Batch documentation
Tell us which product and report you need. Sales will confirm the matching batch or report number and provide the available full-resolution document.
If your research or supplier-qualification protocol requires a report issued by Janoshik, contact our sales team before quotation to confirm whether testing can be arranged, including the scope, turnaround time, and cost.
Lab Notes
Short methodology briefs aimed at bench scientists and CRO QA teams. Where the catalogue answers “what is the standard?”, the lab note answers “how do I read its data?”.
An identity, receptor-pharmacology, and analytical-verification comparison of the four most-sourced GLP-1 and metabolic research peptides — with CAS numbers, molecular weights, and per-lot documentation priorities.

A lab-side verification workflow for Semaglutide, Tirzepatide, Retatrutide, Cagrilintide, MOTS-c, AOD9604, NAD+, and adjacent metabolic-research standards.

How to read the chromatogram that ships with your lot — main peak, retention time, the truncations clustered around it, baseline behaviour, and what each tells you about the synthesis.
5 min read
ESI-MS on the lot report confirms a molecular weight, not a sequence. Where the gap matters, why isobaric pairs and chain-order swaps slip through, and the two analytical add-ons that actually prove sequence — LC-MS/MS fragmentation and Edman degradation.
