You don't need steroids to look fit and good job on the weight loss so far. Before you even consider steroids I would get a physical/full blood panel done to see how healthy you are currently. Steroids are not something you want to be doing if you're already not healthy in my opinion. As always its your body so it is your call in the end; this is just my personal opinion.
My advice is get used to gaining muscle in a clean manner now assuming your weight loss is complete. Give that another year or 2 and you're likely to have your "fit" look. You're also likely to realize your current opinion of fit will be what you consider a skinny pussy by that time.
