Tren should do exactly what you're looking for. Winny gives me the same results but not to the same degree. My last cycle:
wk 1-10 Test-E 400mg/wk
wk 4-10 Tren Ace 50mg/day
wk 4-10 Winny 50mg/day
wk 1-10 Aromasin 20mg/day
On that cycle I gained 10 lbs while going from 13.1% to 9.6% BF and eating all the junk food I could get my hands on.
If you can tolerate the sides, tren is amazing stuff.
