Guest guest Posted March 2, 2005 Report Share Posted March 2, 2005 Unfortunately it does, Cindi. You're forgetting that before the half life would be over you'd have taken another 10mcgs, 2x. When they are testing thyroid function and want you to stop all your meds it means you have to come off T4 for 6 - 8 weeks, because it has a half life of 7 days. YOu need to come off T3 for 10 days, so you can get 6 -7 half lifes out of your system. > In a message dated 3/2/2005 4:59:58 PM Eastern Standard Time, > gnattygrl@y... writes: > > > Half life means that if you take in say 100 grams of something and > > it has a half life of 5 days then, 5 days after you take in that > > 100grams you'll have 50 grams of it left in your system > > oops...i think i did that example wrong. half-life of cytomel is 48 hours. > so two days later, the 10 mcg. would be 5 mcg. > but geez..i'm just not buying this....i use that up I am pretty sure. it > doesn't linger around in a hypo metabolic state i don't think. > cindi > > > Quote Link to comment Share on other sites More sharing options...

Guest guest Posted March 2, 2005 Report Share Posted March 2, 2005 I'm thinking this is a fine theory...makes sense and all, but: you swallow 10 mcg of Cytomel, and how much of that gets absorbed from the intestinal tract? And does it get used in nice even " half-lives " ? This sounds like a study they did on rats or something.

BUT...wonder if my body needed it because I went shopping at the mall...and since it was available - my body used it? see - I'm not so sure about this. cause they're probably testing this stuff on non -hypo folks who don't need that extra T3. valerie - what do you think?

Guest guest Posted March 4, 2005 Report Share Posted March 4, 2005 Looks like that FT3 is high, likely because you took the Armour so close to your draw - especially if you dont FEEL hyper. This would also account for the suppressed TSH (big deal, though -bloody TSH shouldn't even be one of the tests once you're on the hormones) Are you taking b12, ? your MCV, MCH, and MCHC are all near the bottom of the range, this can be the result of low b12 as well as low ferritin - since your ferritin is coming up (good job) it's likely your b12 is still low, especially if you feel tired / worn out.
