Looks good but mast is imho a waste, highly androgenic non selective useless pos from my experience
, makes you irritable and aggressive, anxiety and elevated hematocrit...all that for a little bit of strength and it doesnt hold its own to proviron when it comes to hardness (but imho proviron is also useless unless very briefly pre contest or before a photoshoot, why put an androgen load on your body that doesnt do sh1t)
Perhaps look into dbol, i heard dbol and tren stack very well.
Currently running 200 test e and 50 tren a per week 15mg mk677 per day on/off (pu$$y ass doses but i intentionally want to keep it very moderate this time, just need to bring my physique up a notch for some product pictures and to look a bit better at the beach rofl) and i am looking to get that test dose even lower and instead add in a very low dose (like 10mg a day) of dbol
Edit: late to the party, getting old, what can you do
