BPC-157 cycle length: what human studies ran

Not approved — research use onlyCPreclinical research
Short answer: there is no established BPC-157 cycle length or break. The human studies below ran for set periods under monitoring; none tested repeated courses.

Treatment and follow-up in human studies

  1. In the interstitial cystitis pilot, the injections were given during a single cystoscopy procedure, with no further treatment reported 10.
  2. The intravenous pilot study administered infusions on two consecutive days (day 1 and day 2), with follow-up blood work and vital signs on day 3 11.
  3. In the knee-pain chart review, follow-up varied because the study was retrospective; most patients had been injected 6 months to 1 year before the telephone survey 9.
  4. The registered rotator cuff study plans injections over 90 days after surgery (NCT07803250); the oral phase 1 record describes a single-dose part and a two-week repeat-dose part (NCT02637284); the completed gummy study ran 8 weeks (NCT07752381) 17,19,20.

What has not been tested

  • On-and-off schedules or breaks between courses.
  • Repeated courses and long-term exposure beyond the periods listed.
  • BPC-157 combined with other compounds, unless a study above says so.

Frequently asked questions

Is there an established BPC-157 cycle length?
No. Human studies administered BPC-157 for the periods listed on this page. Those are study durations; none tested an on-and-off schedule or a break.
What is the longest human study of BPC-157?
The durations are listed on this page with their sources; compare them directly rather than relying on a summary.
Do study durations tell me how long to use something?
No. A study duration is how long investigators administered a compound to selected participants under monitoring. It is not a recommended course, and a break between courses has not been tested for any compound on this site that is not approved.
