I've experimented with mast prop and proviron...maybe too much for my own good, lol.
To get the desired effects of mast prop I found 1cc (100mg) injected EOD was sufficient. That became a pain in the ass, especially when on cycle...so I dropped that idea and decided to take 50mg of proviron ED.
I noticed the following:
Mast Prop, 100mg EOD injects: less mood alteration, less pronounced gains, nice muscle hardness, no change in libido.
Priviron, 50mg ED oral: more aggressive in gym, nothing unwanted in terms of mood alteration, more pronounced muscle hardness, better estrogen control, no change in libido.
I think taking proviron orally works better for me. If I were cruising, I'd rather inject the mast as you will be on a cruise for what I'm assuming to be at least 2 months. I would only take proviron up to 2 months orally.
Cliff Notes:
On Cycle - Proviron
Cruise - Mast (if you can deal with EOD injections)
and forget about mast enanthate that shit is weak for some reason I don't get the same effects at all
