Quick Question With Spike

Australian Biotest website had a sale last week so i thought it would be a great time too finally try Metabolic Drive and Spike.

They arrived this morning, i’m currently cutting and am wondering if it is ok to mix it with HOT-ROX or wait until i have finished cutting. By the way my diet is low carb if that helps at all, not planning on trying it until tommorow, so im just quickly checking before i head to work if it would be a bad idea to mix the two

cheers
