So I was doing some spring cleaning and in the course of my cleaning I found 4 vials of MTII and I was wondering if they're still good? They're probably pushing 6 years but they've been frozen and are not reconstituted. Also, if they're too old they're still sterile right? So injecting would do no harm it just wouldn't yield desired results correct? Found on a website that peptides are still good four years, this is obviously longer than that but what happens, they get less and less effective over time?
