Gonna third this. At that height/weight there is another limiting factor, not being your natural limits/test. I know it’s annoying to hear, but adding compounds won’t do anything if you don’t figure out why you aren’t gaining now. It’s pretty simple, you either aren’t eating enough or aren’t working out hard enough, likely the former. You don’t have to be anal about tracking everything you eat, although I think it’s good when you’re starting so you can have a better idea of how your growth/body como. is effected by caloric intake and your macro ratios. 1st make sure you’re getting enough calories(most important, it’s impossible to gain weight in a deficit, w/o aas, and hard to with aas) then make sure you’re getting adequate protein, and then tweak your fat/carb ratio as needed based on energy, body comp, etc. I used to wrestle so I knew exactly how many calories and protein were in everything I ate, and now it’s kind of second nature for me luckily. But you need to at least have an idea of what you’re eating so you can adjust based off what your body shows/feels. If I’m training my ass off and losing weight I know I need more calories, make sure you hit your protein and then tweak fat/CHO accordingly. Sorry typing this on my phone while driving so may not be the most coherent.
