# The Signed Source Record

> References — Recovery & Tissue Repair Research Peptides — Peptides For Puppies — The 17-source index for Peptides For Puppies and its Recovery & Tissue Repair research peptides briefings.

**RECOVERY FILE / REFERENCES**

Seventeen sources across human, cell, and animal-model research; none is a puppy clinical study or canine efficacy trial.

## References

The index below is the complete signed source set used for the BPC-157, GHK-Cu, and TB-500 briefings. Each citation appears once and is referenced by number throughout the site. Study type and species are kept explicit in the prose. One source includes adult-dog pharmacokinetic work, but the set contains no canine clinical efficacy trial and no puppy or juvenile-animal safety or efficacy study. The list supports literature review only; it does not establish veterinary use.
