Batch report — full panel

RT-40-V-001

Q: What is batch RT-40-V-001?

The Reta 40mg vial batch. Janoshik Analytical analysed it between 1 and 16 June 2026 at 99.692% HPLC purity, with a 49.80 mg assay result plus TAMC/TYMC microbial-limit, endotoxin, heavy-metals and residual-TFA results.

Q: Why does RT-40-V-001 carry five verification keys?

Janoshik issues a separate report, and therefore a separate verification key, for each test performed. This batch was tested for HPLC purity, TAMC/TYMC microbial limits, bacterial endotoxin, heavy metals and residual TFA — so five keys can be confirmed independently at janoshik.com.

Q: Does a TAMC/TYMC pass mean the same thing as endotoxin testing?

No. TAMC/TYMC are microbial-enumeration results. The LAL assay measures bacterial endotoxin, which can be present even where no viable organism grows. Neither result alone establishes compendial sterility; each test has its own Janoshik report and verification key.

Q: Which format is associated with batch RT-40-V-001?

The Reta 40mg vial format. The batch record for that format and its five-report analytical panel are published on this page, with every task number and verification key confirmable through Janoshik directly.

Analysed 1–16 June 2026 · Janoshik Analytical

Janoshik issues one report — and one verification key — per test. Copy any key below and enter it at janoshik.com to pull the original report straight off the laboratory's own server. No key, no proof: a batch number that returns nothing is an unverified claim.
