I've been taking 500mcg under the skin in my knees preworkout on leg day and the the day after legs. I have chronic knee pain and swelling from bad injuries. BPC-157 allows me to train my legs much harder than I ever could normally. It reduces the swelling and pain on days that I take it. I tend to use it around my leg training. Everyday use would get a little pricey for me right now. This is one amazing healing peptide.
