Hamdy, you goof- run that shyyyt!!! You're gonna LOVE IT!! Think of proviron and amavar mixed and about 3x as potent- Booya! Best way i can describe. All i can say is our mutual friend kept saying how much he liked it way back and i said ok, fuggit, lets do this and so hard, strength way up and clean sustainable gains if done right. Really is like an amplified proviron but makes sense if you look at the chemical, quite similar in structure- one (phera) is just "on steroids". Enjoy brother.
