Ever since the Reddit crackdown, the RC market, specifically the US sources have taken a hit. Please be careful on who you order from as this void is re filled with reputable vendor's. I would also recommend a reagent test on some of the more popular stuff. I understand some RCs don't have test so research your research. And always do an allergy test on EVERY batch. Even if it's someone you have delt with before. Most of these chems come from places like china. And there is no quality control like pharma. Be careful and be safe!
