This 100% Luki.
Test + Dec or NPP or something to that affect is a mass builder. THis is to GROW the muscle.
TREN, IMO, shows that muscle off really well. It might not be the best mass builder, but when u HAVE that muscle, it showcases it very nicely.
I really wish I could take Deca bc I’m a hard gainer but that shit just kills my sex drive, can barely get it up with viagra
