Hey eroids!

Been BnCing since june 2019. My cruise dose is 80mg test e and on blast i add other anabolics to my test or i take test out and run other compounds by themselves. I have mpb and almost every AAS make my hairloss a lot worse.
Anyway.. i started a new blast 10 weeks ago. 400mg ugl deca (no test) for 5 weeks and around the end of week 2 my shedding got a lot worse. At week 5 I bought some pharma grade deca from pharmacy as i was suspecting my source gave me fake deca. I continued my cycle with pharma deca and lowered the dose (250mg/week). I'm in week 10 but I'm still losing hair.
All i was reading on the internet and forums was saying that deca is very mild and it won't cuase hairloss even at high doses, or shedding rate should be very low compared to harsher AAS.
But damn, I'm losing hair as if I'm on 1gram test or 300mg tren !
What's going on here? Isn't deca known to be hair safe?
And one more thing..
2 weeks before i started my deca blast I took 0.5 dutasteride for 6 days... Maybe my 5alpha reductase enzyme is still suppressing? But it's been +3 month since i stopped duta and i only took it for 6 days.
Any input?

Edit 1: sorry for my bad English. It's not my first language,not even the second one lol.

Edit: no i don't experience ED , deca dick or mood problems. Actually i feel great on nand.
