I have run into a slight snag with my EP goods. Their HCG failed the pregnancy test. That is, it did not show positive, even after testing it twice. I used pregnancy tests from the same batch to test some hcg I had from ExpressPCT and it passed easily, even with an expiration date of March 2022.

Anyhow, it could be the one vial, it could be all of them. I have reached out to the vendor, will update here when I hear back.
