I've been researching on IGF-1 for a while now but I keep seeing different answers on injecting. Im about to order 2 kits & it says it comes with the mixing solution (BW) so why are people now using it? Doesnt it come in powder form like HGH? Im confused so any help is greatly appreciated. Also, I know im injecting my HGH sub-q so do I do the same for the IGF-1 or is it IM?
