How long would a bottle of test be good for once opened?

What do you mean by open? They are sealed viales. They are or can be good for 3-5 years past experation if kept in a dark room temp loction

I used gear a year past exp. date once and swear it was a lot less potent. It may have just been shitty gear, but now I won't touch anything that's been expired. It doesn't even matter though, UGLs can put whatever damn date they want. We'll never know

I could never not use it long enough to let it expire lol

Same. Any gear I use is 4 weeks old AT MOST. When I start a cycle, the gear was either made that day or the day before. Cheaper, faster, more reliable way.
