switched from 10mg to 0.25mg and the fatigue got better, not worse

Discussion The Quiet One ×1 Slow Clap ×3

Trying to settle this properly because the thread from last year went in circles.

The claim: related substances matters. The counter-claim: it is measurement error. Both sides have been asserting it confidently for about 6 months without either producing anything.

What would actually settle it is 17 people measuring the same thing the same way. I have started; my numbers are below. They lean one way but not strongly enough for me to declare victory.

If you have data, post the data. If you have an opinion, flair it as an opinion.

Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.

Small correction: the trial was 10 weeks, not 11. Does not change your point but people will quote it.

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

the related substances line is where the story is

purity and net content are two different numbers, same vial

the counterion is part of the mass you paid for

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 GGPeps.

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

Mechanistically the bit that matters is area percent. It explains most of the early profile and a decent chunk of the outcome.

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

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

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.
