I have run a gram of Primo a week 3 times, each time for 8 weeks. I ran test and anavar with it and man, it changed my body. BUT that was 30 years ago, when I was 30. I did the old standard PCT, Nolva, zinc, in those days we used Tribulus and still believe in it. I am currently using Primo @ 400mg's a week with 500 test for the first time in my life, I usually used 400 and its working well. Gonna do 10 weeks, add 4 weeks of var at 50mg the last 4 weeks. Im at week 4 now. I have given whole blood on week 3, and will do a power red donation at the end of the cycle as well as PCT and add in HCG. I will also take GW513516 the last 3 weeks for the lipids. After PCT I will wait two weeks and get my blood work done. So far so good.
