The sooner you get past the fear of the needle the better; too many guys take orals only and the safest and a huge amount can be achieved solely by injectables. My first cycle was at 26 yrs old, Sustanon only, 500mgs/wk - the results blew me away. On your first few cycles don't underestimate the effectiveness of test only and (relatively) low dosages. Be sure to have all your gear, accessories, ancillaries and a proper PCT on hand before you start.
