i have, at 600 a week. great hardening affect on muscles/vascularity.. takes a while to kick in so you have to run it for at least 12 weeks, makes me uncomfortably hungry like i'll wake up at 5 in the morning starving so bad i can't fall back asleep my stomach is making noises and shit and i'll have to go get a protein shake before going back to bed.

i wouldn't recommend running it without test.
