I posted a question about injecting IGF in the quads. My question this time is say you use IGF-1Lr3 ok, you train bi's and tri's on the same day after you work out do you need to inject both the bi's and tris' or just one of each on each arm? I know the Lr3 will float around till it binds to receptors, if it was the MGF or regular IGF then I would do both bi's and tri's that my question. Say 80mcg PWO would that be 20mcg in the bi and tri area on each arm to equal 80mcg altogether?
