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.

Alternatives on the same method

Ranked strictly by score. DRYPtides is the vendor we plan to partner with and appears only where its score puts it.
