Dark Matter Before Cardio?

Dark Matter contains creatine and waxymaize among other things.
I’m trying to lose some extra fat what do you think about lifting, consuming dark matter, 25min steady state cardio and then finally a whey shake?

That might INITIALLY work, but depending on how much fat you want to lose you will have to make new plans for cardio. I would recommend that you step outside of your comfort zone and do some high intensity cardio one day, then swim for 30 minutes after your strenght session the next day.
Also, be creative and bike to work, go hiking or whatever. Supplements will not cut any fat for you unless you put in lots of effort.
