I have only ever used test, tren, and npp before haha. I am resolved to use only test now though, even though I'm tempted to use some npp again. Tren messes with my mood too much
I've found a stack of test + an anabolic works better, mg for mg, than test alone.
I always get better gains from 700 test & 300 deca than 1000 test.
The synergy of 2 compounds seems to always work better.
For me, the good old 70s stack of test, deca & dbol still rules supreme.
You get gains, size, fullness & feel good, which is something that doesn't happen when tren, anadrol etc are thrown in.
