Yes I did use GUGGLESTERONES, for me I use them when I've dieted down for a while (getting ready for a show) and my temperature is dropping.
I've only used T3 made by SAN, because that's the 1 I tried and it worked well, my temperature started raising and I felt like I was on fire.
I'm not telling you to take this, I'm just telling you what it did for ME, but I have never had to see a doctor about my thyroid, my temperature returns to normal after dieting is over, and only drops after dieting for a couple of months.
Maybe you should start checking your temp every few hours for alittle awhile to see if it raises during the day, because it is normal for it to be low in the morning. First thing in the morning it will not be 98.6.
