igf-1 should be reconsituted in AA which you can buy online for about $6. If reconsitituted in AA you can store it at room temp (for years), but personally i keep it in the fridge just to be safe.
People, myself included, are also backloading the syringe with BW to give the injection a little more volume and room for error.
human growth hormone has effects not associated with igf-1....such as bone growth and a more direct effect on fat loss off the top of my head. metabolism of hgh in the liver causes a release of igf-1
igf-1 is what increases protein synthesis (not as much as juice) and differentiation of myoblasts into myotubes (new muscle). it also has insulin like properties, so if you use slin you can use a lower dosage. We dont know exactly how igf-1 works yet...if youre a bodybuilder using igf-1 you are basically on the same level as a lab rat. i feel ok with this however and so does my new muscle tissue.
IGF-1 LR3 is the version that is used...regular igf-1 will spend about 20 mins in your system before it is bound by proteins. LR3 stays active for 20-30 hours
