is a double methylated compound, structurally similar to 5α-dihydrotestosterone (DHT). M-Sten is known for having similar effects to that of S-drol. M-Sten does not convert to an estrogenic metabolite or have any affinity for the progesterone receptor, so estrogen-mediated side effects should be virtually non-existent.
