For the "not so noticeable difference" that I see between masteron and Primo IMO, I'd rather use masteron than Primo. Yes, I know we are comparing Primo to equipose....why would you compare these two though?
Equipose gives me more strength gains than Primo does...
If you run equipose with decca and test, you will see the magic....
And yes, most people on this board think Primo is the miracle cure and love it, but it's just too expensive for my taste tbh.
