- Category: Growth & Performance
What the research says
- IGF-1 LR3 is studied as a modified growth-factor analog for its role in muscle growth and lean mass.
- Lyophilized research peptides of this class are valued for stability and consistent reconstitution.
- Independent third-party testing confirms batch-level purity before release.
Laboratory research only. Not for human or veterinary use.
Storage Guidelines
To maintain product integrity, proper storage conditions are recommended throughout handling and use.
Unreconstituted (lyophilized) peptide
- Store at 2–8°C (in the fridge) for short-term use
- For extended storage, keep at -20°C or below (in the freezer)
- Protect from direct light and moisture
Reconstituted solution
- Store at 2–8°C and use within a limited timeframe
- For longer-term storage, aliquoting and freezing at -20°C is recommended
- Avoid repeated freeze-thaw cycles, as this may affect peptide stability
