Hey buddy, SARMS will be good but at 110 lbs your diet needs the most attention, guaranteed.
First off don't run what your thinking of. It wont do hardly anything for you and you will be disappointed. I mean theres dipping your toes in but your plan, is too timid, and pointless at that dose/length of time.
If I were you I would really focus on diet, and skip the PED's for now.
However after maybe 8-12 weeks of training and SOLID 100% consistent diet, if you have made some improvement you could consider a SARMS cycle to kick it up to a new level.
If you cant make gains without PED's at all then your not going to gain much on them.
