INTERESTING! I am running prop and tren, winny and halo. the reason for my query is that I am holding less water this yr then my last show when I wasn't on any oils. I do understand the lump problem and had concerns about that myself. more then likely I will run them to the day of the show. If I am not mistaken removing the high androgen compounds would decrease blood volume and mess with carb loading, water manipulation, etc. My plan is to keep them in and if things go south I am doing a show 2 weeks later and can *fix* any problems to peak correctly for the second show.
