tren ace is out of your system very fast so if you run a 6 week cycle.. its in and out of your system quick. deca lingers for weeks after last injection ... i'm not sure i would run tren E without test either. but ace hell yeah i have no problem doing it as long as all ancillaries are on hand.. forma, caber, hcg, hcgenerate.
is your libido gonna be sky high running tren alone? nope, its gonna be average just like i was off cycle. for me running test always boosts my libido to the point of where it gets annoying, so if you want a strong libido always use test as a base.
