BPC-157
AnimalBody Protection Compound 157 · PL 14736
A synthetic peptide fragment derived from a gastric protein, studied almost entirely in rodents for soft-tissue and gut healing.
TB-500
AnimalThymosin Beta-4 (synthetic) · Tβ4
A synthetic version of thymosin β-4, a naturally occurring actin-regulating peptide studied for tissue repair — mostly in animals, with a few early human trials of the parent molecule.
GHK-Cu
Human obs.Copper Tripeptide-1 · Copper Peptide
A naturally occurring copper-binding tripeptide with the most direct human data in the Recovery cluster — but almost all of it is topical, cosmetic, and small-scale.
KPV
AnimalLysine-Proline-Valine · α-MSH(11–13)
A tiny three–amino-acid tail of the α-MSH hormone studied for anti-inflammatory effects, especially in the gut and skin — preclinical so far.
TB-500 Fragment
In vitroTβ4 fragment · Actin-binding domain peptide
The short, actin-binding fragment that most "TB-500" products actually contain — frequently confused with the full thymosin β-4 molecule used in clinical research.
Pentadeca Arginate
TheoryPDA · BPC-157 Arginate
A newer, chemically modified relative of BPC-157 marketed as more stable — but with virtually no published peer-reviewed studies of its own yet.
