I have noticed the most difficult muscles to properly develop are the pectoral muscles and pelvic floor muscles.
My pelvic floor muscles are decent. But what I am looking for is a strong thick pelvic floor. Right now it is strong but it isn't thick and hard as i would like to it be.
Pecs my pecs are nice. They are decent and the upper chest is hard. But my pecs are not fully developed. The reason why I use steroids is so I can properly develop muscular structure. I'm using steroids so I look more decent when where tighter clothing. Well developed muscles compliment a persons appearance IMO.
