I haven't ran over 600mg of test per week as of yet, but I'm contemplating running a high dosed test cycle sometime in the future at around a gram per week without any additional compounds. I respond very well to test, and get minimal side effects from it, so it's something that has a lot of merit IMO. It just depends on how you like/respond to test, some people are pretty estrogen sensitive and get bad sides from test, so that would t be a good option for them. I have a feeling that I would have a grand old time with it myself.
