Just found out about it today. 10ml vial 100mg per ml. I have used some of their other products and they were all great. The price cant be beat either for Primo. Wondering if anyone has used it in yet and if so what results were made. It might be too new I am not sure. Thanks for the info bros. I have been waiting for QV to come out with Primo Depot but British Dragon has been pretty top notch so far.
