Melanotan I is a linear synthetic analog of α-melanocyte-stimulating hormone (α-MSH). Elyria Bio supplies it as a lyophilized 10 mg reference material, characterized to 99.1% by reversed-phase HPLC, for in-vitro laboratory research only.
Molecular formula C78H111N21O19 · molecular weight 1646.85 g/mol · CAS 75921-69-6. Every lot is held to a ≥99% HPLC purity floor and ships with a third-party certificate of analysis.
Overview
As a characterized reference material, Melanotan I is used to standardize in-vitro assays in melanocortin (MC1R) pigmentation-pathway research. Descriptors reference documented in-vitro and pre-clinical context only and make no therapeutic claim.
Elyria Bio supplies Melanotan I as a lyophilized acetate salt, characterized by reversed-phase HPLC to 99.1% purity and confirmed by ESI mass spectrometry against its theoretical mass. Every lot ships with a third-party certificate of analysis documenting purity, identity, and endotoxin load (< 0.5 EU/mg), and is fully traceable to its matching COA. Pair it with GLP-2 or GLP-3, or browse the full metabolic collection for related reference standards.

Specifications
Representative release specification. Each shipped lot is documented on its own signed third-party certificate of analysis.
Certificate of analysis
Every shipped vial resolves to a signed third-party COA. Preview the representative certificate for the current lot, download it as a PDF, or verify any printed lot number in batch lookup.
Certificate of Analysis
Lot On fileDocumentation you can verify
The COA is produced by an independent United States laboratory — not in-house — and reports RP-HPLC purity and mass-spec identity for this material's specific lot. The printed lot code on your vial resolves to this exact document and its assay date.
Storage & handling
Lyophilized Melanotan I is stable long-term when kept cold and dry. Handle under standard laboratory aseptic technique.
Sealed and desiccated, protected from light. Stable approximately 1–2 years from the assay date printed on the COA.
After reconstitution with bacteriostatic water, refrigerate and use within the stability window appropriate for your study. Avoid repeated freeze-thaw cycles.
Divide into single-use aliquots before freezing to preserve integrity and minimize handling of the stock solution.
Reconstitute with sterile or bacteriostatic water for multi-draw laboratory preparations. Reconstitution volumes and concentrations are determined by the researcher for the assay at hand; Elyria Bio does not provide dosing guidance, as all materials are supplied for in-vitro research use only.

Frequently asked questions
What is Melanotan I?
Melanotan I is a linear synthetic analog of α-melanocyte-stimulating hormone (α-MSH). Elyria Bio supplies it strictly as a lyophilized powder in-vitro laboratory reference material for qualified research professionals.
What is Melanotan I used for in research?
In laboratory settings Melanotan I is used as a reference standard in melanocortin (MC1R) pigmentation-pathway assays and related in-vitro studies. It is not a drug, supplement, or food and is not for human or veterinary use.
How pure is Elyria Bio's Melanotan I?
Every lot is held to a ≥99% reversed-phase HPLC purity floor before release; the current lot is characterized at 99.1%. Molecular identity is confirmed by ESI mass spectrometry against the expected mass, and endotoxin is reported at < 0.5 EU/mg.
Does Melanotan I ship with a certificate of analysis?
Yes. Each lot ships with a signed third-party certificate of analysis produced by an independent United States laboratory, reporting HPLC purity and mass-spec identity. Every vial's printed lot number resolves to its own COA and assay date, which you can confirm through batch lookup.
How should Melanotan I be stored?
Store the lyophilized powder sealed and desiccated at −20°C, protected from light, where it is stable for 1–2 years. Once reconstituted with bacteriostatic water, refrigerate at 2–8°C and use within the stability window appropriate for the study; avoid repeated freeze-thaw cycles.
Is there bulk pricing for Melanotan I?
Yes. Multi-vial volume pricing applies automatically in the cart: 3 or more vials receive 15% off and 5 or more vials receive 25% off. Orders over $150 ship free within the United States, with free express shipping over $250.
