I get ranges all over the place on the half-life of T3: anywhere from 7 hours to ~2.5 days. Now, I’ve had some people tell me that their pharmaceutical package insert said 2.5 days half-life, yet others swear that it’s more like 7-10 hours. I’ve read medical sites that quote a 1 day half-life. What the hell’s going on here? Why is the half-life of T3 so hard to pin down, does it really vary that much?
I’m trying to figure out if there is really any need to split the dosage during the day.
