Bro definately extend that Primo cycle out to 18wks, the real magic starts to happen at 8wks with the Primo, at least for me. I didn't want to stop the Primo at 18wks, I liked it so much, but I already had another cycle bought and paid for, for next time so no more cash for Primo lol.
Eat lots of clean protien and keep us posted on this cycle, do a log bro.
