ED keeps your blood levels more consistent. The first time I ran fina I did 75mg eod and had pretty good results. I am running it with the cycle I am on now and will start it in about 6 weeks and will be running it 75mg ed. If you made the fina yourself with an A kit, there should not be much pain but if you have fina from the far east I can see it being a bitch shooting that ed. I would go 75mg ed and try to suck it up. If you cannot deal with the injections, then go with eod, you will still get good results, but from reading all the people's experiences with going ED seems to be the best route to go. Best of luck.
