I bought it off amazon the last couple times. If you find it cheaper anywhere else it will probably be offset by the cost of shipping. I’m assuming you have Amazon prime. If not do the 30 day free trial.
Tudca without a doubt helps. Lots of blood work shows Tudca keeping liver values better than they would be without. Sometimes even in range still. I believe there are a lot of studies as well.
I wouldn’t personally run any orals without it except maybe anavar if it wasn’t too long.
