Looks like a pretty good deal on the LR3 IGF-1 ... why is it suspended in acetic acid while others are suspended (according to a sticky in the IGF1 section) in BA (i assume benzyl alcohol)?
So its the same procedure though, once the diluent is mixed with the powder? you draw out say .04 mL for 40mcg and then draw out enough bacteriostatic water to fill the syringe and inject into your lab animals, correct?
What can you tell me about the quality of manufacturing on this LR3 compared to other media grade LR3 from other 'trusted' companies.
First off, every peptide is very different. A lot of them have very similar peptide sequences but have far different properties. Human MGF is water soluble and can be diluted in bacteriostatic water, however, LR3 IGF-1 must be diluted in 100mM (or 0.6% w/v) acetic acid or the peptide will die. This is due to the fact that Acetic Acid at that molarity is the perfect pH to keep the peptide alive, anything out of that range and the stability of the peptide is greatly reduced.
I have seen posts talking about using benzyl alcohol, however, the only place people are getting this information is that stupid article by (damn I can't remember his name) in Muscular Development. Benzyl Alcohol cannot be used here. Gropep, who holds the patent on the peptide says 100mM AA must be used. They recommend a minimum of 1000mcg LR3 IGF-1/1mL of acetic acid. They say anything less than that concentration and the peptide will stick to the glass of the vial.
It is very easy to reconstitute this stuff. Simply get an insulin syringe, measure out 100 IU's of acetic acid, stick it in the vial, and slowly let it trickle down the side of the glass and onto the powder. Then just roll the vial around in your hand and let it dilute. There is no need to add bacteriostatic water to the syrgine after drawing the IGF-1 solution out, unless you are a wimp and can't take the minor sting of the acetic acid.
Thanks for the kind words
