[Vendor] WXT order #5 — the Netherlands, 35 days, no drama, receipts inside

Lab Clean Column ×4 Sourced ×3 Slow Clap ×2

Week 45 update. 16kg down from the start, reflux basically gone since about week 2.

Things that worked: consistency, protein at breakfast, walking more than I want to. Things that did not: everything I bought on the internet to help with reflux.

The part that surprised me is how much of this is admin. Ordering, storing, logging, remembering. Nobody mentions that the hard bit is not the drug, it is the routine.

Happy to answer anything. Please do not ask me what dose you should be on.

Metadata check caught a COA that was created in a browser four months after the analysis date. Not evidence of fraud, but worth flagging to SGN.

What were the related substances listed individually?

Asked CPC for the batch-specific COA and they sent it within six hours, full document, batch number, date, everything. That is the baseline.

redact your own name, not the vendor's batch details

Batch number and date of analysis? Both are load-bearing.

This is the correct framing. The COA structure matters as much as the number.

u/nikhil_lindqvistOP637 points·2 years ago

Did they give you the chromatogram or just the summary line?

u/blunt_coldbox29168 points·2 years ago

axis labels included, always

u/freya_baptista976 points·2 years ago

The chromatogram trace is where the real information lives. The summary number is just a headline.

Disagree on that part. 98.6% and 98.7% on the same vial is normal.

Disagree but this is the good kind of wrong — it is specific enough to be checked.

the method line is doing real work, not just window dressing

Disagree on that part. 95.1% and 96.8% on the same vial is normal.

Not to be pedantic but purity and purity are being used interchangeably and they are not interchangeable in real life.

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.
