any pharms doing research with a slow release igf-1 yet?

[bronco944]

i know some pharmaceutical companies are looking into making igf-1 a prescription drug, so are any working on making it into a time release injection like nutropin depot? im sure they have the resources to make it happen. and if it were ever marketed as a drug for medical use, im sure this would be the route they would need to take, given igf-1's short half life.
