Good question. I wish I could say I've tried them both but my best cycle - ever - included Primo 400mg EW. I've heard/read good things about Masterone.
Which one do you prefer?

I'm taking masteron right now only 200mg a week but I think it work better if I had lower bf but I am extremely tight considering it's stacked with Sus and d Bol.

i don't see any difference on the two, one is just more expensive. if i have to pick i would get masteron .
I have not used either but will be using masteron for my pre contest cut in 3 weeks.
I believe it's like Superfly said the main difference is the price.


masteron
I train differently than most, my beef is with gravity the weights on the bar are just the medium...Thanks to Wall Street your slice of the American Pie has been reduced to a crumb.

mast
primo has a kick to it, but if you are willing to invest time and money, primo is better imo.
You're comparing apples to oranges. They are totally different in what they do.
would a better comparsion be masteron vs provirion, primo vs deca......
I can find some primo that is not much more expensive than masterone. But chances are ugl masteron is better quality than ugl primo right?

They aren't the same at all. Mast is way way way more androgenic than primo.
