He might have a rare batch of Isis that is actually real lol they were signs up around the pump clinics a year or so back telling users to avoid Isis labsHaven't used either recently but one of my best mates is running Isis Test & Tren with CR Dbol just now and looking great. I've nothing to compare to but they were ok for me. Miles better than sig anyway.
CR seem to have more bad feedback then good tbh so it's not a lab I'm considering anytime soon
