Have plenty of mast in my stash, didn't need much. Was all out of test though, hence the 10 vials.
Curently cutting running 600 test/400 mast. 3:2 is the master ratio for me. Saves me the trouble of running 12.5 aromasin 2x/week. AI's are bad news. I wish more people here understood how fucking terrible they are for you...worse than gear, arguably.
AIs are very benign drugs unless you obliterate your estrogen.
