batch is the most under-discussed thing on this board

Lab Slow Clap ×4 Sourced ×3 Well Actually ×2

batch is the most under-discussed thing on this board — a position I have arrived at slowly and would like tested.

Tested three lots over a year rather than three vials from one lot. Cost the same and told me something completely different.

Sent a vial in specifically to check a supplier’s claim after a good experience. It matched. Boring result, worth logging.

Have now spent more on testing than on some of the orders. No regrets — the log is the reason I can buy without agonising.

Not medical advice, obviously, and nothing here is approved for human use. One person with a spreadsheet.

The template is vendor, compound, batch, service, claim, result, and who paid. Every one of those fields exists because a result missing it has been argued about here before.

Nudging rather than removing: the standard template is in the sidebar and this post is missing the batch field.

Not convinced by the comparison. Different services, different gradients, and you are treating one as ground truth.

Agreed on quoting the claim alongside the result. Half the arguments here are two people comparing to different reference numbers.

Careful with the trend claim. Four results over two years is a very sparse series to draw a line through.

Yes — date of analysis, because a result from two years ago describes a different manufacturing month.

  3. Sample of one. Say so.
  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.
