Where do I get it and what do I need to know?
In for answers
Do you need it? Have you had a blood test? If you just want it and your levels are fine then you're asking the wrong question.
JUICE ME TO THE TITS BRO
Seriously, if you want to start with blood work, order a panel from Defy Medical. Im pretty sure even if you have levels in the 2000 range they would still sell you on being seen lol, they are pretty pushy.
