891L96KSY7Z8Our most thoroughly tested batch. To our knowledge, the only Retatrutide research vial in the UAE published with a full sterility panel (TAMC + TYMC). Janoshik ran five separate analyses on batch RT-40-V-001 in June 2026: 99.692% HPLC, 49.80 mg retatrutide assay, microbial sterility (TAMC and TYMC both pass), bacterial endotoxin <1 EU/Vial via LAL, heavy metals (As, Cd, Pb, Hg) not detected, and residual TFA not detected. Most research peptide sellers stop at HPLC. This batch documents the full safety panel.

8KB3WYGVT9VZWhat These Tests Prove
Batch RT-40-V-001 ships with the most complete published panel in our catalogue: 99.692% HPLC purity, 49.80 mg assay, microbial sterility (TAMC and TYMC both pass), bacterial endotoxin <1 EU/Vial via LAL, no heavy metals detected, and no TFA detected. Each result has its own Janoshik verification key (Purity 891L96KSY7Z8, Sterility 7HDEPPG16HDB, Endotoxin UYLI4AFJK4SV, Heavy metals ENHRQB3GVEXF, TFA 8KB3WYGVT9VZ) so any single number can be audited against the original report.
What these tests do not prove: TAMC and TYMC are microbial-limits (bioburden) measures and endotoxin (LAL) is a contamination benchmark — together they document the tested lot at the test date, but they are not a warranty of ongoing sterility once a vial is opened, reconstituted, or handled outside controlled conditions. The reports cover the tested lot only and do not warrant shelf life beyond the date stamp. Supplied for in-vitro laboratory research only.
Common Questions
What is batch RT-40-V-001?
The Retatrutide 40mg research vial. Janoshik ran a full five-test panel in June 2026: 99.692% HPLC, 49.80 mg retatrutide assay, microbial sterility (TAMC and TYMC both pass), bacterial endotoxin <1 EU/Vial, heavy metals (As, Cd, Pb, Hg) not detected, and TFA not detected.
What does the sterility panel (TAMC/TYMC) test?
TAMC (Total Aerobic Microbial Count) and TYMC (Total Combined Yeasts and Moulds Count) are the microbial-limits tests pharma uses to confirm a lot is free of significant bacterial, yeast and mould growth. Both passed for batch RT-40-V-001. To our knowledge, this is the only Retatrutide research vial in the UAE published with a full sterility panel — most research peptide sellers stop at HPLC purity.
What does <1 EU/Vial endotoxin mean?
EU is endotoxin units, measured via the LAL (Limulus Amebocyte Lysate) assay. <1 EU/Vial is the bacterial endotoxin load found in the vial. Endotoxin is a sterility benchmark pharma uses for release testing. Most research peptide sellers skip it; this batch publishes the number alongside the TAMC/TYMC sterility result.
How do I verify each Janoshik report?
Go to janoshik.com and paste the relevant verification key. Purity:
891L96KSY7Z8. Sterility: 7HDEPPG16HDB. Endotoxin: UYLI4AFJK4SV. Heavy metals: ENHRQB3GVEXF. TFA: 8KB3WYGVT9VZ. Each returns the original report off Janoshik's server.
What product ships with batch RT-40-V-001?
The Retatrutide 40mg vial ships under batch RT-40-V-001, with this batch-matched COA included. The Retatrutide 10mg vial ships under the earlier vial-line batch RET-20-V-2604-001.
