I've been reading on proviron and had a question.
I've read that it has a "shelf life" so to speak in terms of being effective. As in it only works for a certain amount of weeks then it becomes useless.
Has any one heard of this? If so what did you hear?
I realize it will differ in every one and probably dose plays a factor but are we talking a few weeks? months? year?
PS I am not talking about its half life or detectable period.
Although if you know those im interested aswell.
