BPC-157 + TB-500 Blend

The BPC-157 and TB-500 research blend combines two synthetic peptides commonly investigated in laboratory models involving cellular repair, tissue remodeling, angiogenic signaling, inflammatory responses, and recovery following experimental tissue injury. BPC-157 is a synthetic 15-amino-acid peptide studied primarily in preclinical models involving tendon fibroblasts, connective tissue, gastrointestinal tissue, blood-vessel signaling, and cellular responses to injury. TB-500 is a synthetic fragment associated with thymosin beta-4 research. Laboratory studies involving thymosin beta-4 and related fragments have examined actin regulation, cell migration, angiogenesis, tissue remodeling, and wound-repair pathways. Findings involving full-length thymosin beta-4 should not automatically be attributed to the TB-500 fragment.

GLP-3

Known a synthetic, long-acting peptide engineered to activate the glucose-dependent insulinotropic polypeptide, glucagon-like peptide-1, and glucagon receptors. It incorporates molecular modifications designed to support albumin binding and extended activity in experimental formulations. Used in qualified research settings to examine triple-receptor signaling, glucose and lipid metabolism, pancreatic endocrine pathways, appetite-related signaling, energy expenditure, gastric-motility models, adipose-tissue biology, and metabolic biomarkers. Compound type: Synthetic acylated peptide Peptide length: 39 amino acids Research class: Triple GIP/GLP-1/glucagon receptor agonist Form: Lyophilized research material Purity: Refer to the lot-specific Certificate of Analysis Testing: Identity and purity documentation available by lot Storage: Store according to the conditions printed on the product label and Certificate of Analysis Research Applications May be used in qualified laboratory investigations involving: GIP-receptor signaling GLP-1-receptor signaling Glucagon-receptor signaling Triple-receptor pharmacology Glucose-dependent insulin-secretion pathways Pancreatic beta-cell and alpha-cell function Glucose and glucagon regulation Appetite, satiety and energy-balance signaling Gastric-motility research Adipocyte and lipid-metabolism pathways Energy-expenditure and substrate-utilization models Body-composition and metabolic-marker studies Comparative incretin and multi-agonist research.

KLOW (CU50 + TB10 + BC10 + KPV10)

KLOW — Research Use Only KLOW is a four-compound research blend containing GHK-Cu, BPC-157, TB-500, and KPV. The formulation combines research materials investigated in laboratory models involving extracellular-matrix remodeling, cellular migration, angiogenesis, collagen signaling, inflammatory pathways, gastrointestinal biology, and tissue-repair mechanisms. Each component has a distinct experimental profile. GHK-Cu is a copper-binding tripeptide studied in collagen and skin-biology models. BPC-157 is a synthetic pentadecapeptide investigated primarily in preclinical tissue-repair and vascular-signaling research. TB-500 is a thymosin-beta-4-related research peptide examined in actin regulation and cell migration. KPV is a melanocortin-derived tripeptide studied in inflammatory-signaling and intestinal-cell models. Product Information Product: KLOW Total content: 80 mg GHK-Cu: 50 mg BPC-157: 10 mg TB-500: 10 mg KPV: 10 mg Compound type: Multi-peptide research blend Research class: Tissue-remodeling and inflammatory-signaling blend Form: Lyophilized research material Purity: Refer to the lot-specific Certificate of Analysis Testing: Identity and purity documentation available by lot Storage: Store according to the conditions printed on the product label and Certificate of Analysis Research Applications KLOW may be used in qualified laboratory investigations involving: Collagen and elastin-associated pathways Extracellular-matrix organization and remodeling Fibroblast, keratinocyte, and endothelial-cell activity Cellular migration and actin regulation Angiogenesis and vascular-signaling models Inflammatory cytokine signaling NF-κB and MAP-kinase-associated pathways Gastrointestinal and intestinal-epithelial-cell models PepT1-mediated peptide-transport research Skin and connective-tissue biology Oxidative-stress and cellular-repair mechanisms Copper-dependent enzyme activity Multi-compound interaction and pathway research Because KLOW combines four research compounds, findings involving the complete blend should not be assumed to equal findings reported for its individual components. Important Notice For research use only. Not for human or veterinary use. This product is supplied exclusively for controlled laboratory research by qualified professionals. It is not intended for diagnosis, treatment, prevention, personal administration, pharmacy compounding, cosmetic treatment, wound care, gastrointestinal treatment, injury recovery, or any other clinical purpose. No dosing, reconstitution, administration, cycling, injury-recovery, skin-care, gastrointestinal, or therapeutic guidance is provided or implied. Researchers are responsible for appropriate handling and compliance with all applicable requirements.

Tesamorelin

Tesamorelin — Research Use Only Tesamorelin is a synthetic 44-amino-acid analog of human growth hormone–releasing hormone, also known as growth hormone–releasing factor. The molecule contains the complete human GHRH(1–44) sequence with an N-terminal trans-3-hexenoyl modification designed to increase stability against enzymatic degradation. Tesamorelin is used in qualified research settings to investigate GHRH-receptor signaling, pulsatile growth-hormone secretion, IGF-1 pathways, adipocyte biology, lipid metabolism, and body-composition measurements in defined experimental models. Product Information Product: Tesamorelin Compound type: Synthetic GHRH/GRF analog Peptide length: 44 amino acids Structural modification: N-terminal trans-3-hexenoyl group Molecular weight: Approximately 5,135.9 Da as the free-base equivalent Form: Lyophilized research material Purity: Refer to the lot-specific Certificate of Analysis Testing: Identity and purity documentation available by lot Storage: Store according to the conditions printed on the product label and Certificate of Analysis Research Applications Tesamorelin may be used in qualified laboratory investigations involving: GHRH-receptor activation Pituitary growth-hormone secretion Growth-hormone pulse dynamics IGF-1 and IGFBP-3 signaling Adipocyte and lipid-metabolism pathways Visceral and subcutaneous adipose-tissue models Body-composition measurement methods Glucose and metabolic-marker research GH-axis feedback and endocrine signaling Important Regulatory Distinction Tesamorelin is the active ingredient in the FDA-approved prescription products EGRIFTA SV and EGRIFTA WR, which are indicated to reduce excess abdominal fat in adults with HIV-associated lipodystrophy. The prescribing information specifically states that these products are not indicated for general weight-loss management. The tesamorelin offered by Pep Research Labs is an independent research-use-only material. It is not EGRIFTA, is not an FDA-approved drug product, and must not be represented as equivalent or interchangeable with either approved prescription formulation. Important Notice For research use only. Not for human or veterinary use. This product is supplied exclusively for controlled laboratory research by qualified professionals. It is not intended for diagnosis, treatment, prevention, personal administration, compounding, weight-loss management, bodybuilding, or any other clinical purpose. No dosing, reconstitution, administration, fat-loss, muscle-building, anti-aging, or therapeutic guidance is provided or implied. Researchers are responsible for appropriate handling and compliance with all applicable requirements.
