Chemical identity

What Ipamorelin is

Ipamorelin (INN; research code NNC 26-0161) is a synthetic pentapeptide amide with the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2, i.e. 2-methylalanyl-L-histidyl-3-(2-naphthyl)-D-alanyl-D-phenylalanyl-L-lysinamide. It contains two non-proteinogenic residues, alpha-aminoisobutyric acid (Aib) at the N-terminus and 3-(2-naphthyl)-D-alanine (D-2-Nal) at position 3, together with a D-phenylalanine at position 4 and a C-terminal primary amide. The free base has the molecular formula C38H49N9O5 and a molecular weight of 711.85 g/mol (PubChem CID 9831659, CAS 170851-70-4, UNII Y9M3S784Z6), matching the Pepta Labs listing. The compound is commonly isolated as ipamorelin acetate. Pepta Labs supplies ipamorelin as a lyophilized powder in sealed glass vials (5 mg and 10 mg quantities) with reported RP-HPLC purity and mass-spectrometric identity. Store at 2-8 C on arrival or at -20 C for long-term storage, away from light and moisture. Laboratory research use only.

Structural class: synthetic pentapeptide amide containing alpha-aminoisobutyric acid (Aib), 3-(2-naphthyl)-D-alanine and D-phenylalanine
Residues: 5 amino acids
Salt form: typically supplied as acetate salt (ipamorelin acetate) or trifluoroacetate salt
PubChem CID: 9831659
UNII: Y9M3S784Z6

Questions

Ipamorelin 5mg — common questions

What is the difference between ipamorelin 5mg and 10mg?

Only the supplier-stated quantity in the vial and the price. Both listings are the same compound, CAS 170851-70-4, as lyophilized powder in a sealed glass vial, with RP-HPLC purity and mass-spectrometry identity reported. This page is the 5 mg vial; Ipamorelin 10mg is the larger vial.

What is in an ipamorelin 5mg vial?

5 mg of ipamorelin (supplier-stated quantity) as a dry lyophilized powder in a sealed glass vial, with no liquid added. The vial label names the compound, the quantity and the research-use designation and carries no lot or batch number. Net peptide content is not reported per listing, so the 5 mg figure is the stated fill, not a measured peptide mass.

Is ipamorelin 5mg supplied as ipamorelin acetate?

Ipamorelin is typically supplied as the acetate salt (ipamorelin acetate) or the trifluoroacetate salt. The powder mass therefore includes the counter-ion as well as the peptide. The listing does not state a per-vial salt form; email support@peptalabs.com if your work depends on it.

Can I see the ipamorelin 5mg analytical report before I order?

Yes. Request it on this page or email support@peptalabs.com with the compound name and size, and it is sent by email. The report covers the sampled production run and gives purity as RP-HPLC area-% and identity by mass spectrometry. It is not a lot-specific certificate, and sterility or endotoxin testing is not claimed.

How should ipamorelin 5mg be stored after delivery?

Refrigerate the sealed vial at 2-8 °C on arrival, or hold it at -20 °C for long-term storage, protected from light and moisture. The dry powder travels at ambient temperature and needs no cold pack in transit.

Where can I read more about ipamorelin sizes and identity data?

The Learn guide on ipamorelin sets out the sequence, the salt forms and both Pepta Labs listings side by side. For reading the report itself, see How to Read and Verify a Peptide Certificate of Analysis (COA).

What does Ipamorelin 5mg cost?

Ipamorelin 5mg starts at $36.99 per vial. 3-vial packs are 7% off and 5-vial packs are 14% off. US shipping is free with no minimum.

What payment methods are accepted?

Pepta Labs accepts Cash App, Venmo, Zelle, Bitcoin and Ethereum (5% crypto discount). Payment instructions are emailed as soon as you place your order.

Is this for human or animal use?

No. Ipamorelin 5mg is offered solely for laboratory research and is not for human or animal use, consumption, administration, diagnosis or treatment. Buyers certify this at checkout.

What does the CAS number 170851-70-4 identify?

It is the registry number for the free base of ipamorelin, Aib-His-D-2-Nal-D-Phe-Lys-NH2 (C38H49N9O5, 711.85 g/mol), matching PubChem CID 9831659 and UNII Y9M3S784Z6. The acetate salt is the same peptide with an acetate counter-ion.

Which residues in ipamorelin are non-standard?

Aib (alpha-aminoisobutyric acid, 2-methylalanine) at position 1, 3-(2-naphthyl)-D-alanine at position 3 and D-phenylalanine at position 4 are not among the 20 standard L-amino acids; only histidine and lysine are standard. The C-terminus is a primary amide.

What ions are expected in the mass spectrum of ipamorelin?

For C38H49N9O5 the monoisotopic mass is 711.39 Da, so ESI-MS typically shows [M+H]+ near m/z 712.4 and [M+2H]2+ near m/z 356.7. The analytical report lists the observed mass together with RP-HPLC purity.
