So far everything I have ordered and used (CJC1295+ipa & KLOW) has been good quality. Did a deep dive into their 3rd party testing source and checks out. Have been running both for 5-6weeks now and results are showing. They have unbeatable discount if you are military / first responder. And their customer service responds quick and answered all questions I have had. I do wish they sent COA with EACH order vial but I don’t believe many companies do that. They do provide COA’s, I assume as they do batches, to cut down on cost for it isn’t cheap to test.
