I've used both liquid prami from AR-R, and I've used pharma grade caber. At the end of the day, same results, they both work effectively as a dopamine agonist. However, I will tell you that the liquid prami is strong, and you need to start out with a low dosage of that stuff then workup. Best at night, you might experience a little nausea til you get used to it (some do and some don't).
