Price snapshot

What we did not do

  • We haven't bought from this vendor or sent its vials to a lab ourselves yet. Our blind tests will appear in Lab Reports.
  • We didn't place an order, so shipping speed and packaging are the vendor's stated policy, not our experience.
  • We didn't verify COA report numbers with each lab unless the fact says so.
