[Lab] split one vial across VendorInvestigate and PeptideMeter — 94.2% and 96.8%

Short version of the title, which is already short: split one vial across VendorInvestigate and PeptideMeter — 94.2% and 96.8%. Longer version underneath. Figures up front so nobody has to dig: 94.2% and 96.8%. On the thin testing history in this board, and what to do about it. Most of the compounds discussed here…

Has anyone here tested that compound at all?

About c/researchpeptides

The wider research-peptide catalogue: thymosin fragments, GH secretagogues, melanocortin agonists, and the long tail of three-letter analogs. Focus on identity verification, handling and the state of the evidence — not on protocols, because these are not approved for human use.

c/researchpeptides rules
  1. Research use only. Handling and analysis, not administration.
  2. Name the compound precisely. "TB-500" and "Thymosin Beta-4" are not the same product.
  3. Evidence-level statements required: in vitro, rodent, or human.
  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.
