DHB-MED 100 (Dihydroboldenone Cypionate) is a synthetic androstane steroid and a derivative of dihydrotestosterone (DHT). It is more commonly known as the 5-alpha reduced metabolite of Boldenone (Equipoise). Just like how Testosterone interacts with 5-alpha reductase to produce dihydrotestosterone (DHT), Boldenone 5-alpha reduces into DHB (Dihydroboldenone).
