What is Ipamorelin?
Ipamorelin is a synthetic pentapeptide and a selective agonist of the growth-hormone secretagogue receptor (GHS-R), the ghrelin receptor. Its sequence is Aib-His-D-2-Nal-D-Phe-Lys-NH2, with molecular formula C38H49N9O5, molecular weight 711.9 g/mol and CAS number 170851-70-4. It is a research reference compound, supplied lyophilised for laboratory use only.
The amide-capped C-terminus and the two D-amino acids distinguish it from earlier secretagogue peptides and are characteristic of its identity. Kovalabs supplies Ipamorelin as a reference material within the GH-axis research category, not as a medicine or supplement.
Is Ipamorelin legal in the UK?
Ipamorelin is not a controlled drug under the Misuse of Drugs Act 1971 and is not scheduled. It is supplied in the UK strictly as a research chemical for laboratory use only. It is not a licensed medicine, holds no marketing authorisation, and cannot be sold or supplied for human or veterinary consumption. The buyer is responsible for lawful, compliant handling under their own jurisdiction. See our research disclaimer.
How is identity and quality assured?
Each batch is released after independent testing. Purity is assessed by HPLC at 99% or greater, and identity is confirmed by HPLC retention-time matching (HPLC-RTM) against a reference standard for C38H49N9O5 (CAS 170851-70-4, PubChem CID 9831659). A batch-specific Certificate of Analysis accompanies the material; current documents are published on our CoA page. This verification is what separates a characterised reference compound from unverified material, which is why "is all Ipamorelin the same" has a clear answer: only a CoA-backed batch is.
What does the research on Ipamorelin investigate?
The published literature investigates Ipamorelin as a tool to probe GHS-R signalling and the ghrelin / growth-hormone secretagogue pathway in pre-clinical and in-vitro models. People searching for Ipamorelin benefits or effects should note that none of this establishes any benefit, effect or outcome in humans; it is not a licensed medicine and no human or veterinary application is intended or implied. The mechanistic detail and the cited studies are covered in our Ipamorelin research monograph.
How does Ipamorelin compare with CJC-1295 and sermorelin?
These are distinct molecules studied within the same GH-axis. Ipamorelin is a short GHS-R agonist pentapeptide; CJC-1295 (no DAC) and CJC-1295 (DAC) are growth-hormone-releasing-hormone analogues, as is sermorelin. The "CJC-1295 and Ipamorelin" search cluster reflects research interest in pairing two different receptor targets in laboratory study designs; this is an identity and pharmacology comparison only, not a protocol or any guidance for use in a body.
Synthesis and supply
Ipamorelin is supplied as a white to off-white lyophilised solid for reconstitution at the bench with a research solvent such as bacteriostatic water. Store lyophilised material at -20C, dry and protected from light; hold reconstituted material at 2-8C. Sold per vial as a product specification, despatched from the UK. For laboratory research use only; not for human or veterinary use.

Common questions
- What is Ipamorelin?
- Ipamorelin is a synthetic pentapeptide and a selective agonist of the growth-hormone secretagogue receptor (GHS-R, the ghrelin receptor). Its sequence is Aib-His-D-2-Nal-D-Phe-Lys-NH2, with molecular formula C38H49N9O5 and CAS number 170851-70-4. It is supplied as a lyophilised reference compound for laboratory research use only, not as a medicine or supplement.
- Is Ipamorelin legal in the UK?
- Ipamorelin is not a controlled drug under the Misuse of Drugs Act 1971 and is not scheduled. It is supplied in the UK strictly as a research chemical for laboratory use only. It is not a licensed medicine and cannot be sold or supplied for human or veterinary consumption. The buyer is responsible for ensuring lawful, compliant handling under their own jurisdiction.
- Is Ipamorelin intended for human use?
- No. Ipamorelin supplied by Kovalabs is a research chemical for laboratory use only. It is not for human or veterinary use, is not a licensed medicine, and holds no marketing authorisation. No human or veterinary application is intended or implied, and it must not be administered to people or animals.
- What are the molecular identifiers for Ipamorelin?
- Ipamorelin has molecular formula C38H49N9O5, molecular weight 711.9 g/mol, CAS number 170851-70-4 and PubChem CID 9831659. Its peptide sequence is Aib-His-D-2-Nal-D-Phe-Lys-NH2. A known synonym is NNC 26-0161. These identifiers let researchers confirm the material against public chemical databases.
- Is all Ipamorelin the same?
- Not necessarily. Quality depends on synthesis and verification. Kovalabs releases each batch only after independent testing, with purity assessed by HPLC at 99% or greater and identity confirmed by HPLC retention-time matching (HPLC-RTM) against a reference standard for CAS 170851-70-4. A batch-specific Certificate of Analysis is provided, which is the difference between a characterised reference compound and unverified material.
- What purity is Kovalabs Ipamorelin?
- Kovalabs Ipamorelin is supplied at 99% or greater purity as assessed by HPLC, with identity confirmed by HPLC retention-time matching (HPLC-RTM) against a reference standard for the formula C38H49N9O5. The result for the specific lot is recorded on its Certificate of Analysis, published on our CoA page, so the figure can be verified per batch rather than taken on assertion.
- Is a Certificate of Analysis provided with Ipamorelin?
- Yes. Every batch ships with a batch-specific Certificate of Analysis reporting HPLC purity and identity confirmation. Current documents are published on the Kovalabs CoA page. The CoA is how the stated 99% HPLC purity and the molecular identity of each lot can be independently checked before research use.
- How is Ipamorelin supplied and reconstituted?
- Ipamorelin is supplied as a white to off-white lyophilised (freeze-dried) solid. For laboratory research it is reconstituted at the bench using a suitable research solvent such as bacteriostatic water. The vial mg strength is a product specification, not a usage instruction, and no guidance on administration to any human or animal is given or implied.
- How should Ipamorelin be stored?
- Store lyophilised Ipamorelin at -20C, kept dry and protected from light, where it is stable long term. Once reconstituted, hold the material at 2-8C and protect it from light. Correct cold, dark, dry storage preserves peptide integrity for laboratory research; these are handling conditions for a research reference compound only.
- How does Ipamorelin differ from CJC-1295?
- They are distinct molecules studied within the same GH-axis. Ipamorelin is a short GHS-R agonist pentapeptide acting at the ghrelin receptor, whereas CJC-1295 (in DAC and no-DAC forms) is a growth-hormone-releasing-hormone analogue acting on a different receptor. The frequent CJC-1295 and Ipamorelin search pairing reflects research interest in two different targets; this is an identity and pharmacology comparison only.
- How does Ipamorelin differ from sermorelin?
- Ipamorelin is a GHS-R (ghrelin receptor) agonist pentapeptide, while sermorelin is a growth-hormone-releasing-hormone analogue acting on the GHRH receptor; they are chemically and pharmacologically distinct molecules in the same research category. Both are supplied by Kovalabs as research-use-only reference compounds, not as medicines or substitutes for any licensed product.
- Is Ipamorelin a peptide or a steroid?
- Ipamorelin is a peptide, specifically a synthetic pentapeptide (five amino-acid residues, sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2). It is not a steroid. It is studied as a selective agonist of the growth-hormone secretagogue receptor and is supplied as a lyophilised research reference compound for laboratory use only.
- Can I buy Ipamorelin in the UK from Kovalabs?
- Yes. Kovalabs supplies Ipamorelin in the UK as a research chemical for laboratory use only, despatched from the UK with a batch-specific Certificate of Analysis. It is sold per vial as a research reference material. It is not sold for human or veterinary consumption and is not a licensed medicine; the buyer is responsible for compliant handling.
