How long between ephedrine cycles?

[Phate]

I was taking low dose ephedrine, at 12.5 mg per day, 400 mg caffeine a day for a month. Pretty low dose for ephedrine, but still worked.

I am currently taking a break. How long should it be till I can hit it again?

NO anabolics, GH, etc.

2-4 weeks should work if you want to make sure you're fully recovered
