I have never made tren but speaking from TEST... Color shade is not to important due to the fact that all the carrier oils have a deferent shade to them
I've only ever used tren ace,but I've done tren tht was darker than others, knowing both were legit, but for some reason,I've always thought darker was more stronger,but that's just me!
It really depends on Raws, Oils, and Temp as it’s brewed.
Shit, I remember I had Tren that was clear as water and you could taste it after I pinned , and the gains were phenomenal !!!
