Considering the rough start he has done well.
Usually by their first year you can expect a hognose to be 50/70 males being on the lower end of that spectrum if they are feed adequately and do not refuse food
Males do not get big I have a 2 year old that is around 85 grams while I have a 4 year old that maybe 125 grams.
Biggest male I ever owned was 160 grams.
