TweetI ran it for a month for a very hurting bicep muscle. I mixed it with Bac Water. To get any effect the vial is empty in a matter of days. After 2 weeks tops I felt relief, after a month I was like whoa where has this sh!t been hiding. You can keep running it longer until you achieve the effect you want. BPC is very mild sides if any, and impact is huge. I was surprised.
