I know this post is several months old, but I've been researching bpc 157 for this exact same reason. Turns out there were 2 different forms of the peptide used in the actually lab studies. There was/is the acetate version which was used for subQ & IM injections in rats an mice. This version is not very stable which is why it needs to be handled carefully & stored below 40*F. Acetate is what's commonly available on the internet. Then there was the orally stable version which was obviously for oral administration, usually by adding it to the animals water. This version can be stored at room temp, & is much less susceptible to damage from shaking. It was created & patented by a company called Daigen (sp?) somewhere over in Europe. They are the only supplier of orally stable BPC 157. -On a side note, it appears there are many anecdotal posts/reports of people taking the less stable acetate form orally & still experiencing great results for just about everything. Likewise there are a lot of people that say oral administration was useless & a waste. This is the problem w/anecdotal reports... it's nearly impossible to determine placebo from actual effect. My Conclusion: BPC 157 is cheap enough to try both methods at the same time. I bought 2/ 5mg vials & just started my treatment yesterday. I'm doing 250mcg sublingually first thing in the morning, & 250mcg IM injection alternating in my right & left delts (I also have clicking/rotator cuff issues in both shoulders) every night before bed. There are many reports of BPC also helping with sleep. (Placebo? I'll find out) If my calculations are correct I should have enough BPC for 21 days. If anyone's interested I'd be happy to do a follow up post at the end of Feb.
