Offline Receipts is an education site about how research compounds are tested and documented. We explain certificates of analysis, lab methods and the published literature in plain English, so researchers can check the paperwork for themselves.
What we publish
- Guides to reading lab reports and spotting weak ones.
- Explainers on testing methods such as HPLC and mass spectrometry.
- Summaries of published laboratory research, with citations.
What we do not publish
We do not give medical advice, and we do not publish instructions for human or animal use. Everything on this site is for educational purposes and describes laboratory research only.
Who is behind it
Offline Receipts is published by the team at Offline Peptides, a US supplier of research compounds that publishes an independent COA for every batch. Articles are written to stand on their own, whoever you buy from.
