No prescription is needed for any of the products we offer online. However, for specialized products like peptides, we recommend consulting with your healthcare provider or a Kalista medical professional for guidance.

Peptiva Lab are commited to transparency, quality, and compliance with international regulatory standards. Our products are labeled “Research Purpose Only” because they are intended strictly for use in scientific, laboratory, or investigational research by qualified professionals.

Peptides are supplied in lyophilized (freeze-dried) powder form to ensure maximum stability, purity, and extended shelf life. This format protects the peptide from degradation during transit and storage, making it the preferred standard in scientific research.

Before use, the powder is typically reconstituted with a sterile solvent such as Bacteriostatic Water (BAC Water)—which is also available for purchase on our website. This allows researchers to prepare the solution according to their specific study requirements while maintaining the peptide's integrity.

Unreconstituted (powdered) peptides should be stored in a cool, dry place—ideally in the refrigerator (2°C–8°C) to preserve potency. For long-term storage, freezing at -20°C is recommended.

Once reconstituted with a solvent like BAC Water, peptides should be stored in the refrigerator and used within a short period, depending on the research protocol. Avoid repeated freeze-thaw cycles, as this may degrade the compound.

Note: Kalista Wellness does not provide guidance on dosing, handling, or application. Products are intended for research use only.
