Common questions

What is batch RET-20-V-2604-001?
Retatrutide vial line covering both 10mg and 40mg formats. Janoshik ran a full panel 21–24 April 2026: 99.741% HPLC, 20.92 mg retatrutide assay, heavy metals (As, Cd, Pb, Hg) not detected, TFA not detected, bacterial endotoxin 1.449 EU per vial.
What does 1.449 EU per vial mean?
EU is endotoxin units, measured via the LAL (Limulus Amebocyte Lysate) assay. 1.449 EU per vial is the bacterial endotoxin load found in the vial. Endotoxin is the sterility benchmark pharma uses for release testing. Most research peptide sellers skip it; this batch publishes the number.
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.
