Administration- I believe in IM injections over sub q, but either seems to be effective. I like IM better because IM using a slin pin is probably the least painful thing one could imagine, even at two times per day. Also, sub Q shots that contain BA, even diluted BA, can leave little nodules that you may not want to feel on your stomach.
Mixing- Most IGF comes suspended in BA. Hopefully it is @ 500mcg/ml or even 333mcg/ml (that would be at 2ml/mg and 3ml/mg respectively) Draw out your desired amount and back load a slin pin. Add enough bacteriostatic Water to fill the U100 syringe completely.
Some inject immediately before training, while others choose to do 2 shots spread throughout the day... THEY BOTH WORK WELL. Try both; see which method makes your muscles pop out of your skin.
I just got this info from knowledgable member of this forum hope it helps
