I started gear a week before I turned 27 and only stopped two times in 26 1/2 years, once for 5 months and once for 9 1/2 months. My doses have ranged from 350mg a week to 6,500mg a week. Currently taking around 300mg test prop, 300mg NPP, 150mg masteron enanthate, and 230mg tbol, weekly total but pretty much daily shots.
