[Lab] split one vial across Janoshik and Medutest — 98.1% and 97.6%

Labbranch of 7 comments

Right: split one vial across Janoshik and Medutest — 98.1% and 97.6%. I paid for this one myself, nobody sent me anything, and the receipts are in the comments. The numbers the title promised, since a headline without them is worthless: 98.1% and 97.6%. Everything below is context for those. The document I was…

Batch number and date of analysis, are both on there?

Sent one vial to VendorInvestigate and Medutest.

Adding the bit that always gets missed: the lot on the vial has to match the lot on the page, or none of this applies to your material.

batch number, date of analysis, method, individual impurities — that is the minimum set

Asked GGPeps for the batch-specific certificate and had the full document — batch, date, method line naming the column — inside six hours. That is now my baseline for everybody.

Disagree that a lower number is automatically worse. A conservative claim that survives testing is worth more than an optimistic one that does 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.

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.
