Sermorelin is a synthetic analogue of the first 29 amino acids of growth-hormone-releasing hormone (GHRH 1-29), studied in research into GHRH-receptor signalling and the GH axis in experimental models.
Sermorelin is a synthetic 29-amino-acid peptide corresponding to the first 29 residues of growth-hormone-releasing hormone, GHRH (1-29). It carries the molecular formula C149H246N44O42S, a molecular weight of 3357.9 g/mol and CAS number 86168-78-7. Kovalabs supplies it as a lyophilised research peptide for laboratory use only.
It is also catalogued as GRF (1-29) and as the salt form Sermorelin acetate. In research settings it is studied as a GHRH-receptor agonist within the somatotropic (GH) axis. PubChem lists it under CID 16132413.
Sermorelin is not a controlled drug under the Misuse of Drugs Act 1971, so it is legal to buy and hold in the UK as a research chemical. Kovalabs supplies it for laboratory research use only. It is not a medicine, is not authorised for human or veterinary use, and cannot be sold for human consumption. The purchaser is responsible for lawful handling and for compliance with the rules of their institution and jurisdiction.
Each batch is released after independent analysis. Purity is assessed by HPLC at 99% or greater, and identity is confirmed against the expected mass and the verified identifiers: CAS 86168-78-7, formula C149H246N44O42S, molecular weight 3357.9 g/mol and PubChem CID 16132413. A batch certificate of analysis is available on the CoA page. Not all material described as sermorelin is equivalent, so the CoA is the reference point for what arrives.
The published literature studies Sermorelin as a GHRH-receptor agonist acting on the GH axis in pre-clinical and in-vitro models, alongside its use as an analytical reference in anti-doping work. None of this establishes a benefit, effect or outcome in humans, and it is not a licensed medicine. The mechanistic and evidence detail sits in the Sermorelin GHRH research monograph; this product page does not assess clinical evidence. See the research disclaimer for the terms of supply.
Sermorelin is supplied as a white to off-white lyophilised powder. For bench work it is typically reconstituted with a solvent such as bacteriostatic water, a standard laboratory step. Store the lyophilised solid at -20C, kept dry and protected from light; hold reconstituted material at 2-8C. It sits in the GH-axis category alongside related research peptides including Tesamorelin, Ipamorelin, CJC-1295 (no DAC) and CJC-1295 DAC. For laboratory research use only; not for human or veterinary use.
No third-party batch reports have been uploaded for this product yet. Reports are issued by independent labs after each manufacturing batch.
Store unreconstituted vials at -20°C for long-term, or refrigerated at 2-8°C for short-term use. Avoid repeated freeze-thaw cycles.
Reconstitute with bacteriostatic water down the inside wall of the vial; gently swirl to dissolve. Do not shake.
Once reconstituted, refrigerate at 2-8°C and use within 2-4 weeks. Discard if cloudy, discoloured, or particulate.
