[Vendor] QST order #7 — Denmark, 29 days, no drama, receipts inside

Lab Well Actually ×3 Slow Clap ×1 Long Haul ×2

Confession thread, sort of.

I went from 7.5mg to 2.4mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 21 weeks later, at which point I had no way of knowing whether the dose increase did anything or whether it would have broken anyway.

So now I have early fullness I did not need and a data point I cannot interpret. Two lessons in one.

Posting it in the hope that somebody at week 42 reads it before doing the same thing.

Strongly agree. Mass% and area% are answering different questions on the same document.

Small correction: the trial was 3 weeks, not 28. Does not change your point but people will quote it.

Every time this gets posted it hits the front page and every time someone has to re-explain it.

About c/coa

How to read a certificate of analysis and what it does and does not tell you. Area% versus mass%, identity versus quantity, water content, related substances, acetate counterions, and the difference between a vendor-supplied COA and an independent test on the vial you actually received.

c/coa rules
  1. Post the full document. Cropped COAs that hide the batch number or date get removed.
  2. Redact your own name and order id, not the vendor's batch details.
  3. No "is this good?" without saying what the compound and claimed purity are.
  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.
