Metabolic Research Peptides UK — AOD-9604 and MOTS-C for UK Laboratory Research
Metabolic research peptides UK suppliers serve one of the most scientifically active research categories in current laboratory literature. The compounds in this category act on pathways involved in adipocyte biology and mitochondrial signalling, two widely studied research areas in cellular metabolism.
Ascend Peptides UK supplies the two principal metabolic research peptides in the UK catalogue: AOD-9604 (a lipolytic growth hormone fragment) and MOTS-C (a mitochondrial-derived signalling peptide). Both compounds are HPLC-verified at ≥98% purity, LC-MS confirmed for molecular identity, and independently tested by Janoshik with a publicly verifiable Certificate of Analysis on every batch.
This page sets out the scientific and procurement details for both compounds, what each is, how they differ mechanistically, how they are used in UK laboratory research, and how to source metabolic research peptides that UK suppliers offer with full documentation transparency.
The two compounds cover the two principal intervention points in laboratory metabolic research: adipocyte and lipolytic activity research (AOD-9604) and mitochondrial-nuclear signalling research (MOTS-C). Researchers running multi-compound metabolic programmes typically use both together as independent variables within the same experimental design. Metabolic compounds sit alongside the rest of our research peptides in the UK catalogue.

What Are Metabolic Research Peptides?
Metabolic research peptides are synthetic compounds used in laboratory research to study pathways involved in lipid metabolism, adipocyte biology, and mitochondrial signalling. In the Ascend Peptides UK catalogue, the metabolic research peptide category covers two compounds, each representing a distinct mechanistic class:
- Lipolytic growth hormone fragments peptides derived from the C-terminal region of human growth hormone with selective effects on adipocyte biology. AOD-9604 (Anti-Obesity Drug 9604) is the standard research compound in this class, a 16-amino acid fragment of human growth hormone covering residues 177–191.
- Mitochondrial-derived signalling peptides are encoded within the mitochondrial genome and participate in metabolic signalling. MOTS-C (Mitochondrial Open Reading Frame of the 12S rRNA-c) is the standard research compound in this class, a 16-amino acid peptide encoded within the mitochondrial 12S rRNA gene.
The mechanistic distinction matters because each compound represents a different point of intervention in metabolic biology. AOD-9604 acts at the adipocyte level on lipolytic pathways. MOTS-C acts on mitochondrial-nuclear signalling and AMPK pathway activation.
Researchers select compounds based on which pathway is the experimental focus or use both together when the research design covers multiple intervention points within the same metabolic cascade.
AOD-9604 Research Peptide UK Lipolytic Growth Hormone Fragment
AOD-9604 (Anti-Obesity Drug 9604) is a 16-amino acid synthetic peptide corresponding to the C-terminal region of human growth hormone, covering residues 177–191, with a tyrosine residue added at the N-terminus for analytical and synthetic stability. Molecular formula C78H123N23O23S2, molecular weight approximately 1815.06 Da.
AOD-9604 is a structurally distinct lipolytic peptide research compound in the metabolic category, which carries the lipolytic activity associated with the C-terminal portion of growth hormone with reduced growth hormone receptor signalling activity compared with full-length hGH. This selectivity is the defining research property of AOD-9604. For a complete mechanistic background, see the AOD-9604 research peptide guide on the Ascend Peptides UK research blog.
Research Applications of AOD-9604
In UK metabolic research literature, AOD-9604 is the standard reference compound for lipolytic activity research in adipocyte cell culture models. Documented research applications include adipocyte triglyceride mobilisation research, fatty acid release research, lipolytic enzyme expression research, and growth hormone fragment selectivity research all in in-vitro cellular research models.
AOD-9604 is also studied alongside MOTS-C in research programmes that examine both the adipocyte-level and the mitochondrial-level components of metabolic signalling within a single experimental design.
AOD-9604 is supplied by Ascend Peptides UK with HPLC purity verified at ≥98% by Janoshik laboratory, LC-MS molecular identity confirmation, and a batch-specific Certificate of Analysis available pre-purchase.
Reconstitute with BP-grade bacteriostatic water and store at −20°C. Browse the live AOD-9604 product page for batch documentation and same-day UK dispatch.
MOTS-C Research Peptide UK — Mitochondrial-Derived Metabolic Signalling Peptide
MOTS-C (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a 16-amino acid peptide encoded within the mitochondrial 12S rRNA gene, one of the first identified mitochondrial-derived peptides (MDPs) in published research literature. Molecular formula C100H152N28O22S2, molecular weight approximately 2174.55 Da.
MOTS-C is the most extensively characterised member of the mitochondrial-derived peptide class and the standard research compound for studies of mitochondrial-nuclear signalling and AMPK pathway activation. For complete scientific detail, see the MOTS-C research peptide guide on the Ascend Peptides UK research blog.
Research Applications of MOTS-C
Research applications of MOTS-C in published UK and international literature include AMPK pathway activation studies, mitochondrial-nuclear signalling research, metabolic regulation research at the cellular level, and ageing biology research at the mitochondrial level. MOTS-C is the standard research compound when the experimental focus is the mitochondrial signalling component of metabolic biology.
It is structurally and mechanistically distinct from lipolytic fragments such as AOD-9604, which act at the adipocyte level rather than the mitochondrial level, making the two compounds complementary research tools within the same metabolic research programme.
MOTS-C is supplied by Ascend Peptides UK with HPLC purity verified at ≥98% by Janoshik laboratory, LC-MS molecular identity confirmation, and a batch-specific Certificate of Analysis. Browse the live MOTS-C product page for batch documentation and same-day UK dispatch.

Buy Metabolic Research Peptides UK — Documentation Buyer Framework
UK researchers buying metabolic research peptides should apply the same documentation framework to every supplier, every batch, and every order. The framework has four steps:
- Step 1 — Verify the Certificate of Analysis is batch-specific and publicly accessible. A generic CoA that does not name the specific lot number is not a real CoA.
- Step 2 — Confirm the HPLC purity result is ≥98% and the analytical method is named. “HPLC tested” without a specific purity figure is not a result.
- Step 3 — Confirm LC-MS molecular identity is reported. HPLC alone confirms purity but does not confirm that the compound is the expected molecule. LC-MS is the identity confirmation step.
- Step 4 — Confirm storage and dispatch standards. Lyophilised powder format, −20°C cold chain storage, and same-day or next-day UK dispatch with insulated packaging.
Ascend Peptides UK meets all four standards on every batch of AOD-9604 and MOTS-C supplied. The Janoshik Certificate of Analysis is publicly accessible, the HPLC purity figure is stated on every batch, the LC-MS molecular identity is reported, and all compounds are dispatched same-day before 16:00 GMT in temperature-controlled packaging.

Metabolic Research Peptides UK — Frequently Asked Questions
What are metabolic research peptides?
Metabolic research peptides are synthetic compounds used in laboratory research to study pathways involved in adipocyte biology, lipid metabolism, and mitochondrial signalling. In the Ascend Peptides UK catalogue, the category covers AOD-9604 (a lipolytic growth hormone fragment) and MOTS-C (a mitochondrial-derived signalling peptide).
What is AOD-9604, and what makes it different from full-length hGH?
AOD-9604 is a 16-amino acid fragment of human growth hormone covering residues 177–191, with a tyrosine residue added at the N-terminus. The defining research property of AOD-9604 is selectivity — it carries the lipolytic activity associated with the C-terminal portion of hGH without engaging the growth hormone receptor signalling pathway. This makes it the standard research compound for isolated lipolytic activity research in adipocyte cell models.
What is MOTS-C, and why is it studied?
MOTS-C (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a 16-amino acid peptide encoded within the mitochondrial 12S rRNA gene — one of the first identified mitochondrial-derived peptides. MOTS-C is studied for its role in mitochondrial-nuclear signalling, AMPK pathway activation, and metabolic regulation. It is the most characterised member of the mitochondrial-derived peptide class.
Can AOD-9604 and MOTS-C be studied together?
Yes — they target mechanistically distinct intervention points within the metabolic cascade. AOD-9604 acts at the adipocyte level on lipolytic pathways, while MOTS-C acts at the mitochondrial level on signalling pathways. The two compounds are routinely used together as independent variables in multi-compound metabolic research programmes covering both adipocyte and mitochondrial intervention points.
What is the WADA status of metabolic research peptides?
AOD-9604 is subject to WADA monitoring under categories covering growth hormone fragments and metabolic modulators. MOTS-C is not currently a WADA-prohibited substance but is supplied strictly for in-vitro laboratory research. Researchers should consult the current WADA Prohibited List for the most up-to-date classification of any specific compound.
