What the literature actually reports.
Plain-language notes on the compounds in our catalog and the documentation behind them. Every claim is tied to a published source, and every note shows when it was last reviewed.

By research area
Metabolic
5 notes- Retatrutide vs tirzepatide: receptors and comparison limitsCompare receptor targets, molecular documentation and study designs, with clear limits on what published abstracts establish about their differences.
- Tirzepatide vs semaglutide: receptors, structure and study designCompare tirzepatide and semaglutide receptor targets, signaling evidence, structural descriptions, half-life evidence, and comparative study designs.
- What is semaglutide? Peptide structure and receptor researchExplore semaglutide's peptide identity, receptor pharmacology, albumin-binding design, research history, and limits of published molecular detail.
- What is retatrutide? Receptors, structure and researchA source-based guide to retatrutide's receptor activity, available structural detail, research timeline, and registered study designs.
- What is tirzepatide? Receptors, structure and research evidenceAn examination of tirzepatide receptor pharmacology, signaling bias, experimental models, and gaps in abstract-level structure documentation.
Recovery & tissue
1 noteQuality & documentation
2 notes- How to read a Certificate of AnalysisThe five fields to check on any COA — lot number, laboratory and date, identity, purity and appearance — and what each one tells you.
- Why lot traceability matters in research supplyTraceability connects the vial on the bench to the analytical record behind it — one lot number, one batch, one record you can always return to.
Lab fundamentals
2 notes- Storage basics for lyophilized research peptidesGeneral laboratory guidance on temperature, light and moisture for keeping lyophilized research peptides as close as possible to their tested state.
- Organizing a research catalog for clarityResearch areas, permanent catalog codes and lot numbers — how the catalog helps you find the right material quickly and confirm exactly what it is.
