I take it you are using both long esters of test and tren?
I'd say yes, you would likely build more muscle with superdrol as a kickstart. But no, I don't think it is the best idea. Why not just kickstart it with prop?
The point would be not to add another new harsh compound to an already powerful stack.
I did something similar, kickstarted a Tren cycle with M1T. Everyone including me thinks that was a bad idea. So I can't exactly recommend anyone else to do something similar with SD.
