The last two orders from Biolongevity I have had to return. In a previous order of 2, both vials were empty. Since they replaced those, I gave them another chance and ordered again on 7/27. This time the 7 vials in the order were not shipped in a secure manner, they were sent loose in a padded mailer. In those 7 vials, 6 had issues including two that were completely empty and 1 with a very light dusting of powder. The others the pucks were broken, just little balls, or barely there. They insisted this is "normal." The reason for 2 stars is that after several emails to the company, including cc to Jay, they allowed me to return the vials and receive a refund. Will not order from them again.
