BPC-157
The one the EDS community asks about most. Animal data on tendon and gut healing is genuinely interesting; human data barely exists.
Not approved anywhere
| What it is | A synthetic 15-amino-acid chain based on a sequence found in human gastric juice. It does not occur in the body in this form. |
|---|---|
| How it is thought to work | In animals it appears to promote new blood vessel growth, up-regulate growth hormone receptors in tendon cells, and protect gut lining. The pathways most often cited are VEGFR2 signalling and nitric oxide. |
| What the evidence actually shows | Dozens of rodent studies report faster tendon, ligament, muscle and gut healing. That body of work comes overwhelmingly from one research group, which is a real limitation. There are no published, adequately powered human trials for tendon or joint healing. |
| Regulatory status | Not approved as a drug in the US. The FDA has not placed it on the 503A list of bulk substances that compounding pharmacies may use, and in 2023 flagged it among peptides raising safety concerns for compounding. Sold in the US only as a research chemical. |
| Dosing | No established human dose. No trial has determined a safe or effective dose in people, so any number circulating online is extrapolated from rodent studies rather than measured in humans. |

Risks and cautions
- Long-term safety in humans is unstudied.
- Its pro-angiogenic effect is the mechanism behind the healing claims, and it is also the reason for a theoretical concern about feeding existing tumours. No human data either way.
- Prohibited in sport by WADA.
Why this matters specifically with EDS
This is the compound most often raised in hypermobility groups because tendon and ligament laxity is the core problem. Worth being clear-eyed: nothing in the research was done in people with a collagen disorder, and BPC-157 does not change the underlying collagen defect.
