My Blood Work results showed I had a low level of Test and also showed My Thyroids were low. My Doctor gave me Synthroid 25mg Medication to take for my Thyroids. Doc says my Test Level should be at least an 8.8 and only was a 7.8. Is the Doc right be giving me Synthroid to cure my problem??? I'm 30 years old. 6'0 about 225lbs about 15% BF
