Only thing I can think of is GH
Look at his head! Frontal bossing etc.
Hrt clinics charge 240 for 15 IU GH, so if he took 10 IU a day for a year, it would be 58 thousand on GH alone.. He prob get acupuncture and massages and spends days at high end spas etc. his biggest cost is probably food...
Although I think it's a huge exaggeration, 600 k a year would be 1600 a day! Highly doubt that.
