GLP-1 receptor agonist

Semaglutide

A 31-residue analog of human GLP-1 (~94% sequence homology) with a C18 fatty-diacid chain attached via a linker — the modification drives reversible albumin binding and extended plasma half-life. The GLP-1 receptor agonist researchers reference by this name.

GIP + GLP-1 dual agonist

Tirzepatide

A 39-residue synthetic linear peptide engineered as a dual receptor agonist at both the GIP receptor and the GLP-1 receptor. Developed by Eli Lilly; the dual incretin-receptor agonist researchers reference by this name.

GIP + GLP-1 + glucagon triple agonist

Retatrutide

A synthetic 39-amino-acid peptide (also known as LY3437943) that binds three receptors: GIP, GLP-1, and glucagon. Investigational Eli Lilly compound; not FDA-approved as of writing.

Gastric pentadecapeptide

BPC-157

A synthetic 15-amino-acid peptide fragment corresponding to a sequence in Body Protection Compound (BPC), a protein produced in the stomach lining. First characterized by Predrag Sikirić's group at the University of Zagreb in the early 1990s.

Copper tripeptide

GHK-Cu

A copper-binding tripeptide — glycyl-L-histidyl-L-lysine coordinated to a divalent copper ion. Isolated from human plasma by Loren Pickart, 1973.

Thymosin β-4 fragment

TB-500

A synthetic peptide corresponding to the acetylated N-terminal fragment of thymosin β-4 (TMSB4X), a 43-amino-acid actin-binding protein originally isolated from thymic tissue. Characterized by Allan Goldstein and colleagues at George Washington University, 1980s onward.

Method

Sources over slogans.

Every entry starts with the facts you can check — the chemical name, the formula, the weight, and the year it was first made or found. We count the published studies on PubMed and update those numbers every quarter. Nothing goes on the shelf without at least one review paper and one original study linked, so you can go read them.

Where a lab report exists, we link straight to the vendor's public COA page rather than quoting it. The testing lab is ILS Labs. Anything tested before 2024 is kept but flagged as older. We do not repeat marketing copy.

About

Who writes this.

MyPepShelf is an independent publication about research peptides. We read the primary literature, verify third-party COAs, and publish notes on what we find. We do not sell, dispense, or prescribe.

We earn a commission when you buy through our vendor links. It's how the site pays for itself. It's also why we tell you when a vendor ships junk — the second we recommend something bad, we lose the trust that pays the bills.
