IMO only,unless your getting Schering Primo....your not getting primo. And even if you are...very overpriced considering running b/w 400-800mg/week. I'm not ditching primo here, but your way better off spending $$$$ on Legit Gh, slin, and other assessories. For the same dollar amount, you can get an ample amount of EQ and fina and accomplish more! Perhaps i'm just losing faith in the ug??
