I would have her run T4 instead. My wife runs T4 cycles and she likes them much better than T3. It makes her less hungry and she feels more at ease with T4 being less of a risk for thyroid problems if dosed too much too long. Every 100mcg of T4 will convert to 25mcg of T3. IMO I would think this is exactly what she needs.
I use 37.5 t3 for weeks 1-4 clen at 40mcgs weeks 1-2 and 5-6. Only once I feel that fat loss has plateud. Have to stress that they wont do anything without a diet in place already.
I would recommend starting with t3 25mg and clen 3days after at 20mcg just to see how she responds because everybody is different!
I'm new here but wanted to chime in in case anything I have to say it helps. I've only taken Clen (40mcgs) but never T3. I didn't like the clen so much but I was only at 110 LBS trying to lose water weight and it did not do really anything for me. I took some anavar before and it helped me lose the water weight and had so many more benefits from it like strength and better physical appearance in a small amount of time without any side effects whatsoever. I recommend running 1-2 iu's ofGH a day just from reading great rreviews about it. I've also read good reviews about nolvadex which reduces estrogen and that's suppost to assist with weight loss.
What is t3? I've ran some Clen and I didn't like the way it made me feel and it didn't seem to do much for me either but now I'm thinking maybe I should have ran t3 with it, cause I've seen people say it a lot when talking about Clen.
