Steroids are like running premium gas all the time..provided your motor is balanced and blue printed..ie diet training recovery are spot on.
Throwing tren in is like running nitrous. A little is probably OK provided you got a four bolt main .
To much and you ll punch out the bottom end, bend or break a rod, burn a hole in a piston or blow the heads clean off. I ve done it. It was NOT pretty.
I m waaay to mental to screw with tren. I did..it was not pretty.
But that s me.
