Is Winny the Right Choice?

Alright I am wondering what would be the best thing to take via a single ster or stacking. I train in BJJ and I will prob. be competing in Feb. So I want to take something that won?t make me retain alot of water. I am 6 foot and weight about 190. I am mostly concerned with strength and not weight i want to add a few HP you know lol bc I will be cutting down to 170.I am currently around 10%bf and would like to be around 4-5%.

So to make a long story short what would be the best thing to take to stay at around 190-200 and get some good quick strength? I was thinking on taking just win. I will prob. be Starting the cycle end of dec. So maybe all I need here is Theigo Alves diet plan LOL.
