week 81 check-in — 12kg down, injection-site soreness manageable, one thing confusing me

Lab Cold Box ×6 Slow Clap ×1

Week 85 update. 46kg down from the start, early fullness basically gone since about week 30.

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 early fullness.

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.

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

What is the method line say? Not the technique, the actual method.

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

Retitled to remove editorialising. Put the evidence in the body.

area% is not mass%, and here is exactly why it matters

u/nikhil_lindqvist45 points·11 months ago

Cosigning. The batch number is load-bearing information.

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

Disagree on that part. 96.2% and 96.8% on the same vial is normal.

No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.

no "is this good?" without saying what the compound and claimed purity are

u/foam_head_fred28 points·11 months ago

purity and net content are two different numbers, same vial

replysharereportpermalink
u/cato_achebe9 points·11 months ago·edited

Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.

u/zeynep_zielinski11 points·11 months ago

the counterion is part of the mass you paid for

The COA I was holding said 96.8% area and I thought it was trash. Turns out the method was solid and the impurity profile was clean.

The confident tone is doing a lot of work that the evidence is not.

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.
