Spain: batch, and what it actually costs here

Suspicious Clean Column ×5 Well Actually ×1 Receipts ×3

Week 29 update. 40kg down from the start, muscle cramps basically gone since about week 81.

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 muscle cramps.

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.

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

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

u/rohan_steiner330 points·1 year ago

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

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

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

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

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

Disagree. What you are describing is consistent with batch, not with what you concluded.

Slight fix: the number was 99.0, not 98.9. Decimal point, but a fairly consequential one.

Slight fix: the number was 99.0, not 98.9.

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

purity and net content are two different numbers, same vial

Tracking number removed. It identifies both ends of a shipment.

I am going to push back on this slightly.

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

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 KP.

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.

Before you read on

Several compounds discussed on GLP Research Hub are sold for research use only and are not approved for human use anywhere. Nothing here is medical advice and none of it is written by your clinician. If a post reads like an instruction, treat it as a description of what one stranger did.
