I know you didn’t ask me, but I was going to share what I have read on the subject. I use test almost exclusively and thus I always use finasteride, year round. I did my first cycle ever without finasteride and had great gains, but I cycle now with finasteride at 2.5-5 mgs a day depending on how much test I am using.
I have never noticed a difference with or without the finasteride other than the fact that my hair is full and thick. I never had a hair loss problem, but if you use alot of test for a long time, cycle after cycle, you are just tempting fate, so I thought I could use finasteride as protection. My main reason for starting the fina was both of my grandfathers had prostate cancer young, one died, the other had a nasty chemo schedule. My skin seems to be less oily. I think that there is documentation to the effect that DHT is a major effector of sebum, which is indicated in both hair loss and acne development.
But then again if you think about it, some of the most potent AAS’s are DHT-deriavitives, masterbolan, primobolan, trenbolone and winstrol. So I don’t know, this has always been a interesting question. I think test is best, fast-acting test of course. Suspension or propionate only.
