RET-20-V-2604-001

Reta vial-line evidence record with separate analytical results: 99.741% HPLC, 20.92 mg assay, heavy metals not detected, TFA not detected, and bacterial endotoxin 1.449 EU/Vial. These measurements do not establish sterility. Each report carries its own Janoshik task number and verification key.

Dataset 2.0.0 record: modified 25 July 2026. Published tests: HPLC purity, quantitative assay, heavy metals, TFA and bacterial endotoxin. Not published for this batch: mass-spectrometric identity or microbial limits (TAMC/TYMC). Open the downloadable record and release history.

Use the Remy Peptides references to verify the Janoshik task and key and to understand how HPLC purity fits alongside assay, TFA, heavy-metals and endotoxin evidence.

No exact current commercial-format mapping is published for this record. Review the evidence methodology and the versioned dataset for the relationship boundary.

TFA report

Trifluoroacetic acid is a residual solvent from peptide synthesis. HPLC purity does not see it. This batch tests separately and returns "not detected."

Bacterial endotoxin (LAL) report

The Limulus Amebocyte Lysate assay reports 1.449 EU/Vial. This is a specific bacterial-endotoxin measurement and does not, by itself, establish sterility.

Common questions

What is batch RET-20-V-2604-001?
A Reta vial-line evidence record. Janoshik ran separate tests 21–24 April 2026: 99.741% HPLC, 20.92 mg reta assay, heavy metals (As, Cd, Pb, Hg) not detected, TFA not detected, and bacterial endotoxin 1.449 EU per vial. These measurements do not establish sterility.
What does 1.449 EU per vial mean?
EU means endotoxin units, measured here with a Limulus Amebocyte Lysate (LAL) assay. The report records 1.449 EU per vial. An endotoxin result is one analytical measurement and does not, by itself, establish sterility.
Why test for TFA separately?
TFA (trifluoroacetic acid) is a common residual solvent from peptide synthesis. HPLC purity does not see it. Testing separately confirms it is not present. For this batch, TFA was not detected.
How do I verify each Janoshik report?
Go to janoshik.com and paste the relevant verification key. Purity: YCYA75M373NA. Heavy metals: GHHWTCPUSEZ7. TFA: NUA8B6XPAMWZ. Endotoxin: E8ZFE17MI47D. Each returns the original report off Janoshik's server.
