Coded Product Names Explained
Bench Grade Peptides sells four incretin- and amylin-class research compounds under coded catalogue names: GLP-1 S, GLP-2 T, GLP-3 R and AMY-A. In the GLP names the digit is the number of receptors the molecule is built to engage (one, two or three), and each lot's third-party Certificate of Analysis states its full identity. GLP-2 T (Tirzepatide) and GLP-3 R (Retatrutide) also carry their nonproprietary names.
What does each coded name mean?
| Catalogue name | Compound class | Receptors | Product and certificates |
|---|---|---|---|
| GLP-1 S | single-receptor incretin agonist class | GLP-1 receptor | GLP-1 S product page GLP-1 S COA history |
| GLP-2 T (Tirzepatide) | dual-receptor incretin agonist class | GLP-1 and GIP receptors | GLP-2 T product page GLP-2 T COA history |
| GLP-3 R (Retatrutide) | triple-receptor incretin agonist class | GLP-1, GIP and glucagon receptors | GLP-3 R product page GLP-3 R COA history |
| AMY-A | long-acting amylin analog agonist class | amylin receptors | AMY-A product page AMY-A COA history |
- GLP-1 S
- GLP-1 S is a coded catalogue name for a research compound in the single-receptor incretin agonist class (GLP-1 receptor); its full identity is stated on the third-party Certificate of Analysis for each lot.
- GLP-2 T
- GLP-2 T is the catalogue name for Tirzepatide, a research compound in the dual-receptor incretin agonist class (GLP-1 and GIP receptors).
- GLP-3 R
- GLP-3 R is the catalogue name for Retatrutide, a research compound in the triple-receptor incretin agonist class (GLP-1, GIP and glucagon receptors).
- AMY-A
- AMY-A is a coded catalogue name for a research compound in the long-acting amylin analog agonist class (amylin receptors); its full identity is stated on the third-party Certificate of Analysis for each lot.
What do the numbers and letters in the GLP names stand for?
The digit is the number of receptors the molecule is built to engage: one for GLP-1 S (the GLP-1 receptor), two for GLP-2 T (GLP-1 and GIP receptors), three for GLP-3 R (GLP-1, GIP and glucagon receptors). It is not a hormone number. GLP-2 T is not glucagon-like peptide-2, the separate intestinal hormone, and GLP-3 R is not named after any hormone. The trailing letter is a catalogue designator. AMY-A follows the same pattern for the amylin-analog class.
The receptor count is a structural description, not a ranking: a triple agonist engages a pathway a dual agonist does not, rather than being a stronger version of it. The comparison guide mono, dual and triple incretin agonists compared covers the receptor architecture in more depth.
What is in each house blend?
Some blends are sold under a house name rather than their component list. Each resolves to the components below; the certificate for a lot reports what that lot contains.
KLOW Blend 80mg (KLOW 80): GHK-Cu / BPC-157 / TB-500 / KPV
GLOW Blend 70mg (GLOW 70): GHK-Cu / TB-500 / BPC-157
GLOW Blend 90 (GLOW 90): GHK-Cu / TB-500 / BPC-157
Metabolic Blend 120mg: NAD+ / MOTS-c / 5-Amino-1MQ

How do you confirm what a coded vial contains?
A name, coded or not, is a label. The evidence of identity is the lot’s Certificate of Analysis: match the lot number on the vial to a published certificate, then read the mass-spectrometry result against the expected molecular weight and the HPLC purity with its chromatogram. The guide to reading a peptide COA walks through each field, and the COA library lists every published lot.
Common questions about coded names
- What is GLP-1 S?
- GLP-1 S is a coded catalogue name for a research compound in the single-receptor incretin agonist class (GLP-1 receptor); its full identity is stated on the third-party Certificate of Analysis for each lot. It is supplied for laboratory research use only.
- What is GLP-2 T?
- GLP-2 T is the catalogue name for Tirzepatide, a research compound in the dual-receptor incretin agonist class (GLP-1 and GIP receptors). It is supplied for laboratory research use only.
- What is GLP-3 R?
- GLP-3 R is the catalogue name for Retatrutide, a research compound in the triple-receptor incretin agonist class (GLP-1, GIP and glucagon receptors). It is supplied for laboratory research use only.
- What is AMY-A?
- AMY-A is a coded catalogue name for a research compound in the long-acting amylin analog agonist class (amylin receptors); its full identity is stated on the third-party Certificate of Analysis for each lot. It is supplied for laboratory research use only.
- Is GLP-2 T the same as glucagon-like peptide-2?
- No. In these catalogue names the digit counts receptors: GLP-1 S engages one receptor, GLP-2 T two and GLP-3 R three. GLP-2 T is not the hormone glucagon-like peptide-2 (GLP-2), and GLP-3 R is not named after any hormone.
- Why are some compounds listed under coded names?
- Coded catalogue designations identify the product line and its receptor class. GLP-2 T (Tirzepatide) and GLP-3 R (Retatrutide) show their nonproprietary names beside the code; the others are described by class. Whatever the label says, the evidence of identity is the lot's Certificate of Analysis, chiefly its mass-spectrometry result.
- How do I confirm which molecule is in a coded vial?
- Match the lot number on the vial to its published Certificate of Analysis and read the mass-spectrometry identity result against the expected molecular weight. The COA history page for each product lists every published lot.
