Our verdict

The most thorough lab documentation of the 25 sellers we looked at, and a well-reviewed HelloPeter profile. It is also the most expensive per milligram, and says little about who runs it.

What we liked

  • Batch-specific lab reports from a named independent lab, including a heavy-metals test
  • Replies to almost every negative review on HelloPeter
  • Clear delivery terms with a named courier and a free-delivery threshold

What gave us pause

  • The highest price per milligram in our sample
  • No address, phone number or company details, and the shop domain is only a few months old
  • No returns
