////// Ask AURUM
Straight answers.
Usually, yes. A kit spreads packaging, fulfillment, and handling across ten vials instead of one, which commonly cuts the cost per vial by around half compared with buying single vials. Run your own numbers in the calculator.
Most of a single vial's price isn't the peptide. It's per-unit packaging, fulfillment, middlemen, and in clinics, service markup that can reach ten times the material cost.
Look for batch-specific, third-party certificates of analysis that report purity by HPLC and identity by mass spectrometry, match the batch number on your product, and come from a lab you can contact independently.
It's a peptide that has been freeze-dried into a stable powder or "cake." Removing the water helps it stay stable during storage and shipping until it's reconstituted for research use.
