Does anyone here use Metrogel 1% gel for rosacea?

I'm going to bump this up again... the reason I posted this is because I have a number of large unopened tubes of this gel. I tried it and it did not work for me. I hate to throw them away when there maybe is someone here who needs this gel who may not have insurance. It is very expensive to buy. I know this is unorthodox but the tubes are sealed in boxes and are totally unused.

If a mod sees this and thinks it should be edited, by all means do so, I just thought I could help someone here out. TIA.
 
I used it a few years back and it worked but I missed last derm. appointment so never went back. I don't know if it made a difference or not. What is the expiration date?
