Vials vs Prepared Research Pens
VQ Health supplies many compounds in two formats. The choice is about laboratory workflow, not potency.
Lyophilised vials
Freeze-dried compound in a crimp-sealed vial. Advantages for research: longest shelf stability at -20C, flexible preparation volumes in the lab, straightforward analytical sampling. The laboratory controls preparation entirely.
Prepared research pens
Pre-filled, sealed pen-format devices containing prepared research material at a defined quantity. Advantages: consistent preparation, no reconstitution step, convenient aliquot-style handling in volumetric laboratory work.
What stays the same
Both formats carry batch numbers, both are covered by the same COA library, and both are supplied strictly for in-vitro laboratory research.
Storage difference
Lyophilised vials tolerate freezer storage well; prepared liquid formats are typically kept refrigerated (2-8C) and used within the documented stability window. See each product's storage section.
