In studies we see that BPC157 and most peptides in general have a higher % of absorption at the site of injection. This is why you here that people inject it IM into the muscle near the injury but not directly into the injury.
For me, with my own injuries and healing I did 250-500mcgs of BPC 1-2x a day. Of course 2x a day is better, but tbh its hard for many people to be able to pull this off w work and kids, etc.
Now BPC also is a miracle drug systemically. Alot of people don't realize this. Although you get a higher % absorption at the injection site, the majority of BPCs effects is coming systemically aka in the bloodstream. So this is why Oral consumption also works. Of course at a much lower rate. However oral consumption is great at healing the intestines, stomach and can treat issues like IBS, etc.
BPC is even effective in the eyes. I had a client who had horrible eye issues, blurred vision, etc. We started putting 250mcgs into her eye once a day and within a month we completely treated her issue and healed her 100%. You won't see or hear about this in any study or journal though.
Also we now have Nasal Spray versions. This too is effective but not as effective of course as INJ. This would of course be excellent for someone with sinus issues and inflammation but again is going to have Systemic effect. I don't know where else you can buy them, but we have them at Amino Asylum if no source here has them. Recon has the INJ version for anyone here interested. My code "WES15" works at both places
BPC 157 is a miracle drug imo.
