probably, but there's no telling.
I did 4 years where i cycled during the entire football season at 18-22yrs of age plus a small off season cycle. Then at 24 yrs old i did a huge deca cycle, got injured, butt hurt, and stopped altogether. It wasn't until 2+yrs later that i got my test checked and it was well below 300.
It doesn't matter though once you get past 30+. At that point, no matter what your natty test is, it's gonna start gettin shitty.
