    "Storage- the most popular (and most effective) way to store, transport, preserve IGF is by suspending it in sterile BA in a sterile vial.
    This will keep your IGF 99% potent for many months at a time in just about ANY indoor storage, I.E.-closet, drawer, etc."

    I read everywhere that AA is far better then the use of BA. But these are just some exsamples of tons of stuff on the net.

    So I figure I would ask people with experience. Any info will help.
    Reconstitute your LR3 multi-use vial with diluted sterile acetic acid should you want to preserve potency for extended length & wish to buffer injects with either bact water/nacl. Should you not follow the hype, simply reconstitute with bacteriostatic sodium chloride, use within a month & be done with the fear(s) the long chain amino acid will hide in pores and/or degrade.

    Thanks for the info. What about having to keep it in the fridge? I read a study graph that has been around for awhile

    Storage of LR3 IGF-1
    *Study conducted by Gropep

    The stability of a liquid solution of LR3IGF-I was monitored for a period of two years at storage conditions of -20 C, +4 C, +22 C, and +37 C. The final concentration of LR3IGF-I was in acetic acid. At various time points, samples were taken and compared to a lyophilized control (stored at 4 C). Listed below are the stability results for each respective storage condition.


    Storage Condition: -20 C (-4 F)
    Biological Potency No Change up to 2 years
    Immunological Activity No Change up to 2 years
    Mobility of Protein No Change up to 2 years
    Elution Profile by reversed phased HPLC No Change up to 2 years

    Storage Condition: +4 C (39.2 F)
    Biological Potency No Change up to 2 years
    Immunological Activity No Change up to 2 years
    Mobility of Protein No Change up to 2 years
    Elution Profile by reversed phased HPLC No Change up to 2 years

    Storage Condition: +22 C (71.6 F)
    Biological Potency No Change up to 2 years
    Immunological Activity No Change up to 2 years
    Mobility of Protein No Change up to 2 years
    Elution Profile by reversed phased HPLC No Change up to 2 years

    Storage Condition: +37 C (98.6 F)
    Biological Potency No Change up to 1 year
    Immunological Activity No Change up to 1 year
    Mobility of Protein No Change up to 1 year
    Elution Profile by reversed phased HPLC No Change up to 1 year

    In conclusion, there is no significant difference in the potency of LR3IGF-I associated with the storage of the liquid formulation when stored at this range of temperatures. There is no evidence for loss of biological activity at any of the tested temperatures when stored as a liquid product. As you can see IGF can be quite stable for even a year at room temperature, but if you want to keep it around for a while then stick it into the fridge. So in my opinion the best way to store LR3 that is suspended in BA (benzoic acid) is in the freezer. The BA won’t allow it to freeze. And if you have it suspended in AA (acetic acid), store it in the fridge.


    Thoughts??

    Chill in the fridge, yes sir
