im 5'6" 150lbs 22yrs old so im gonna assume its gonna be on the lower end. i will ask the doc what they test for but im assuming its gonna be free test. i might just give him some of the test im taking n have him send that into the lab. just kinda concerned hes gonna need an a lot of it which would mean i have to get another bottle and defeat the reason i went for home brewed over underground lab test (price).
