Research-material prices should be compared using the same molecule, chemical form, quantity and documentation level. Two vials with similar names are not automatically equivalent.
What the price may include
Cost may reflect synthesis or manufacture, independent analysis, packaging, transport monitoring, documentation, taxes and losses from rejected batches.
The cost of an invalid result
A cheap but uncharacterised material can consume laboratory time, reagents and capacity. The real cost includes the risk of repeating the experiment.
How to compare
Check declared quantity, identity, form, batch, method, laboratory, storage conditions and commercial status. PeptidaLab displays recommended prices but blocks ordering until checks are complete.
Conclusion
Price is a criterion, not evidence. A sound comparison puts documentation and protocol suitability ahead of promotional percentages.
