Research Peptide Catalog

BPC-157 (Body Protection Compound) is a pentadecapeptide derived from a protective sequence found in human gastric juice. It has been extensively studied in preclinical models for its purported regenerative effects on connective tissue, vascular formation, and gastrointestinal lining repair.

• Studied in muscle and tendon repair models
• Investigated for angiogenic activity
• Stable in gastric environment per published research

Thymosin Beta-4 is a naturally occurring 43-amino-acid peptide investigated in research settings for cellular migration, actin sequestration, and soft tissue recovery models.

• Actin-binding peptide research
• Investigated in musculoskeletal recovery models
• Studied for cardiovascular repair pathways

Sermorelin is a synthetic analogue of the first 29 amino acids of growth hormone-releasing hormone (GHRH), used in research focused on endocrine signaling and pituitary secretion patterns.

• GHRH receptor agonist studies
• Pulsatile secretion research models
• Short half-life pharmacokinetic profile

Ipamorelin is a pentapeptide ghrelin/growth hormone secretagogue receptor agonist studied for its selectivity profile in preclinical endocrine research.

• Selective GHS-R1a agonist research
• Minimal impact on cortisol/prolactin in studies
• Frequently paired with GHRH analogues in research

CJC-1295 is a modified GHRH analogue researched for prolonged half-life via DAC (drug affinity complex) technology, enabling extended endocrine signaling studies in animal models.

• Extended half-life GHRH analogue
• Studied in sustained-release research
• Investigated alongside ipamorelin in models

Epithalon is a synthetic tetrapeptide based on a pineal gland extract, investigated in cellular aging and telomerase-activity research in vitro and in animal models.

• Telomerase activity research
• Studied for circadian/endocrine modulation
• Compact peptide chain for stability research

Bremelanotide is a cyclic heptapeptide melanocortin receptor agonist with affinity for MC3-R and MC4-R, studied in preclinical neuroscience and behavioral research.

• Melanocortin receptor agonist studies
• CNS-active research peptide
• Stable cyclic peptide architecture

GHK-Cu is a naturally occurring copper-binding tripeptide widely studied for its role in extracellular matrix remodeling, fibroblast activity, and dermal regeneration research.

• Copper-binding tripeptide research
• Extensively studied in dermal repair models
• Investigated in gene-expression profiling studies

Retatrutide (LY3437943), informally referenced as GLP-3RT, is a synthetic single-molecule triple agonist targeting the GLP-1, GIP, and glucagon receptors. It has been studied in preclinical and clinical research for its effects on energy expenditure, glycemic regulation, hepatic lipid metabolism, and body-composition modulation. Its tri-receptor activity distinguishes it from earlier mono- and dual-agonists such as semaglutide and tirzepatide.

• Triple agonist: GLP-1R, GIP-R, and glucagon receptor
• Once-weekly pharmacokinetic profile in studies
• Investigated in metabolic, hepatic, and adiposity research
• Studied for energy expenditure and glycemic endpoints

MK-677 (Ibutamoren) is a non-peptidic, orally active growth hormone secretagogue that mimics ghrelin's action at the GHS-R1a receptor. It has been investigated in research settings for its ability to produce sustained, pulsatile growth hormone release and elevated IGF-1 levels over 24-hour cycles without affecting cortisol in most studies. It is frequently studied alongside GHRH analogues and selective secretagogues for comparative endocrine signaling research.

• Ghrelin / GHS-R1a receptor agonist
• Orally bioavailable — unique among GH secretagogues
• Studied for sustained 24-hour GH and IGF-1 elevation
• Long half-life (~24 hours) in pharmacokinetic studies
