GHK-Cu (Copper Peptide)
A copper peptide made of three amino acids, including glycine, histidine, and lysine, that is bound to a copper ion. It is one of the most studied copper peptides in molecular biology research.
GHRH (Growth Hormone-Releasing Hormone)
A naturally occurring hormone produced in the hypothalamus that signals the pituitary gland to release growth hormone.
GHRH (Growth Hormone-Releasing Peptide)
A category of synthetic peptides studied for their interactions with the ghrelin receptor and their effects on growth hormone secretion in research models.
Growth Hormone
A protein produced by the pituitary gland that plays a key role in growth, metabolism, and cellular repair.
H
Hormones
Chemical messengers produced by glands in the body that travel through the bloodstream and tell cells what to do.
HPLC
High-performance liquid chromatography is a gold standard method for measuring how pure a research peptide is. An HPLC machine pushes a liquid sample through a special column under high pressure.
HPLC Chromatogram
The graph on a Certificate of Analysis shows the results of an HPLC test. The target compound appears as the tallest peak, and any impurities show up as smaller peaks.
I
IGF-1 LR3
A modified version of the naturally occurring IGF-1 peptide, extended with a 13-amino acid sequence at one end. The LR3 modification gives it different properties compared to native IGF-1, making it a useful research tool in molecular biology.
Independent Testing
Quality verification is done by a laboratory that has no financial connection to the company selling the compound. This matters because a supplier testing its own products has an obvious conflict of interest.
Ipamorelin
A five-amino acid synthetic peptide with a molecular weight of approximately 711.9 Da is commonly studied in laboratory research. It is often paired with CJC-1295 as a blend compound.
ISO Certification
An internationally recognized quality management standard. When a peptide manufacturer holds ISO certification, it confirms that their facility operates within a documented quality system.
K
Kilodalton
Equal to 1,000 daltons. Larger peptide compounds are measured in kilodaltons because the numbers are more manageable.
L
Lyophilization
The process of removing moisture from a compound involves first freezing it, then using a vacuum to convert the ice directly into vapor. Most research-grade peptides are supplied in lyophilized form because it significantly extends shelf life and preserves compound integrity during transit.
M
Mass Spectrometry
A laboratory technique that confirms the exact molecular identity of a compound by measuring its mass. Think of it as a fingerprint check that tells you whether what is in the vial actually matches the molecular weight of the compound it is supposed to be.
Metabolism
The sum of all chemical processes that keeps the body running converting food into energy, building and breaking down molecules, and managing waste.
Molecular Weight
A measure of how heavy a molecule is, expressed in daltons or grams per mole. Every peptide has a precise theoretical molecular weight based on its amino acid sequence.
Molecules
The smallest units of a substance that still carry its chemical identity are made up of two or more atoms bonded together. Peptides are molecules, and understanding their molecular structure is the starting point for analyzing their behavior in research settings.
Muscle Growth
A biological process involving increased muscle protein synthesis, typically studied in research through the lens of growth hormone signaling, cellular repair, and anabolic pathways.
P
Peptide
A short chain of amino acids linked together acts as a signaling molecule to influence processes like hormonal release, tissue repair, and metabolism.
Peptide Bond
It is a strong, covalent chemical bond that links amino acids together to form proteins and peptides.
Peptide Calculator
A tool used to calculate how much solvent to add to a lyophilized peptide powder to reach a desired concentration.
Peptide Serum
A liquid formulation containing one or more peptide compounds in a carrier solution, often used in topical or delivery-focused research applications.
Peptide Synthesis
The laboratory process of building a peptide chain involves linking amino acids together in a specific sequence.
Polypeptides
A longer peptide chain, typically containing more than 10 amino acids. The distinction between a peptide and a polypeptide is based primarily on chain length.
Proteins
Large biological molecules are made up of long chains of amino acids folded into complex three-dimensional structures. Proteins carry out most of the work inside cells.
Purity
A measure of how much of a compound sample is the actual target molecule, expressed as a percentage. If a peptide is 99.5% pure, that means 99.5% of what is in the vial is the compound you ordered.
Q
Quality Control
The set of procedures a supplier uses to confirm that a compound meets defined standards before it ships. For research peptides, this includes HPLC purity testing, mass spectrometry identity confirmation, and endotoxin screening.
R
Reconstitution
The process of adding a liquid, usually bacteriostatic water or another appropriate solvent, to a lyophilized peptide powder to turn it back into a solution ready for research use.
Research Grade
A classification indicating that a compound was made and tested to a standard suitable for scientific research.
S
Shelf Life
The length of time a peptide compound remains stable and suitable for research use under appropriate storage conditions.
Storage Conditions
The specific temperature, light, and humidity requirements that keep a peptide stable over time. Most lyophilized research peptides should be stored at 2 to 8 degrees Celsius, away from light and moisture.
T
TB-300
A synthetic version of a naturally occurring 43-amino acid peptide called Thymosin Beta-4. TB-500 is a well-documented research compound frequently studied in molecular biology, particularly in relation to cellular actin dynamics.
Third-Part Testing
Testing conducted by a laboratory that has no financial connection to the company selling the compound. When an independent lab issues a Certificate of Analysis, the result carries real weight because there is no incentive to report anything other than the truth.
Tissue Repair
The biological process by which the body rebuilds and restores damaged cells and structures.
Tracebility
The ability to trace a specific compound all the way back through its production and testing history. Full traceability means your Certificate of Analysis, lot number, and shipping records all connect to the same batch.
