So I usually keep my letro in a package at room temperature. It's liquid.
I was in a new place for two weeks, and for a good portion of it, it was in a very hot environment. For a little while it was in the bathroom in a very humid/hot environment. Would have preferred to not store it there but had to.
Typically .18 mg/day has me on the lower edge e2 wise. I've been using that amount, and now going .36mg/day and I still have oily skin, etc. It seems like my e2 is going up.
I am not cycling or anything btw.
Could the letro have gone bad?
