Studies have shown that in this state the peptide can withstand temperatures of up to 37degrees for a month at a time without losing any potency or effectiveness. This also means that the peptides needs to be reconstituted back into a liquid before use!  This is easily achieveved with the use of antibacterial sterile water.
