I don't give much advice to first time posts about gear but you seem a little different so...
I see a lot of me in you; Skinny, can't gain a pound to save your life but you seem to have the heart for this. Gear is not your answer right now and no one is going to tell you differently. You can do a lot natty but it's going to take some time and effort. Take it from a guy who was natty 20 years pasted your age now. There's nothing easy about it but what you learn being natty will carry through the days you spend on gear down the road.
You have a year under your belt, the first few months was like a baby trying to stand on his own; not much to gain there. The next few months were spent learning more and by now you should be starting to add some mass. It will come... I promise. No one is good at anything with just a year at it; time my young man will change that.
