GLY–HIS–LYS · Cu2+
GHK-Cu 100mg
MW 403.9 · TRIPEPTIDE–COPPER COMPLEX
GHK-Cu is a naturally occurring copper-binding tripeptide investigated in laboratory models of extracellular matrix regulation, collagen-related signalling and tissue remodelling. Findings are dependent on experimental conditions and do not establish clinical effectiveness.
Copper-binding tripeptide investigated in laboratory models of matrix regulation and tissue remodelling.

GEPPPGKPADDAGLV
BPC-157 10mg
MW 1419.5 · 15 RESIDUES · PENTADECAPEPTIDE
BPC-157 is a synthetic pentadecapeptide investigated in preclinical models involving tissue responses, angiogenic signalling and gastrointestinal physiology. Most published efficacy evidence is preclinical, and therapeutic safety and effectiveness in humans have not been established.
Synthetic pentadecapeptide investigated in preclinical models. Human safety and effectiveness not established.

Ac-LKKTETQ
TB-500 10mg
MW 889.0 · THYMOSIN β4-ASSOCIATED FRAGMENT
TB-500 is a synthetic peptide associated with a fragment of thymosin beta-4 and investigated in molecular and cellular research. Findings involving full-length thymosin beta-4 cannot automatically be attributed to the shorter peptide fragment.
Synthetic peptide associated with a thymosin β4 fragment, investigated in molecular and cellular research.

LY3437943
Retatrutide 10mg
MW 4731 · GLP-1 / GIP / GLUCAGON TRIAGONIST
Retatrutide (LY3437943) is an investigational peptide designed to activate GLP-1, GIP and glucagon receptors. It has been evaluated in clinical research investigating metabolic and weight-related outcomes. Clinical development and regulatory status are subject to change.
Investigational GLP-1 / GIP / glucagon receptor agonist evaluated in clinical research.

trans-3-HEXENOYL-hGRF(1–44)-NH2
Tesamorelin 20mg
MW 5135.9 · 44 RESIDUES · GHRH ANALOGUE
Tesamorelin is a synthetic analogue of growth-hormone-releasing hormone (GHRH). Specific pharmaceutical formulations have received US regulatory approval for defined medical indications. These approvals do not apply to independently supplied research-grade preparations.
Synthetic GHRH analogue. Approvals for specific formulations do not apply to research preparations.

MRWQEMGYIFYPRKLR
MOTS-c 40mg
MW 2174.6 · 16 RESIDUES · MITOCHONDRIAL-DERIVED PEPTIDE
MOTS-c is a mitochondrial-derived peptide investigated in preclinical studies involving metabolic regulation, cellular stress responses and AMPK-associated signalling. Its safety and clinical effectiveness in humans remain insufficiently established.
Mitochondrial-derived peptide investigated in preclinical studies of metabolic regulation.

Scope
Quadra Biotech supplies reference materials to laboratories, universities and contract research organisations. Products are intended exclusively for legitimate laboratory research. They are not intended for human or veterinary administration, clinical treatment, supplementation or self-experimentation. Scientific descriptions are provided for research information and do not constitute medical advice or establish therapeutic safety or efficacy.
Evidence
Each compound carries its evidence status in the same viewport as its name: approved formulation, topical, investigational or preclinical. Preclinical evidence is kept distinct from human clinical findings. Where the literature is thin, we say so. Where a mechanism is described, it is cited to a primary source you can read yourself.
Limits
We publish no dosing, no administration routes and no protocols. Storage and reconstitution conditions only. Regulatory status varies by compound, formulation, intended use and jurisdiction. Any approvals granted to pharmaceutical products do not extend automatically to the research materials supplied by Quadra Biotech.
Quadra Biotech makes no therapeutic claims. Product availability and shipping eligibility depend on the selected destination, applicable regulations and purchaser eligibility. Orders may be declined where lawful supply cannot be established. Research use & product information.
