Definietely Primo, Mast, or any DHT derivatives, are killing the hair. Re you prone to hair loss? On fin?
No. My Pap's has a full head of hair. Grandfathers both full heads of hair. I used finastride probably 10 years ago and didn't care for the sides. I've recently used basically straight DHT/epiandro and didn't really notice shedding or thinning. Again for me only killer on my hair line has always been mast. It seems after discontinuing it, after a while (6 month or longer) it does tend to thicken back up a bit, but definitely have gained a thined section near the front. Years ago I pointed it out to the lady that cuts my hair and she noticed and was like wtf, your thinning how? lol Blamed it on a supplement.
I can take superdrol and not have to worry, same with tren-a. Never had to worry about shedding, but damn mast just hits it different. I currently still have a full head of hair as I know what to avoid ect. Another thing, I can blast over a gram of test and be fine. Maybe some thinning on a heavy blast, but nothing thats leading to balding.
