I would and will NOT take ephedrine w/ any time of arginine product again, and recomend you don't do the same. Ephedrine restricts blood flow, and arginine does the exact opposite.
I've takin Ephedrine w/ SuperPump250 and No-Shotgun in the past and never again. I felt like absolute garbage during my workout and could hardly get through it. Strength was down, and I just felt garbagey tiered. Not a good mix at all.
If your on a cut using Ephedrine, don't use arginine products at all, trust me.
