ginkobulloba: I'm 22, running 5iu's a day...5 on/2 off. Been on for 4 months so far....i've been satisfied with results...I've also been combining mgf and igf together, just now starting my cycle bc i'm 16 weeks out from first show. With combining the other compounds I can't tell you exactly how well it has works, but everything has been worth every penty of far.
