    **New Studies showing increased Stability of IGF-I

    Stability Data for LongTMR3IGF-I (Liquid Formulations)

    The stability of a liquid solution of LongTMR3IGF-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 LongTMR3IGF-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


    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


    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


    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


    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


     Conclusions

    o There is no significant difference in the potency of LongTMR3IGF-I associated with the storage of the liquid formulation when stored at this range of temperatures.
    o There is no evidence for loss of biological activity at any of the tested temperatures when stored as a liquid product.



    ------------------------------------------------------------------------
    I dug up this data to help educate people on LR3 IGF-I. As with many products like this false data almost always surrounds it as truth. The above information was gathered by gropep during experiments which stretched several years.

    As you can see IGF can be quite stable for even a year at room temp

    Wow that's good to know. I actually have a little left over that's been @ room temperature. Maybe I'll incorporate it in my next cycle!

    I keep mine in the freezer, but it looks like it doesn't matter, here the conversion of Celsius to Fahrenheit.

    -20C = -4F
    4C = 39.2F
    22C = 71.6F
    37C = 98.6F

    So it's good for 1 year at body temperature

    So if you're having trouble putting it in the fridge due to roommates or something you easily could store it in a cool dark place although already reconstituted? I don't know what to think of that but apparently it seems like.

    Personally I would still recommend keeping it in the fridge and I will continue to ship in insulated containers with cold packs. But this info is definately nice for peace of mind
