Can you still be muscular but have low T?

As the title states can you be muscular but have low T? For context I’ve done sports my whole life and started lifting at a very young age and still do to this day. I’m 31 and my physique has never looked better. However, I’ve been a firefighter for the last 10 years so my sleep schedule is not really consistent (woken up multiple times a night when on shift ) I’ve noticed in the last year or so that my libido has gone down noticeably , brain fog, and a few other of those “ low T “ symptoms.

I went to a clinic for a free consultation and my levels were 297ng so just below the low end of “normal” I’m pretty torn because I’ve been asked before if I’ve taken steroids due to how I look. So it just seems wrong to me to get on trt due to that. Curious to know if anybody has any insight or has experienced something similar. Thanks
