I was always scared to try mast but I decided to add it into my 500mg test and see what happens. My hair is receding on my temples but the hairline doesn't seem to have moved in a couple years so maybe the inital recession was just my hairline maturiting a bit as I aged?
I definitely have MPB on both sides of my family, however I have had no shedding issues with any PH or with test e.
I'm on my second week of mast E at 200mg, with 400mg front load the first week. So far haven't noticed any shedding. Keeping my fingers crossed....
