Handled correctly, stability holds
All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.
Store vials in a cool, dry place away from heat and direct sunlight.
For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.
Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.
Frequently Asked Questions
PRODUCT & PURITY
This product is offered for laboratory and research use only. It is not intended for human consumption, medical use, therapeutic use, or veterinary use.
Yes, all of our products are sterile and sealed with a sterility plug and safety cap.
Our products undergo quality control internally at our lab and then 3rd party tested at Bioviridian (at their Texas facility) prior to shipment. All of our COA's are then posted on our site immediately upon receipt.
99% or higher. Period. The expected purity is listed on the individual product page or Certificate of Analysis, when available.
No. We are a manufacturing company and because these products are sold for research purposes only, we do not provide dosing, administration, or medical-use guidance.
Unless specifically stated otherwise, these products are not approved by the U.S. Food and Drug Administration for therapeutic or diagnostic use.
STORAGE & STABILITY
As a lyophilized powder, peptides are stable. Delays in shipments up to 7 days will have zero to minimal impact on efficacy of peptides. Most precautionary efforts must be made to maintain temperature consistency once reconstituted.
Store the product according to the storage recommendations provided on the label or accompanying documentation in your shipment. Proper storage helps maintain product integrity during its shelf life. Most peptides have an expiration date of 2 years if kept unreconstituted (lyophilized powder).
SHIPPING
Shipping times vary based on your location and the shipping method selected at checkout. We offer shipping options between 1 and 5 days.
No.
Once your order is processed, you will receive a shipping confirmation email with tracking information.
