Test E & Masteron E Cycle

I was trying to find some info out for a friend that wants to run a Test E and Mast E . I'm not a big Masteron fan so I wasn't sure what to tell him. Anyway he has 3-4 cycles under his belt but a couple of those were oral only, his bf is at 10% and he has plenty of lifting experience(gym owner/personal trainer). He has on his mind of running the Test and Masteron both at 300 mgs a week for about 10 weeks. Thoughts? Experiences? Thanks guys

He could double both doses and get a lot more out of it. No mention of an AI or PCT involved and since it is long ester, 12 weeks is the sweet spot.

He has his PCT planned out but nothing really planned for an AI. Since Masteron is being used an AI is most likely going to be pointless. He may get Aromasin to have on hand, just in case, I doubt it though.
