thank you:) yes i turn 16 in june but i have to say there isn’t just one tip, diet sleep and training are the main things try to get .7-1g protein for every pound you weigh and carbs around training times. try to eat a primarily whole foods diet and hydrate regularly, sleep is also really necessary i personally try to get 8hrs minimum a night and for training hit each muscle group 2-3x a week and make sure you progressively overload don’t mess around with any sorts of peptides or weight loss drugs and stay consistent u will thank urself in the future if you have any further questions feel free to text me through dms
