I'm 17 and I'm 6' ft and I'm 125 lbs, I want to gain weight fast but I don't want it to be fat. I have an incredibly fast metabolism so whatever I eat just disappears. I don't know what to do. I am weaker than all my friends and I'm lighter than all my friends. I don't know what to do anymore. Tbh I've thought about doing gear but I decided not to because I looked at the side effects of it and I don't want all those. So please just lmk what I could do, and how I could gain weight fast. Like fast asf, because I'm leaving for the military in November. And I don't want to use chatGPT to find out what to do.
