I am 27

Started hitting the gym hard about 8 months ago (seeing great results) not lifting anything crazy but happy with progress/long journey.

Question is. I Have heard working out and eating right helps your beard grow?

My beard has always been extremely patchy. (Think full neck beard, cheeks are about 25% as much hair as there should be, some parts are completley baby bottom smooth, mustach/chin area/neck is where it comes in pretty good)

Will my beard be like this forever? I felt like at 27 i should be able to grow a full beard. My father and brother/cousins/grandparents could all grow full beards when they were 21.

I have a great jawline and would probably shave it anyway for work and what not but part of me feels like maybe its Low T? But then again thats me jumping to conclusions.

Anyone here experience late in life beard growth/seeing the gym/gains affect your facial hair?

People tell me I look like I am 18-21, I even get carded sometimes which Honestly I take as a compliment.
