Is HGH use currently being controlled by MLB?

[mtortolero]

Excuse me by my ignorance but until I know MLB only is doing urine test to players according with what MLB-players union rules to detect roids.
However I understand that HGH only can be detected by blood test.
Is MLB doing blood test to players? how is controlled the use of HGH in MLB?
thanks

Yes it is on the MLB banned substances list. It can not be tested for, however, because currently a blood sample is required to determine if it's in the body. That could soon change. Until then baeball will have to continue to keep its collective head in the sand and act like HGH doesn't exist -- as the players association will not allow blood tests.
