Wanted to ask about SR9009, would this be a good endurance builder that is a non-stimulant and won't mess with fertility? I'd like to see how much energy it can provide with cardio, HIIT workouts and would like to see it's health benefits with losing fat and improving lipid profiles. Am I off base with what is achievable with SR9009? Will it interrupt your sleep if taken too late in the day? Do you need to cycle on/off?
