See spotinjections.com, great info there. Many here have used b12 along with their IGF-1. 1/2 cc is probably fine, the dosage of b12 is up to you. Whatever the body can't use, it gets rid of it.
Thanks bros. My question about the 1/2cc of B12 was to make sure that was enough volume to dilute the BA in the IGF. I know many have backfilled the pin with 1cc of BW. A bro emailed me a picture of his pec where a straight shot of IGF had deterioated some of the muscle under the skin. I'm shooting IM and wanted to make sure I was not doing any deep tissue damage.
