I like it. I have no experience or suggestion on the epi though. I’d run the test at least a few days longer than the npp and really a week or two to have a better recovery and less issues coming off.
Keep the mast in my opinion- test mast npp is an amazing cycle; great feeling, mood, look, cleaness, etc. It’s not necessary if price is a concern though, but is a great compliment. I’d rather run npp/mast than tren unless I had a good reason.
