Hi Monki, I too have Hashimoto and I'll be starting GW and Osta when it arrives. (Just ordered yesterday) I'm female but either way feel free to check out my log that i will be starting shortly. Truthfully, I'm hoping it's going to give me a little more energy not just inside the gym (depending on which way your Hashi is swinging. I'm 90% dominantly in hypo). No, I'm not a doctor (and proud of it) so please know this is just opinion on myself. Not giving advise. But I am not taking thyroid meds at this time. When I did it was only for a short 3 months because they stopped working and/or would get worse at a higher dose. From a great deal of research with my issues, synthroid and the likes wouldn't probably benefit me. I definitely saw some muscle wasting on cytomel, even in that time period (T3 only) and gained some weight with bloating. This may have been coincidence, but I am not sure. It did only happen while on the med. I'm trying my best to go the natural path way with clean diet and avoiding certain foods that cause severe flares for me.
