Frequently asked questions
Are these products for human consumption?
No. All compounds on Ultra Peak Peptides are sold strictly for in-vitro laboratory research use. They are not drugs and are not intended for human or animal consumption.
How is purity verified?
Every batch is tested by reverse-phase HPLC and confirmed by LC-MS in our facility, then independently re-tested by an external accredited laboratory. The results are issued as a Certificate of Analysis with every shipment.
What forms do peptides ship in?
Sterile lyophilized powder under vacuum, sealed in amber glass vials. Reconstitute with bacteriostatic water before use.
