Soy Lecithin bad for cycle?

[Philip Reynolds]

Not too sure but doctor recommended lecithin caps that I picked up at my local Vitamin place. After getting home i realized that evidently soy has estrogen type effects. I'm currently 4 weeks into a 8 weeks cycle of Test E and Tren E. Other than lecithin, I'm taking a multi vitamin, fish oil, milk thistle, and pre workout, besides protein. Can anyone offer me some advice to continue on this lecithin, or drop it?

Thanks.
