question on female figure cycle

[gstracer]

question from my GF: she's prepping for a show her third season doing this and working closely with a nutritionist about 11 weeks In to the prep with 7 to go eating super clean with no cheating. she's taken clen nolva and Ana are in the past. currently she's been on nolva 20 as well as anavar 10 (usually gets up to around 20) and just started t3 a week ago justincreased dose to 50once a day and is taking her two weeks off from Clem right now. since about Wednesday shes been dealing with some pretty uncomfotsble abdomen bloat. right around then she had a high carb day cycled in and started a new labelled bottle of nolva same dose that we found out tight around the same time might be bunk. not sure what caused what but suddenly she got very bloated, mood swings, lethargy... chalked it up to the higher carbs until reading about the questionable nolva.... immediately switched back to an old label bottle two days ago and upped the dose to 30 after being on the other labelfor about four days or five. my questions.... if the nolva was the culprit how much longer would it take for her to return to the pre fiasco baseline? if not the nolva....can t3 possibly cause bloat? things are starting to improve but def slow....she's afraid that if she estro rebounded and high carbed at the same time she might have back peddled in her weight loss.....also any opinions or protocol on using arimidex as opposed to nolva?
