General
Foundation
What Is a Research Peptide?
Peptides are short chains of amino acids — the building blocks of proteins. Research peptides are synthetic compounds studied in laboratory settings for their biological activity.
Handling
Reconstitution
Most lyophilized (freeze-dried) peptides require reconstitution with bacteriostatic water before use in a research setting. Proper technique ensures stability and accurate concentration.
Storage
Storage Guidelines
Peptides are sensitive to heat, light, and humidity. Lyophilized peptides should be stored at −20°C. Once reconstituted, refrigerate at 2–8°C and use within 28 days.
GLP & Metabolic Peptides
GLP-1 Agonist
Semaglutide
A long-acting GLP-1 receptor agonist extensively studied for its role in metabolic homeostasis, appetite regulation, and cellular energy balance.
Dual GIP/GLP-1 Agonist
Tirzepatide
A dual GIP and GLP-1 receptor agonist. Research focuses on its effects on insulin sensitivity, lipid metabolism, and energy homeostasis.
Triple Agonist
Retatrutide
A triple GLP-1, GIP, and glucagon receptor agonist. Among the newest compounds in metabolic research, studied for effects on energy expenditure and adipose tissue.
hGH Fragment
AOD-9604
A modified fragment of human growth hormone (residues 176–191). Research focuses specifically on lipolytic activity without the growth-promoting effects of full hGH.
Mitochondrial Peptide
MOTS-c
A mitochondrial-derived peptide that regulates metabolic homeostasis. Research focuses on insulin sensitivity, exercise response, and cellular aging pathways.
Growth Hormone Peptides
GHRH Analogue
Tesamorelin
A GHRH analogue that stimulates pulsatile growth hormone release. Research examines its role in visceral adipose reduction and IGF-1 axis regulation.
GH Secretagogue
Ipamorelin
A selective ghrelin receptor agonist. Research focuses on pulsatile GH release with minimal effect on cortisol and prolactin compared to other secretagogues.
Long-Acting GHRH
CJC-1295
A long-acting GHRH analogue studied for extended half-life via Drug Affinity Complex (DAC) technology and sustained GH/IGF-1 elevation in preclinical models.
Combination
CJC-1295 / Ipamorelin
A combined GHRH analogue and secretagogue. Research examines synergistic GH pulse amplification — the GHRH analogue sets the pulse frequency, ipamorelin amplifies the release.
Tissue & Repair Peptides
Gastric Pentadecapeptide
BPC-157
Derived from a human gastric protein. Extensively studied in preclinical models for tissue repair, angiogenesis, and gastrointestinal integrity.
Thymosin Fragment
TB-500
A synthetic peptide fragment of Thymosin Beta-4. Research focuses on actin binding, cell migration, and wound healing mechanisms in preclinical models.
Combination
BPC-157 + TB-500
A frequently studied pairing in preclinical models. BPC-157 supports local tissue signaling while TB-500 contributes systemic actin regulation and cell mobility.
Copper Peptides
Copper Complex
GHK-Cu
A naturally occurring copper peptide found in human plasma. Research areas include collagen synthesis stimulation, antioxidant activity, and tissue regeneration signaling.
Tripeptide Complex
AHK-Cu
A tripeptide copper complex. Research explores its role in hair follicle biology, scalp microcirculation, and extracellular matrix remodeling.
