Peptides Studied for Recovery
Recovery is one of the most common reasons people explore peptides. BPC-157, TB-500, and GHK-Cu have all been studied in animal models for tissue repair, wound healing, and inflammation reduction.
The animal evidence for BPC-157 is extensive — over 100 published studies covering tendons, ligaments, muscle, gut lining, and bone. TB-500 draws on the wound-healing properties of its parent protein, Thymosin Beta-4. GHK-Cu is a naturally occurring copper peptide with decades of research in skin and tissue remodeling.
But human clinical data remains extremely limited for all three. BPC-157 has only three small human studies. TB-500 has zero human trials for the fragment itself. GHK-Cu's strongest human evidence is for topical skin applications, not injectable recovery use. Here's what the research actually shows for each.
BPC-157
Body Protection Compound-157
A synthetic pentadecapeptide studied for tissue repair, gut healing, and recovery. Extensive animal data, very limited human evidence.
TB-500
Thymosin Beta-4 Fragment (17-23)
A synthetic heptapeptide fragment of Thymosin Beta-4. Studied for wound healing and tissue repair, primarily in animal models and equine medicine. Zero human trials for the fragment itself.
GHK-Cu
Glycyl-L-Histidyl-L-Lysine Copper(II) Complex
A naturally occurring copper tripeptide found in human plasma. Moderate evidence for topical skin rejuvenation; limited evidence for injectable forms.
