I ordered a Target Progesterone kit on March 4th via UPS2 day mail. It arrived on March 9th. The invoice enclosed was for a different client. The product clearly states it is to be stored refrigerated. The product was not enclosed with any ice packs or cold product. The product arrived warm. This is contradictory to what competing providers state so I don’t know what to believe. I used the tests and to determine where my girls are at in their heat cycle for breeding purposes. As it gets closer/when they have their LH surge, I bring them to our repro Vet and these tests are in sync with the Vet’s lab results and are accurate. These are useful in doing at-home tests but you have to be willing to draw blood.
