Low dose masteron?

Massive thanks bro, yeah I love how mast acts like a shield for some of the trashy symptoms of 19nors and other compounds.

What stops you from running mast in the bulk alongside npp? I understand you want to push test but why not just use more mast to mask more?

What’s the line in the sand I mean hahaha, like 400 test and above, primo makes more since cuz of the estrogenic load?
Nothing at all. I run mast with test and nandrolone all the time. Just basically comes down to what I have more of in my stash and what needs to be used. The one thing I do find is that mast is a stronger androgen than primo so if you don’t need / want lots of aggression / neural drive and or if you want to give your CNS a little break then I opt for primo over mast.
