IGF expiring?

[Supra]

I bought this stuff back in 04, and its been mixed ever since, sitting in the fridge. You guys think its still good?

Nope.

that stuff is wayyyy past exp date

I do not agree that it is bad. It is probably weaker than normal. I'd still use it at a 50% higher dose. (provided its still steril) Here is Gropep's findings:

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.



Hope this helps you.

That helps a lot, I have had it stored in the fridge, the IGF is in AA solution.

well i can tell this stuff still has some life in it, i am injecting my test monkey with 20 mcg a day and hes getting really lean and hungry all the time

How long have you had your test monkey on it?
