Osteoarthritis in shoulders bilaterally and 2 herniated discs in my neck.
Not something that BPC-157 can fix or help much.
Research showed not very promising results about BPC for osteoarthritis, probably because cartilage is avascular therefore BPC is unable to reach it and anyway growth factors are unable to reach it, not in enough amounts anyway.
Perhaps it may contribute to help but not alone, maybe in conjunction with other means.
Herniated discs can't be fixed by BPC neither since it is a mechanical and/or cartilage issue.
I recommend you ozone or prolozone therapy for those as a more immediate and likely effective solution.
Than my question remains valid, I ve searched and not found anything on pubmed that shows that different administration method for BPC-157 are eqivalent
I don't want to sound unfriendly but under BPC157 there are 6 pages for a total of 109 results in Pubmed (which I have all investigated, doing my homework, I guess), already in the first page you'll find this one, for example:
https://www.ncbi.nlm...pubmed/26875638
BPC 157 was provided daily, perorally, in drinking water (10µg/kg, 12ml/rat/day) until sacrifice or, alternatively, 10µg/kg or 10ng/kg intraperitoneally....BPC 157 given perorally or intraperitoneally and in µg- and ng-regimens rapidly improved the whole presentation...
The same recurs in all studies where both methods of administration are applied (which are not all but many), in some studies intramuscular and topical are included too, always leading to no difference in outcomes.
For cornea lesions eyedrops have been investigated too, leading to positive results, of course.
Route of administration doesn't seem to effect outcomes, not when performed appropriately at least.
If more evidence is required please don't ask me to provide it but do your own homework, I already did mine.
Now, with this BPC thing out of the way lets go back on topic which is MK-677.
Eventually lets open a new dedicated tread to BPC, which would be interesting indeed.
By the way I get my BPC from whom discovered it and provides it to almost all researchers you'll find in Pubmed, it is reasonably priced, it is available in a patented version which doesn't requires refrigeration too and the guys there are extremely fast in providing competent support, I am not involved in the business in any way but whom is interested may PM me to get the source address (Europe).
