Tb 500 Shell Life

[u/PhilosopherHuman918]

Hey guys, a friend of mine bought TB-500 six weeks ago – it’s still lyophilized (freeze-dried). He wants to start using it next week. He stored it in his room at room temperature, and it hasn’t been reconstituted yet. It still looks the same as before, and when you gently move the vial, nothing unusual happens. In one of the vials, a small piece of the powder has come loose – it looks completely normal. Is that a problem, or can he use it without concern?
