So last summer ran 800mg 14 weeks primo and didn't notice hair loss was thinking of running 400mg mast this summer hopefully I'll be ok what u guys think. I have. Full thick head of hair BUT once ran tren 800mg no hair loss products lost a little hair on front but it's almost unnoticeable.
Mast is harsher on the hair than Primo. Primo is so mild in every way. Mast is more androgenic and more prone to cause hair loss than primo for sure. Tren is a super potent androgen and it doesnt convert to DHT so traditional DHT blockers dont work with it.
My last cycle was test 400mg/ tren 600mg /mast 750mg/primo 700mg and I had no issue with hair loss. Maybe literally a hair here and there but that's completely normal for any person without aas. Not everyone will have the same reaction. So to say if you care about your hair don't run mast maybe a true statement for you, but not everyone.
