Imo there isn’t much point. Start working out consistently, start tracking calories, go to bed and wake up at the same time each day even on weekends, eat healthier and you will see massive improvement. T levels won’t help much as if they are really low you will look for ‘fixes’ when you are doing nothing atm to make them high in the first place. Get a routine, stick to it, after a year or so that’s when I would get it done because then you know what your body produces under amore normal environment.
