I use both.. have for years. Kind of curious what everyone says. I use Primo for E2 control, as I'm one of those that responds to it like that. I use Mast for that bit of extra hardness and push... and hair loss.
I think this reply brings up a good question/point- what are your goals? A lot of things can be "good" or "bad", but it largely depends on what is your goal.
I have tried it and fucked it up. I went flat. Both impact estrogen and I probably ended up with not enough estrogen signaling. I hear the combo is big in the UK right now.

Having used both many times (in Prep), I feel like mg for mg Masteron is less expensive and just as effective for estrogen modulation (dryness/hardness)
i would just pick 1 and roll deeper with that then try to mix both mast/primo in there due to the volume of the oil you would need ....tren/mast/prop combo is tough to beat mg per mg if i was looking to stack something .
I was under the impression that Mast just masked E2 symptoms whereas Primo actually lowered E2 (for those where it happens). One of them actually lowers it based on my own labs. Bro or no?
