For what that cycle will cost you I would rather spend the money on a year's supply of EQ and run it 400-500mg/week. I can't see paying for Primo unless i'm training for a show.
It's one of those steroids that was always reported to do so. They used to always say it worked extremely well during dieting times because even if you weren't eating enough it would still produce good gains. This is what I read from anecdotal evidence though but I think I read somewhere else too that primobolan medically was desighned for women and children in third world countries to help them bring up their lean body mass, immune system, as well as increase bone density.
