I'm using FX39 since some months now.... and it seems to work well. I don't know haw long it will last but I believe (being concentrate) it's not a short time.....
If memory serves, I heard straight from the source that the shelf life should be about a year if maintained properly. I decant the original bottle into small brown glass bottles (Boston Rounds) filled to the brim to ensure as long a shelf life as possible. For development times, I'd highly recommend reviewing this page: http://www.digitaltruth.com/devchart.php?doc=paterson-alt
Edit: sorry, didn't see that someone already posted this link.
I did a long term test: I've used Adox FX-39 from a full, original bottle stored for 1,5 years.
It worked very well without any problems after that long time.
Adox is now using improved bottles with a coating on the inner surface resulting in no gas-diffusion and further improved shelf-life.

That's nice to know and great for the person that wants to order two or threes bottles to save on shipping or just to have on hand so you don't run out. It's good that a company looks out for the interest of its customer instead of trying to sell more due to wasted product. My hat is off to Adox................Now, will we ever see Acutol, aka FX-14?
