Storing Peptides

Mixed Peptides

Storage: Reconstituted (mixed) vials must be stored in the refrigerator (2 to 8 degrees celcius).
Expiry: Use within 8 weeks (2 months) of mixing.

It is NOT recommended to pre-load syringes and freeze them. When the peptide freezes there is a risk that it may come out of solution into particles. When it is thawed out again it may not return into solution, meaning particles will be injected which can cause irritation or damage at the injection site.

Note: PRE mixed peptide vials should not be shaken under any circumstances. None of our peptides come pre mixed and ALL packages include free solvent.

Unmixed Peptides

Storage: In powder (lyophilized) form vials should be stored frozen (0 to -20 degrees celcius).
Expiry: Will remain stable up to 48 months (4 years) in the freezer.

Unmixed vials can be stored in the freezer for a period of up to 48 months (4 years); however, if you are going to use the vials within 1 months then we recommend simply storing them in the refrigerator as repeated freeze-thaw cycles can cause damage to the peptide.

Storage Safety

Both mixed and unmixed vials should be stored inside sealed plastic satchels or containers and kept away from food in the refrigerator or freezer.
