yeh i got broad shoulders.. my triceps are normal

In most likelihood you don't have a lagging chest. Because the muscles are stretched over a longer area they just look flat. If someone without broad shoulders had the same chest it would bulge.

Do an experiment: Take a piece of paper and lay it flat on a table. Push it in a little bit from each side. Look how much it pops up off the table. The same principle applies to your chest. If each of your shoulders was one inch narrower then your chest would look far more developed.

There are only a lucky few that have broad shoulders AND highly developed chests. That is often also the product of targeting the chest. Have you thought of doing a chest only steroid cycle?
