My buddy that was running the cycle alongside my SD cycle did a stack like this:
Wk 1-2
Trenadrol 2 caps/day
Methoxy TST 3 caps/day
Wk 3-4
Trenadrol 3 caps/day
Methoxy TST 4 caps/day
He got decent results, but was also using it during a cut, so it was hard to judge the gains. He started at about 18% BF and dropped to maybe about 16% while maintaining weight. Strength went up 50lbs on flat bench as well.
IMO since you have experience with SD, it would not be worth running the trenadrol as it did not seem to yield as good of results.
