MT-1 (Melanotan I) is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH) studied for its interaction with melanocortin receptors and its role in pigmentation and melanogenesis pathways.
Melanocortin Research
Studied for its interaction with melanocortin receptors and associated cellular signaling pathways.
Melanogenesis Pathways
Investigated in experimental models examining melanin production and pigmentation mechanisms.
α-MSH Analog
Researched as a synthetic analog of the naturally occurring alpha-melanocyte-stimulating hormone.
Pigmentation Research
Used in laboratory research exploring biological pathways associated with pigmentation and melanocyte activity.
What Melanotan I is
Melanotan I is a linear analogue of alpha-MSH, and the contrast with Melanotan II is structural before it is pharmacological: one is linear, the other cyclic, and that difference in backbone constraint is what drives their different receptor behaviour.
Within the melanocortin family, selectivity is the axis that matters. The subtypes sit in different systems, so how broadly a ligand engages them determines how many systems it touches.
Handling and reconstitution
Standard lyophilised peptide handling applies. Keep the sealed vial cold and dark until it is used. Reconstitute by running bacteriostatic water slowly down the inside wall of the vial rather than firing it onto the powder cake, and let it dissolve without shaking — swirl gently if it needs help.
The concentration you end up with is set by how much water you add, not by the vial size. Our reconstitution calculator turns vial mass and water volume into a concentration and a syringe reading.
Storage
Sealed and lyophilised: refrigerated, protected from light. In solution: refrigerated, and treat time at room temperature as a cost. Avoid repeated freeze-thaw once reconstituted.
What ships, and what is on the certificate
The vial ships sealed as it was filled. Every compound in the catalogue is tested by an outside laboratory — Vanguard Laboratory in Olympia, Washington — and the certificate is published in full rather than summarised.
The certificate reports chromatographic purity by HPLC with the chromatogram visible, the measured quantity in milligrams, and an endotoxin result by LAL. Measured quantity usually reads slightly above the label, which is normal: fills are targeted high so every vial meets its stated content.
Frequently asked questions
What is the difference between Melanotan I and II?
Melanotan I is linear; Melanotan II is cyclic and engages melanocortin receptor subtypes more broadly. The backbone difference drives the selectivity difference.
How should it be reconstituted?
Add bacteriostatic water slowly down the inside wall of the vial, then let it dissolve without shaking. The reconstitution calculator will convert vial mass and water volume into a concentration and a syringe reading.
Does it come with a certificate of analysis?
Yes. Every compound is tested by an independent laboratory and the full certificate, chromatogram included, is published on the site rather than summarised.
Is this a medicine?
No. It is sold for in-vitro laboratory research use only. It is not a drug, supplement or cosmetic, and is not for human or veterinary use.
