I personally love fina, and I add deca to all of my cycles to avoid further joints problems (I have some injuries). I usually use fina at a dosage of 100 mg./ed and deca at about 400 mg./week. I have gone much higher on the deca, but I do not seem to suffer any of the progesterone related side effects. If I were going to add anything else, it would be test, either cyp or eneth, switching over to prop closer to a meet so that it would be easier to drop water and make weight. Any long ester test makes me hold water, even when running an anti-estrogen throughout the cycle.
I have only used halo once, and I did not like the way it affected my attitude. If I ran this in combination with fina, I would probably kill someone.
Anavar is a very good choice, but can get expensive.
