I remember crushing aspirin and mixing it in DMSO to rub on injuries.She helped me, I really distrust standard medical treatment. I'm well trained enough to know what I need and I know certain kinds of guerrilla medicine to help me take care of myself. I've used peptides and pentosan sulfate with great success. Both are available over-the-counter and are easy to use. Essentially you use a subcutaneous injection close to the injury site with either one. pentosan is pretty systemic so if you go close to your injury site or just use it in a general sense. I recommend approximately 1 mL weekly for people who want to be prophylactic about any type of arthritis.
It's been shown to reduce inflammation and potentially reverse cartilage damage. And it's not hard at all under river and kidneys, unlike nsaids.
For the BPC 157 I'd break it up and do it daily for a few weeks. Taking off a Saturday and Sunday help stretch a little bit farther. It's approximately $70 for a five or 10 mg bottle. You have to reconstitute it with sterilize water and then you would use an insulin needle to go subcutaneously near your injury site.
Boy have times changed.
