    Ipamorelin Peptide: A Provider's Guide to Identity and Sourcing

    Short answer: Ipamorelin is a synthetic pentapeptide with the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2, molecular formula C38H49N9O5, and a molecular weight of about 711.9 g/mol (PubChem CID 9831659). It was first described by Raun and colleagues in the European Journal of Endocrinology in 1998 (Raun et al., 1998). Clinics receive the ipamorelin peptide as a lyophilized vial, and Biomed Peptides supplies it only to verified licensed providers.

    This guide sticks to what your team needs for purchasing and COA review: identity, supply format, how ipamorelin relates to the CJC-1295 No DAC listing in our catalog, and how provider access works.

    What is the ipamorelin peptide?

    Chemical identity

    PubChem lists the following for ipamorelin (PubChem CID 9831659):

    Attribute Value
    Name Ipamorelin
    Development code NNC 26-0161
    Sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2
    Length 5 residues, C-terminal amide
    Molecular formula C38H49N9O5
    Molecular weight ≈711.9 g/mol
    CAS (as listed) 170851-70-4

    Non-standard residues

    Three of ipamorelin's five residues aren't among the standard L-amino acids found in proteins:

    • Aib: α-aminoisobutyric acid
    • D-2-Nal: D-3-(2-naphthyl)alanine
    • D-Phe: D-phenylalanine

    Your supplier's COA should confirm identity by mass spectrometry, at about 712 Da for the free base. A simple amino-acid-composition check won't capture these residues, which is one more reason to ask for MS data.

    How ipamorelin is supplied to clinics

    Lyophilized vial format

    Ipamorelin comes freeze-dried in sealed vials. Lyophilized powder is much more stable than peptide in solution (Bachem). Our lyophilized peptides guide explains the format and the clinic reconstitution workflow.

    The Biomed Peptides lyophilized catalog lists Ipamorelin in 5 mg and 10 mg standalone vials.

    Storage and diluent

    • Store sealed, cold, dry, and away from light, following the label (Bachem).
    • Let a cold vial warm to room temperature before you open it.
    • Avoid repeated freeze-thaw cycles.
    • Use only the diluent named on the labeling. See our guide to bacteriostatic water for peptides.

    The lyophilized peptides storage guide covers each storage rule in detail.

    Ipamorelin and CJC-1295

    People who search for ipamorelin often search for CJC-1295 in the same session. They're different peptides, each with its own identity and documentation. The Biomed Peptides catalog lists CJC-1295 No DAC separately, in 10 mg and 20 mg vials. Treat each one as its own product with its own lot COA. A full explainer on CJC-1295 is coming in a future post.

    Ipamorelin peptide: how providers buy

    Searches like "ipamorelin peptide buy" mostly lead to consumer sites. Biomed Peptides supplies physician-use product only to licensed healthcare providers and GPOs, and we don't sell to patients or consumers. Here's how access works:

    1. Submit the provider application.
    2. Our team verifies your credentials, usually within 24–48 hours.
    3. Approved accounts can see wholesale pricing, the full catalog, and quality documentation.
    4. Order for office use or patient-specific fulfillment, with shipping to all 50 states.

    Prescribing authority depends on the license and the state. See who can prescribe peptides for the general framework, and confirm your state's rules. For background on sourcing channels, see what a 503A pharmacy is.

    Documentation to request for ipamorelin

    • A lot-specific COA: MS identity (≈712 Da), HPLC purity, and peptide content
    • An endotoxin report
    • Labeled storage conditions and expiration

    Our wholesale peptide supplier guide explains how to compare suppliers on documentation.

    Licensed practices can apply for provider access to view ipamorelin and CJC-1295 No DAC pricing and lot documentation, or browse the lyophilized catalog.

    FAQ

    What is the ipamorelin peptide?

    Ipamorelin is a synthetic pentapeptide, Aib-His-D-2-Nal-D-Phe-Lys-NH2 (C38H49N9O5, about 711.9 g/mol), first described in 1998.

    How many amino acids are in ipamorelin?

    Five. Three of them (Aib, D-2-naphthylalanine, and D-phenylalanine) are non-standard residues.

    Is ipamorelin the same as CJC-1295?

    No. They're separate peptides. Biomed Peptides lists Ipamorelin and CJC-1295 No DAC as separate catalog items, each with its own documentation.

    Where can a practice buy ipamorelin peptide?

    From a provider-only supplier that verifies licensure. Biomed Peptides supplies ipamorelin to approved providers through /apply.

    How is ipamorelin supplied?

    As a lyophilized powder in sealed vials. Our catalog lists 5 mg and 10 mg vials.
