Evidence Comparison
Compare BPC-157, TB-500, GHK-Cu side by side using the same BACToBasics evidence dataset that powers the interactive comparison tool. The table below focuses on mechanism, regulatory status, human evidence, safety context, anti-doping context, and primary sources.
Recovery & Healing
Not FDA-approved
Very limited human evidence
Synthetic 15-amino-acid peptide with proposed repair-related signaling effects derived largely from preclinical models.
BPC-157 has a large online reputation but a very small direct human evidence base relative to the strength of the claims made for it.
Open BPC-157 guide →Recovery & Healing
Not FDA-approved
No meaningful direct human therapeutic evidence
Synthetic Ac-LKKTETQ fragment associated with the actin-binding region of thymosin beta-4.
TB-500 should not inherit the evidence base of full-length thymosin beta-4; direct human evidence for the fragment is exceptionally thin.
Open TB-500 guide →Skin & Hair
Not FDA-approved
Very limited human evidence
Naturally occurring copper-binding tripeptide associated with extracellular-matrix, collagen, and wound-repair signaling.
GHK-Cu is a route-dependent evidence story: topical cosmetic evidence exists, but it should not be used to imply injectable efficacy or safety.

Regulatory status and evidence level are separate ideas. A compound can have meaningful human research and still remain investigational, while an FDA-approved product can have approval only for specific indications and formulations.
BACToBasics also separates direct human intervention evidence from animal, cell, endogenous-biology, or related-molecule evidence so weaker evidence does not inherit the certainty of stronger research.
This page is generated from the same structured evidence records as the main interactive compare tool. Updating a compound's regulatory status, evidence summary, safety context, or source list updates both experiences rather than maintaining separate copies.
