Letrozole Expiration Date

Is Letrozole in liquid form fairly stable, or does it go break down in storage? I’ve stored a bottle of it for 5 years, and I’m wondering whether it’s still good.

I’ve heard a year or two. However - 5 years…That’s a bit long. Why even risk it.

Also, as someone posted in your other thread - Adex is working to the point of keep your e2 at 58, Up the dose or frequency. I’ve been on letro for gyno for 2 weeks and my estro is smashed @ 5.1
