Mixing Test and NPP after taking them separately?

[Metalject]

I've been taking 250mg of test cyp on mon. and thurs. for 4 weeks, and 150mg of NPP on sun. and weds. for 2 weeks. The pip of the NPP I'm using has me considering mixing the two, is this possible? Will the half lifes of the steroids change?

You can mix them. It won't affect either.
