I was doing them back in Russia and a PRP injection there would cost around $80.
I keep doing hyaluronic acid injections every 3 months just to be safe, whatever I am doing it seems to be working, so I continue doing them. Right now I live in Georgia they cost around $105 here ($90 for the syringe, $15 for the doctor).
SVF seemed to have a much stronger effect than PRP, it's hard to quantify, but I would say a single SVF felt close to all the PRPs I did before.
I think it's worth it considering getting a paid surgery in a "2nd world" country, like Kazakhstan, Turkey, Russia (pre-war, feels uneasy going there now) and etc. Things there cost 10 times less and most surgeries, where hospitals don't need very advanced equipment, are probably done on the same level as "1st world" countries.
