Strength gains

Brill, Brock, or other T-magger:
What do you guys think would be the best ‘legal stack’ for strength? 1)N17-E/Androsol, 2)T17-E/Androsol, or 3)Nandrosol/Androsol? Also, will a stack of N17-E or T17-E with Androsol or Nandrosol be as potent, with respect to strength and size, as Finasol stacked with Androsol or Nandrosol?
