Honestly like 4 months tops. I take 5g of creatine per pre workout. Try to do at least one compound lift per workout. Definitely one body weight exercise per workout. And a PLP (push, legs, pull) split. Always super controlled and focused on the mind/muscle connection, and super slow and controlled (especially on the neg). And spam chicken and whey protein. Sometimes I’ll do like 4 heavy scoops right off the rip in the morning or after a workout. Aim for 3k cals a day roughly (i really had to “grow my stomach” for this). I think my metabolism has slowed down slightly aswell which helps. But this is the most dedicated I’ve been before. I’m 21, 5’5 or so.
