IGF1 LR3 is an extremely fragile peptide, and should be handled with care. It can easily be destroyed by improper storage or handling. It is usually supplied in either 100mcg or 1mg peptide vials, containing freeze dried powder that needs to be reconstituted. When reconstituted with % acetic acid solution it has a maximum shelf life of 2 years. If using bacteriostatic water it has a 30 day shelf life, or 24-48 hours with % NaCl sterile water. When reconstituting add the water very slow to the vial and do not shake it. The solution should be stored in the fridge at 2-4°C.
