Glossary

Key terms and definitions used in peptide research, lab testing, and quality assurance.

A

Amino Acid

biology

Organic molecules that serve as building blocks for peptides and proteins. There are 20 standard amino acids used in biological protein synthesis.

B

Bacteriostatic Water

equipment

Sterile water containing 0.9% benzyl alcohol as a preservative. Used for reconstituting lyophilized peptides and allows multiple withdrawals from the same vial.

Bioavailability

biology

The proportion of a substance that enters systemic circulation and is available to produce an active effect. Injection routes typically offer higher bioavailability than oral administration.

BPC-157

biology

Body Protection Compound-157, a pentadecapeptide (15 amino acids) derived from human gastric juice. Researched for tissue repair and wound healing properties.

C

Certificate of Analysis (COA)

regulation

A document from a qualified testing laboratory that confirms a product meets its specification. Includes identity, purity, potency, and contaminant testing results.

cGMP

regulation

Current Good Manufacturing Practice. FDA regulations ensuring pharmaceutical products are consistently produced and controlled according to quality standards.

Cycle

procedure

A defined period during which a research compound is administered, typically followed by a rest period. Cycle lengths vary by compound and research protocol.

D

Dalton (Da)

chemistry

A unit of molecular mass roughly equal to the mass of a hydrogen atom. Peptides typically range from 500 to 5,000 daltons.

Desiccant

equipment

A hygroscopic substance used to maintain a dry environment. Often included in peptide packaging to protect lyophilized powders from moisture.

E

Endotoxin

biology

Lipopolysaccharides found in the outer membrane of gram-negative bacteria. Testing for endotoxins is a critical quality control step for injectable compounds.

Epithalon

biology

A synthetic tetrapeptide (Ala-Glu-Asp-Gly) studied for its effects on telomerase activation and potential anti-aging properties.

G

GLP-1

biology

Glucagon-Like Peptide-1, an incretin hormone involved in glucose metabolism and appetite regulation. GLP-1 receptor agonists are widely researched for metabolic applications.

GMP

regulation

Good Manufacturing Practice. Quality assurance standards ensuring products are consistently produced and controlled to appropriate quality standards.

H

Half-Life

biology

The time required for a substance's concentration to decrease by half. Determines dosing frequency in research protocols.

Heavy Metals Testing

regulation

Analysis for toxic metals such as lead, mercury, arsenic, and cadmium. Essential quality control for research compounds to ensure they are free from contamination.

HPLC

chemistry

High-Performance Liquid Chromatography. An analytical technique used to separate, identify, and quantify components in a mixture. The gold standard for determining peptide purity.

I

In Vitro

procedure

Latin for 'in glass.' Refers to studies performed outside a living organism, such as in test tubes or cell cultures.

In Vivo

procedure

Latin for 'in the living.' Refers to studies performed within a living organism.

Ipamorelin

biology

A pentapeptide growth hormone secretagogue that selectively stimulates GH release without significantly affecting cortisol or prolactin levels.

L

Lyophilized

procedure

Freeze-dried. A preservation process that removes water from a frozen product under vacuum. Lyophilized peptides are more stable and have longer shelf lives than liquid formulations.

M

Mass Spectrometry (MS)

chemistry

An analytical technique that measures the mass-to-charge ratio of ions. Used alongside HPLC to confirm peptide identity and detect impurities.

mcg (Microgram)

chemistry

One millionth of a gram (0.001 mg). Many peptide dosages are measured in micrograms.

Molecular Weight

chemistry

The sum of the atomic weights of all atoms in a molecule, measured in daltons. Determines a peptide's classification and influences its biological activity.

MOTS-c

biology

Mitochondrial Open reading frame of the Twelve S rRNA type-c. A mitochondrial-derived peptide researched for metabolic regulation and exercise mimetic effects.

N

NAD+

biology

Nicotinamide Adenine Dinucleotide. A coenzyme essential for cellular energy production, DNA repair, and sirtuin activation. Levels decline with age.

P

Peptide

biology

A short chain of amino acids (typically 2-50) linked by peptide bonds. Smaller than proteins, peptides serve as signaling molecules in biological systems.

Peptide Bond

chemistry

The chemical bond formed between the carboxyl group of one amino acid and the amino group of another during protein synthesis.

Purity

chemistry

The percentage of the desired compound in a sample, as determined by HPLC analysis. Research-grade peptides typically have 98%+ purity.

R

Reconstitution

procedure

The process of adding a diluent (usually bacteriostatic water) to a lyophilized powder to create a solution. Proper reconstitution technique is critical for compound integrity.

S

Secretagogue

biology

A substance that promotes the secretion of another substance. Growth hormone secretagogues stimulate the pituitary gland to release growth hormone.

Sterility

regulation

The absence of viable microorganisms. Injectable research compounds must pass sterility testing to ensure freedom from bacterial and fungal contamination.

Subcutaneous (SubQ)

procedure

Beneath the skin. Subcutaneous injection delivers a compound into the fatty tissue layer between the skin and muscle.

T

TB-500

biology

A synthetic fragment of Thymosin Beta-4, a naturally occurring peptide involved in tissue repair, cell migration, and anti-inflammatory responses.

Telomerase

biology

An enzyme that adds DNA sequence repeats to the ends of chromosomes (telomeres). Researched for its potential role in cellular aging and longevity.

Third-Party Testing

regulation

Quality analysis performed by an independent laboratory not affiliated with the manufacturer. Provides unbiased verification of product identity, purity, and safety.

U

USP

regulation

United States Pharmacopeia. A nonprofit organization that sets quality standards for medicines, dietary supplements, and food ingredients.
