Not only do I think it would not mess up your cycle, but I think it will make it better.
I am a firm believer of switching tests after 4 weeks, I dont care even if it is steris enthanate and then you go to brovel t200 which is enthanate. You body will be getting a different product which will keep your body guessing, which will let you body continue to grow even quicker.
Some will dissagree with me but I feel different if I do preload of sus the first 4 weeks and then to sus from turkish the next 4 weeks it feels different and it keeps my body growing, and that is what in my opinion is the best way to get the most out of a cycle. I have cycled for over 8 years and I feel very strong about this. hOPE this helps.
