Damn, sorry I can't help, but at least this will bump your thread. Honestly, it's probably hard for many to give advice with you being on HRT. I'm just puzzled that you could lose muscle on 500mg test! FWIW, have you tried a refeed, or carb up? Could you just be flat and depleted from cutting cals and not training? Maybe a week of no cardio, high -volume (lower intensity) training, and plenty of good carbs?
