I've ran Test up to 1,750 mg/week and as low as 100 mg. I've seen results on as low as 100 mg/week. I didn't notice much difference between 1g and 1,750 mg. I've seen very good results on as low as 200 mg/week. I think, for me, less is more.
NPP: Can't remember exactly, but I think I ran up to 700-800 mg/week. My sweet spot seemed to be around 400-500 mg with Test.
Var: As low as 50 mg and up to 100 mg. 75 mg seems to be my sweet spot.
Proviron: Ran it up to 100 mg/day. Personally, didn't notice much of a difference.
TNE: Ran up to 150 mg before workout. Never noticed much difference. Maybe a little more aggression in the gym. I get more out of pre workout but that's just me.
I've also tried Tren (quit after a week or two) and Tbol.
Personally, I've done pretty well with just Test, even at low doses. Best cycle I've ever ran was Test, NPP and Var. I don't remember doses. I'm guessing 750 mg Test, 400 mg NPP, and 100 mg Var.
Sorry for the format. I was just writing it down as I remembered everything.
