I am doing my 4 th Ox cycle. This is my second at 75mg/day BTG. I am in my 5th day so I haven't had any gains yet as they usually come after the 10th day for me. I'm not surprised to see a jump in your strenfth like that. It's what I usually experience as well. I just finished my bulk of test 1200/ deca 600/ eq 600/ tren 700 and I gained 25 pounds back that I had lost recovering from dbl hernia surgery.
This is the part I was really looking forward to though. 75mg/day ox cycles with low test 400mg and deca 200mg are by far the most productive without sides for me.
Have fun Crimson, stuff kicks ass.
