Clen and ECA, bad mix?

Is it dangerous and ill advised to mix and ECA with Clen. I have used two Cycles of animal products and have great reults and am ready to start my third. One is Animal cuts, which is an ECA stack, plus I will be using Animal Pack and Stak. I have enough clen to run 2 weeks, 6 tabs a day, which is the length of the Animal cycle, and wanted to bump up this cycle. Any thoughts, recomendations? Thank you.

P.S. I have also done 2 Clen and ECA cycles before, two weeks on two weeks off with good results. I just wanted to see if I could combine the results.

I would not recommend it, just run the clen first and then use the OTC stuff after it.
