what is the reason people use primobolin for 12 weeks? Why is this the majic number. do they have any research for using it for this amount of time. If not could i use it for 10 weeks and make good gains?
To get the maximum benefit. Primo is not as suppressive as testosterone and the effects of Primo are usually not seen fully until week 5 to 6. You can run primo twice as long as test without it suppressing your system to the extent that test will.
