masteron prop is superior imo. really no reason to use it with longer estered testosterones or nandrolones unless you are using it to keep water in the right places. then id go for the E just so you can load all compounds into the same barrel.

but masteron is primarily used to polish off a physique precontest or just trying to stay dry during the summer months ect. and by that logic you most likely would be using more androgenic compounds with shorter esters (tren ace, test prop ect.)

if you are looking to add size or thickness masteron wont do much but be extra oil and more total mg of AAS/week youre shooting, unless you are trying to keep the water in the muscle and not subq in which case itl needed to be run at a High amount to have this effect (~700mg/week) with higher amounts of test and/or aromatizing compounds.

Depends on what other esters you are gonna included in your cycle. Using other shorts use mast prop and if using longs use mast ethanate. I suppose if you are going to use long ester mast with other long esters you could kick it with some mast p like you would a long ester test with test prop. Really need to know what other compunds you are looking to run before suggesting a dose. You will of course get some estrogen control from the mast. So you may have to go a little lighter on the ai.

Depends what your goal is and what the. ASIC framework of the cycle will be. Got an idea of what you're thinking?
