We don't offer returns due to the delicate nature of our products. You can cancel your order, but you must do so before it ships. Once it's shipped, cancellations are not possible. If you need immediate assistance with questions, want to cancel, or if your order arrives with issues like missing, incorrect, or damaged items, please reach out to us at info@nexusbiolife.com.
Certificates of Analysis are provided for all products we offer. This information can be accessed by navigating to the product page of the specific peptide you intend to purchase or by viewing our Lab Results page.
Proper storage of reconstituted peptides (those dissolved from lyophilized powder into a solution, typically using sterile water, bacteriostatic water, or another suitable solvent) is crucial to maintain their stability, potency, and integrity. Peptides in solution are more prone to degradation than in lyophilized form due to factors like hydrolysis, oxidation, and microbial contamination. General best practices are derived from scientific and pharmaceutical guidelines, though specific conditions can vary by peptide type, sequence, and intended use—always check the manufacturer's instructions if available.
Key Storage Guidelines
Immediate Handling After Reconstitution: Use the peptide solution as soon as possible after dissolving. If not using immediately, divide into single-use aliquots to minimize exposure and degradation. Avoid leaving the solution at room temperature for extended periods (limit to minutes or hours at most).
Temperature:
Avoid Freeze-Thaw Cycles: Repeated freezing and thawing can cause peptide aggregation or breakdown. Aliquot the solution into portions that match your usage needs, so you only thaw what you'll use at once. If thawing is necessary, do so slowly in the refrigerator or at room temperature—never use heat or microwaves.
Light and Environment Protection: Store in opaque or amber vials to shield from light, as UV exposure can accelerate degradation. Keep in a dry, dark place away from humidity. Use desiccators if available for extra protection against moisture.
Solvent and pH Considerations: The choice of solvent (e.g., sterile water for acidic peptides, basic buffers for others) affects stability. Ensure the pH is appropriate for the peptide to prevent denaturation. Add preservatives like benzyl alcohol if using bacteriostatic water for multi-dose vials.
General Tips:
Following these practices can extend the usability of reconstituted peptides significantly, but degradation is inevitable over time in solution. If in doubt, err on the side of caution and prepare fresh reconstitutions.
If it isn't made in the USA, you know nothing about the manufacturing process used to produce peptides. Our research peptides are of the highest quality and produced in the United States. Nexus Bio Life ensures all its research peptides are manufactured domestically within the United States. This American production allows for rigorous quality control, with manufacturing teams meticulously working to eliminate contaminants and impurities. We prioritize following the most current Good Manufacturing Practices, implementing thorough sanitization at every step of production. Additionally, the use of cutting-edge peptide synthesis methods in American facilities, including advanced solid-phase techniques and sophisticated purification processes, contributes to the exceptional quality of our peptides.
