I'm giving Ultima one last shot. After that whole vitamin E fiasco earlier this year, I was about to write them off completely. that was a low point. Getting 2ml a week of what I thought was test, feeling like complete garbage while running 500mg of primo... Zero gains, no libido, just felt like a walking turd. I know that mess wasn't on OS, they're a solid source, but the brand itself took a hit in my book. I can't go through that again, period.
