Today I got hit with a bunch of ads on Facebook for the above. I see that some of the ads are targeted for irritable bowel syndrome (IBS). My first impression is what is it? Has it been demonstrated to help anything (besides the pocket book of promoters)? What is the probable monthly cost of an effective dosage? This post attempts to answer these questions. Similar posts from the back:
The aim of this paper is therefore to critically review the current literature surrounding the use of BPC 157, as a feasible therapy for healing and functional restoration of soft tissue damage, with a focus on tendon, ligament and skeletal muscle healing. Currently, all studies investigating BPC 157 have demonstrated consistently positive and prompt healing effects for various injury types, both traumatic and systemic and for a plethora of soft tissues. However, to date, the majority of studies have been performed on small rodent models and the efficacy of BPC 157 is yet to be confirmed in humans.Gastric pentadecapeptide body protection compound BPC 157 and its role in accelerating musculoskeletal soft tissue healing 
The first question is simple, should be expect it to be confirmed in humans? The longer it has been since discovery, the higher the probability. IMHO 5-7 years is a reasonable expectation. Turning to PubMed, we see it has been written about for thirty years.
What is it?
Pentadecapeptide BPC 157, composed of 15 amino acids, is a partial sequence of body protection compound (BPC) that is discovered in and isolated from human gastric juice. Experimentally it has been demonstrated to accelerate the healing of many different wounds, including transected rat Achilles tendon.The promoting effect of pentadecapeptide BPC 157 on tendon healing involves tendon outgrowth, cell survival, and cell migration 
The version being sold is patented, older versions do not survive stomach acid etc. The patent gives the sequence of these amino acids is given in the patent, “pentadecapeptide (abbr. BPC-157 or bepecin) having an amino acid sequence: Gly Glu Pro Pro Pro Gly Lys Pro Ala Asp Asp Ala Gly Leu Val “
The FDA has issued warnings about it. From unsafe manufacturing , as well as other agencies
While the peptide BPC-157 is not presently included on the World Anti-Doping Agency (WADA) Prohibited List, it is important for athletes to be aware that this substance is not approved for human clinical use by any global regulatory authority, it may lead to negative health effects, and it could be added to the Prohibited List at any time based on new research.

Who is selling it?
There is a clinical study from 2015 that I found PCO-02 – Safety and Pharmacokinetics Trial The high dosage was 8-24 mg/day. Thus the above bottle is enough for 4 days, so about $450/month. There has been no update of this trial for 7 years. Usually, no update means no positive results (99% of the time)….
There is no trustworthy evidence that it helps, it has a high cost (when purchased from the promoters) and lack FDA approval (it is being sold as an unregulated supplement). The price being asked is CRAZY! Some sources are selling it in bulk for as low as $3/kilogram! So BEWARE and save your money!
