SS will make you more bear mode than it will make you otter or whateverthefuckyoucalledit. IA SPBR is probably what you're looking for. Also: 5'8" at 120lbs is skinny. Put on some weight, then buy clothes that you don't look like a ten year old hipster in. It sucks, but then you look way better naked and don't look like you're still going through puberty. You don't need to go full out binge and put on 70 pounds, but another 30-40 won't kill you, and if you eat right and lift right, you'll look way better. trust me.
