Tesamorelin / Ipamorelin 10mg

Storage Instructions

It is a truth universally acknowledged that a peptide in possession of superior quality must be in want of proper storage. No researcher of discernment can have failed to observe that the maintenance of peptide stability depends upon the faithful adherence to storage protocols of a most particular nature. The guidelines which follow have been composed with scrupulous attention to the preservation of this lyophilized formulation.

Lyophilized Peptide Storage

One must exercise the utmost care in storing unopened vials, which ought to be kept at temperatures of -20°C or, if circumstances permit, at the more advantageous temperature of -80°C. These vials must remain within sealed containers, affording them protection from the unwelcome intrusion of both light and moisture. Before one ventures to open any vial, it is of paramount importance to allow the vessel a period of equilibration to room temperature, thereby preventing that most undesirable phenomenon known as moisture condensation.

Lyophilized peptides stored at -20°C maintain their stability for a period of 2-4 years; storage at -80°C, however, provides preservation of an even more optimal character. One would be well advised to employ airtight glass vials fitted with PTFE-lined caps. After removing such quantities as research demands require, the prudent course is to purge the containers with dry nitrogen or argon before resealing. Peptides containing cysteine, methionine, or tryptophan residues demand particular vigilance with regard to oxidation prevention, being especially susceptible to such degradation.

Reconstituted Peptide Storage

Following reconstitution, one must store the resulting solutions under refrigeration at 2-8°C for durations not exceeding 30 days. Should one require storage of a more extended nature, it becomes necessary to divide the reconstituted peptide into aliquots intended for single use only, thereafter storing these portions at -20°C or -80°C.

The employment of sterile buffers at pH 5-6 proves most conducive to achieving optimal stability. One must strenuously avoid repeated freeze-thaw cycles, which accelerate degradation in a manner most prejudicial to research objectives. Reconstituted solutions demonstrate considerably diminished stability and consequently require handling protocols of a more stringent character.

Container Requirements

The selection of appropriate containers deserves no less attention than any other aspect of peptide storage. One must utilize vessels that are clean, chemically resistant, and structurally sound. Glass vials offer protection of a superior nature; polypropylene containers, however, provide acceptable alternatives. One must ensure proper sealing and maintain a respectful distance from frost-free freezers, which undergo temperature fluctuations most prejudicial to peptide preservation.
