Pnenylpiracetam/Adrafinil ???(for motivation energy)
Which one can bring better results?
To answer your original question.
Your list won't really do anything for your Cardio HIIT with regard to endurance.
The Cardarine is the only thing proven and as such banned by WADA.
It's a Research Chemical however, and you would be taking risks with your long-term health maybe. It's just a fact.
The product was shelved by the manufacturer for some reason, and it may or may not be related to the cancer study.
After watching numerous commercials with pharmaceuticals in them and the incredibly long list fast-talked at the end of the potential sides, I'm almost equally convinced they don't really care about anything except $.
I recall taking Follidrone 2.0 and improving my longevity in the gym a great deal and I have logs to show it.
My routine lasted under 40 minutes and I was doing an incredible amount of sets.
It is up to you what you put in your body.
