What "Reconstitution" Means
Many peptides ship as a dry, lyophilized powder to preserve stability. Reconstitution means adding a sterile diluent to dissolve the powder into a solution for controlled research handling and measurement.
Typical Supplies
Sterile diluent as specified by the product documentation (commonly bacteriostatic water in many lab contexts)
Sterile syringes/needles appropriate for transfer (not for administration)
Note: "Extended shelf life" depends on compound stability, diluent type, storage temperature, and handling practices.
Troubleshooting
My solution looks cloudy — what now?
Cloudiness can indicate incomplete dissolution, temperature effects, or contamination. Gently swirl (don't shake) and let it rest chilled. If cloudiness persists, do not use for research until you verify handling conditions and product guidance.
The powder won't dissolve easily.
Add diluent slowly, avoid foaming, and allow time. Some peptides dissolve better with gentle rolling and patience. Avoid heat and vigorous shaking.
Can I re-freeze a reconstituted vial?
Many labs avoid repeated freeze/thaw cycles because they can degrade sensitive compounds. If long-term storage is required, consider aliquoting (splitting) in sterile conditions—only if your product documentation supports it.
What diluent should I use?
Use the diluent specified by your product documentation. When not specified, many research environments use sterile options such as bacteriostatic water. The correct choice can vary by peptide, intended research method, and storage plan.
FAQ
Why are peptides shipped lyophilized?
Freeze-drying improves stability during shipping and storage by removing water, which helps reduce degradation for many compounds.
Do you provide lab testing?
Many products are supported by third-party testing and batch documentation when available. Check the product page for lab report details.
