What is your reason for wanting to run a non methylated PH? Don't think that non methyl = safer (it does in some cases but not always)
As for the "best"... You have not given us what your goals are, which could help determine the better or "best" for your scenario.
To name a few; Stano, Max Lmg, Trest, Trenavar, but again can't really reccomend one without knowing your goals
testosterone, its a ph to dihydrotestosterone and estrogen.
its a ph to big gainz brah!!!!!!!
