Hey there, I'll be hiking the Fanns sometime next week (15-20?), probably one way (alaudin to artuch) or loop (artuch - artuch) through the lower lakes for 3-4 days (kulikalon - alaudin). In good shape. DM if you might want to tag along (for fun and for easier logistics). Got all the equipment except for cooking stuff. Where can one get food? Artuch? Kulikalon? Vertical Alaudin? Thanks!
The camp at Alauddin lake served some food, and there is also the mountain hut above Artuch.
Otherwise yes you should bring food (large Auchan supermarket in Duchanbe) and a small camping stove is very useful.
at Mutnoe lake, there is sometimes a basecamp, but it is private, just for one group of alpinists who rented a tour and a guide. They would feed you "in case of emergency", but they are not there for this purpose. I did not go to Bolshoy Allo, I guess it is the same.
