Buy Melanotan II for Research

Melanotan II 10mg ships from stock we hold in the United States. Each vial contains 10mg of lyophilized Melanotan II, sealed and ready for reconstitution at the bench. A single vial is $39. Bundle pricing lowers the per vial price automatically at two, three and five units, with no code to enter. Order before 4PM ET and it leaves the same day.

What researchers look for in a Melanotan II supplier

Melanotan II is not hard to find. Consistent supply, an honest stock number and a checkout that works on the first attempt are harder. Here is what we hold ourselves to on this compound, and what any supplier should be held to before a purchase order goes out to them.

Real stock, on a shelf in the United States. The count on this page is live, not a promise. Melanotan II 10mg is in stock now at 8 vials. Inventory sits in a US facility, so an order does not wait on an overseas restock before it moves.

One published price, visible before checkout. The vial is $39. Every bundle tier is printed on this page, so the cost of two, three or five vials is known before anything reaches a cart. No account gate, no quote request, no minimum order.

Purity held to a fixed standard. Every lot of Melanotan II we list meets 97% purity or higher, and material below that standard does not go on the site. The specification is stated in plain figures, with molecular weight and CAS number.

Dispatch measured in hours, not days. Orders placed before 4PM ET leave the same day, seven days a week, weekends included. Tracking is emailed the day the parcel goes out. A Sunday order placed at 3PM ET moves on Sunday, which is the part most suppliers quietly exclude.

What Melanotan II is, in research terms

Melanotan II is a synthetic cyclic heptapeptide analog of alpha-melanocyte stimulating hormone, CAS 121062-08-6. The sequence is Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2, the molecular formula is C50H69N15O9 and the molecular weight is 1,024.18 Da. A lactam bridge between the aspartate and lysine side chains closes the macrocycle and holds the His-D-Phe-Arg-Trp pharmacophore in a fixed conformation. The acetylated N terminus, the amidated C terminus and the D-phenylalanine substitution together separate it from the native linear hormone.

The published preclinical literature treats the peptide as a broad melanocortin receptor agonist, active at MC1R, MC3R, MC4R and MC5R, with cyclic AMP accumulation as the standard functional readout. That lack of subtype selectivity is what makes it useful as a reference tool. Set against a subtype selective agonist, or against an antagonist such as SHU9119, it lets an investigator work out which receptor arm carries a signal. The constrained ring also resists enzymatic breakdown far better than linear alpha-MSH.

The recurring model systems are transfected HEK293 and COS lines expressing single melanocortin receptor subtypes, murine B16 melanoma cells and primary melanocyte cultures for pigment biology, and rodent model systems for central MC4R circuit work. Assay classes include radioligand binding, cyclic AMP accumulation, reporter gene readouts, tyrosinase and melanin quantification, quantitative PCR and Western blot. For a neighboring melanocortin agonist and how the same receptor family is approached from another angle, see PT-141 (Bremelanotide): Melanocortin Receptor Research.

Reconstitution arithmetic, storage temperatures and handling notes for this compound are collected in free research guide for Melanotan II, free to download with no account required. It carries the concentration table for 1, 2, 3 and 5 mL of diluent along with the assay classes above in more depth.

Melanotan II is the non selective reference that subtype selective agonists and antagonists such as SHU9119 get scored against, so a real receptor panel means the same peptide added to MC1R, MC3R, MC4R and MC5R lines on the same day, with pigment work running beside it. One vial rarely covers that. The cart itself takes 5% off two, 10% off three and 15% off five. Five vials put the order past $150, where US shipping is free, and the set ships as one handling batch.

US stock, international shipping and same-day dispatch

Orders placed before 4PM ET are dispatched the same day, seven days a week. Weekends are not an exception here. Tracking is emailed the same day the parcel leaves, so the compound is confirmed moving before the working day ends. Because stock is held in the United States, nothing waits on an overseas warehouse or a customs clearance queue first.

Standard Shipping inside the United States is $12 and arrives in 2 to 5 business days, free on orders over $150. Expedited 2-3 Day is $39 and Overnight is $95. Standard International is $40 flat and arrives in 10 to 20 business days, free on orders of $500 and above. Express International is $100 flat and arrives in 5 to 10 business days.

Storage and handling

Keep the sealed lyophilized vial at minus 20C for long term storage, or at 2 to 8C for short term holding, shielded from light and brought to room temperature before the seal is broken. Once reconstituted, hold the vial at 2 to 8C, upright and out of the light, and treat it as a short lived working stock. Full temperature guidance sits in storage and handling page, and reconstitution calculator will work out the concentration for any diluent volume you choose.

Checkout, payment and support

Checkout takes Visa and Mastercard directly on the site. The card is processed in one pass on our own pages, with no redirect to a third party wallet and no invoice to wait on. You enter the card, the order confirms, and the dispatch clock starts.

Support replies within one business day. If a parcel arrives damaged or the wrong item is inside, email the order number with a photograph and we will replace it or refund it. There is no restocking argument to have first.

Frequently asked questions

What is Melanotan II?

Melanotan II is a synthetic cyclic heptapeptide analog of alpha-melanocyte stimulating hormone, CAS 121062-08-6, with the molecular formula C50H69N15O9 and a molecular weight of 1,024.18 Da. Its sequence is Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2, closed by a lactam bridge between the aspartate and lysine side chains. Published preclinical work describes it as a broad agonist at melanocortin receptors MC1R through MC5R and uses it as a reference agonist in receptor binding and cyclic AMP assays.

Why buy Melanotan II from Core Research Peptides?

Stock is held in the United States and the count on the page is live, currently 8 vials. The price is published at $39 a vial with every bundle tier printed in full, so nothing is quoted on request. Orders placed before 4PM ET are dispatched the same day, seven days a week, with tracking emailed the same day. Email support answers inside one business day, and card payment finishes on our own checkout in a single pass with no redirect.

What purity is your Melanotan II?

Every lot we list is held to 97% purity or higher, and material below that standard is not listed for sale. The vial contains 10mg of lyophilized Melanotan II, with the molecular weight and CAS number stated on the product page so the specification can be checked against your own records before you order.

How fast do you ship Melanotan II, and what does shipping cost?

Orders placed before 4PM ET are dispatched the same day, seven days a week, and tracking is emailed the same day the parcel leaves. Inside the United States, Standard Shipping is $12 and arrives in 2 to 5 business days, free on orders over $150. Expedited 2-3 Day is $39. Overnight is $95. Inventory sits in a US facility, so dispatch never waits on a restock.

Do you ship Melanotan II internationally?

Yes. Standard International is a $40 flat rate with a 10 to 20 business day transit, free on orders of $500 and above. Express International is a $100 flat rate with a 5 to 10 business day transit. International orders leave on the same schedule as domestic ones, same day before 4PM ET, seven days a week, with tracking emailed the day the parcel goes out.

Do you offer bundle pricing on Melanotan II?

Yes. Two vials are $37 each, three are $35 each and five are $33 each, which is 5%, 10% and 15% off the single vial price of $39, floored to whole dollars. The discount is applied automatically in the cart with no code to enter, and the cart uses either bundle pricing or a coupon code, never both. Five vials at $165 also clears the $150 free shipping threshold.

How should Melanotan II be stored?

The sealed lyophilized vial keeps at minus 20C for long term storage, or at 2 to 8C for short term holding. Protect it from light and let it reach room temperature before the seal is broken. Once reconstituted, keep the vial at 2 to 8C, upright and out of the light, and treat it as a short lived working stock rather than a long term reserve.
