BMR x 1.5 if you're a sedentaray faggot
But if you want to bulk up you need to eat more than your caloric intake and make sure you're eating shit tons of protein. There are infinite guides online;https://liamrosen.com/fitness.html
You have probally seen this on /fit/ it's good and will teach you all about caloric intake and good dieting tips to bulk up.
Also stop being a faggot. It's not good for your body, it's not good for your mind, it's not good for society as a whole.
Like any addiction you can quit it. If you can't there is always therapy or just dealing with it.
Life is a struggle nobody will better your body for you. You have to do it yourself.
