Research peptide library.

How to store, verify and source research-grade material. Written as reference, with citations and without claims.

What is a peptide?
What is a peptide, in the vocabulary that every specification sheet, sequence line and certificate in this library already assumes. This is the page to read first.
GLP-1 peptide
The GLP-1 peptide this catalogue sells as GLP-1 S is an engineered analogue of the hormone it shares a name with, registered under CAS 910463-68-2. This page states what the molecule is, how the analogue and the hormone differ, and what our single published certificate actually says.
GLP-3 RT peptide
The GLP-3 RT peptide is a 39-residue acylated chain registered under CAS 2381089-83-2. This page states what the molecule is, how a chain that long is built, and what the certificates we publish for it actually say.
What is in the KLOW peptide blend
The KLOW peptide blend is four separate molecules sharing one vial, which means four identities to describe and four assays to read rather than one of each.
What is the GLOW peptide blend?
The GLOW peptide is not one peptide. GLOW is a product name for three molecules dried into a single vial, 70mg in total, in a ratio fixed before it was sealed.
NAD+ peptide: a coenzyme, not a peptide
NAD+ peptide is how the compound is usually searched for, and the word peptide is the wrong word. NAD+ is a dinucleotide coenzyme with no amino acids in it at all.
Ipamorelin peptide
The ipamorelin peptide contains three pieces no natural protein would supply. Read the sequence and the rest follows: this is a designed molecule, not a fragment of anything, and its identity is a matter of registry record.
What is the MOTS-c peptide?
The MOTS-c peptide has a gene, and the gene is not in the nucleus. That is the first unusual thing about it, and most of the reason 16 amino acids were worth naming.
GHK-Cu copper peptide
A GHK-Cu copper peptide vial is blue, and every other vial in this catalogue is white. The colour is not a dye. It is the evidence that the complex formed.
The BPC-157 peptide
The BPC-157 peptide is fifteen residues long, and seven of those residues are proline or glycine. For a chain this short, that composition is the most interesting thing about it.
Tesamorelin peptide
The tesamorelin peptide is the whole 44-residue growth-hormone-releasing hormone sequence with one small group attached at the front. That group is the point of the molecule.
Peptides made in the USA
Peptides made in the USA is one of the most common claims in this category and one of the least specific. It can describe four different stages, and usually only one is true.
How to vet a research peptide supplier
Any research peptide supplier can publish a purity figure. These eight checks tell you whether there is a measurement behind it.
Tesamorelin vs sermorelin vs ipamorelin
Tesamorelin vs sermorelin is a comparison between two versions of the same idea. Add ipamorelin and the comparison changes category entirely.
GLOW vs KLOW
GLOW vs KLOW is a question with a precise answer, because the difference between the two blends is a single named component. There is a larger question underneath it, because neither name is a formulation standard.
What is TB-500?
What is TB-500, and why is it constantly confused with the protein it comes from? The answer is a matter of seven amino acids against forty-three.
BPC-157 vs TB-500
BPC-157 vs TB-500 is usually asked as though the two were variants of one thing. They are unrelated molecules with different lengths, masses and origins.
What lyophilized powder is
Lyophilized powder, lyophilised in British spelling, is what almost every peptide arrives as. The process behind it explains most of how the vial should be treated.
How to store peptides
How to store peptides decides how much of what you paid for is still there when you come to use it. The rules are simple, the chemistry behind them is specific, and the mistakes are expensive.
Peptide purity testing: the methods, the laboratories and what they cost
Peptide purity testing is not one test. It is a short panel of quite different measurements run on different instruments, and knowing which is which tells you how much a certificate is worth.
Peptide purity, and what the percentage measures
Peptide purity is quoted as a single number on every listing in this category. That number is measuring something quite specific, and it is not what most buyers assume.
How to read a peptide certificate of analysis
A peptide certificate of analysis is the only document that connects the vial in your hand to a measurement. Most buyers glance at one number on it and miss the three that matter.
Bacteriostatic water for peptides
Bacteriostatic water for peptides is the default diluent for a straightforward reason: it is the only one that lets a multi-milligram vial be used more than once.
Bacteriostatic water storage and shelf life
Bacteriostatic water storage is simpler than most people expect, and the 28-day figure everyone quotes is measuring something quite specific.
Sterile water vs bacteriostatic water
Sterile water vs bacteriostatic water is a question about one ingredient and one consequence: whether the vial can be opened more than once. The labels answer it in figures.
What is bacteriostatic water?
What is bacteriostatic water, exactly? It is one ingredient away from ordinary sterile water, and that one ingredient is the entire reason it exists.

Every claim here has a document behind it

Each lot is assayed by an independent laboratory and its certificate published against the number printed on the vial, before it ships.
