All Depends how sensitive your hair follicles are to androgens
Finasteride will prevent the conversion of 70-75% if 'm not mistaken so either way your testosterone levels will be extremely elevated either way. if your still shedding, and thinning while being natural, then chances are steroids will only accelerate the inevitable. Best bet is to find a topical androgen such as RU58841 in conjunction with finasteride while on cycle to topically, and systemically inhibit DHT. everyone is different, and their is to many variables involved. It's trial, and error.
Once your blood levels are stable I find I experience nothing in terms of sides. When I start dropping orals, increasing doses, and in return fluctuating hormone levels is when I experience side effects such as acne break out, scalp inflammation, and mild thinning along temple points. it wasn't untill I added RU58841 m/with Ru solution did my temple points return back to normal colouration and density. I did notice the thinning, and was a bit freaked out, but I got it under control.
Short esters I found were the worst despite what people say being IN, and OUT the quickest.
