How to store MGF

Practical storage protocol for MGF: temperature, light, reconstitution timing, and shelf life in a research setting.

Lyophilised (freeze-dried) storage

Unreconstituted MGF, like most research peptides, is stable when stored in its original sealed vial at -20°C for long-term storage. For short-term use (under 3 months), refrigeration at 2-8°C is acceptable. The vial must be protected from direct light and moisture.

Peptify dispatches MGF in temperature-tolerant packaging from the UK, usually arriving within 24-48 hours of dispatch.

After reconstitution

Once MGF is reconstituted with bacteriostatic water (BAC water, 0.9% benzyl alcohol), the solution should be stored at 2-8°C (refrigerated) and used within 28 days. Bacteriostatic water's preservative system inhibits microbial growth for roughly four weeks after first puncture — significantly longer than sterile water, which must be used immediately.

Avoid freeze-thaw cycles. Never leave the vial at room temperature for extended periods, and keep it in its original rubber-stoppered vial to minimise contamination risk.

Shelf life and quality verification

Peptify publishes a batch-specific expiry date on every MGF COA, alongside HPLC chromatogram data and mass spectrometry confirmation. The full Certificate of Analysis for your specific batch is downloadable from the product page.

Frequently asked questions

What is MGF?

MGF (Mechano Growth Factor) is produced in response to mechanical stimulus or exercise stress. It is studied in the satellite-cell activation and skeletal-myocyte pathway literature.

How does MGF relate to IGF-1?

MGF is a splice variant of IGF-1, sharing structural elements but expressed in response to different stimuli. Research has examined whether the two variants activate overlapping or distinct downstream pathways.

What purity does Peptify MGF meet?

Peptify MGF is 99%+ HPLC-verified with a batch-specific Certificate of Analysis from Janoshik Analytical, published on the product page and downloadable directly.
