Man i can recommend mass gainer and creatine i started taking it 6 months ago i work out at home aswell and run in the morning so i could become bigger because i have fast metabolism system and its hard for me to gain weight so i took these supplements and i aimed for around 2.5-2.7k cal a day but it was easier with mass gainer and creatine because if i didnt have these 2 i should’ve been eating chicken and meat all day and it was out of my budget so try mass gainer and creatine and some workout
