Shelf life of peptides

The shelf life of peptides is the period during which these biosynthetic products, provided that the storage conditions stated in the instruction are met, preserve their pharmacological properties.

The shelf-life of peptides is determined by the date placed on the vial and the outer packaging. It is this number that guarantees the manufacturer that the drug will maintain chemical stability and exert the necessary impact without posing a potential hazard to human health. However, the date indicated on the peptide package may be considered relevant only until the lyophilized powder contained in the vial was mixed with the solvent and did not gain access to air.

The shelf life of peptides in dry form is 1-2 years (depending on the variety of the drug). These substances, which have a very fragile structure, are afraid of high air temperature, direct sunlight, shaking and shaking.

The group of the most "fragile" peptides, rapidly losing their pharmacological properties under various fluctuations, includes:

• Peg MGF;
• Gonadorelin;
• GRF 1-29;
• IGF-1LR3;
• MGF;
• HGH Frag (176-191).

When buying these products, strongly demand that the seller treat your parcel with due attention by placing a cold storage battery inside it, keeping the temperature at the right temperature, carefully packing it, and gluing it with adhesive tape. It is preferable to store "fragile" peptide products in the refrigerator, since at room temperature their lifespan does not exceed 10 days.

To ensure that the shelf life of the peptides corresponds to the declared manufacturer, the preparations should be stored at a temperature of 3-8. If the drugs are stored in the freezer, they should not be re-frozen. Dilute lyophilized powder strictly according to need. In diluted form, it can also be stored in the refrigerator, but no more than 6-10 days (the specific storage date should be indicated in the instructions). Mixed ampoules are strictly forbidden to be frozen. Some peptide preparations can be stored at room temperature, unopened for about 2 months, in the printed - no more than 48 hours.
