Which format?
| Nasal spray | Vial | |
|---|---|---|
| Concentration | 1 mg per mL (10 mg in 10 mL); each 0.1 mL of solution contains 100 micrograms | — |
| How supplied | Ready-made solution in a 10 mL spray bottle | — |
| Needs mixing? | No. The lyophilised 10 mg vial needs reconstitution; the spray does not | Yes, with BAC water |
| Storage | 2–8 °C, upright, away from light; do not freeze | −20 °C dry; 2–8 °C mixed |
Storage and handling
Keep the spray solution in a refrigerator at 2–8 °C, capped and away from light. A peptide in solution breaks down faster than dry powder, so for long storage the lyophilised vial kept at −20 °C is the more stable choice.
Studies that used the intranasal route
The studies in our records gave MT-II into the brain, the spinal fluid, a vein or the penis (rats), by osmotic minipump (rats) or by subcutaneous injection (human case report). None used the nose, so no intranasal evidence rows are shown.
Nasal spray FAQ
Is there research on Melanotan II nasal spray?
Not in the records behind this page. The Melanotan II studies we hold used routes into the brain, spinal fluid, a vein or the penis in rats, or osmotic minipumps. The human case report involved subcutaneous injection. We do not list intranasal studies because we have none to cite.
What is the concentration of the Melanotan II nasal spray?
The spray holds 10 mg of Melanotan II in 10 mL of solution, which is 1 mg per mL. Each 0.1 mL therefore contains 100 micrograms. This is the concentration of the solution, not a dose.
Nasal spray or vial: which suits a lab better?
The vial suits work that needs a chosen concentration or long storage, because the dry powder keeps best at −20 °C and is made up only when needed. The spray is already in solution at 1 mg per mL, so there is no reconstitution, but it has to be refrigerated and has a shorter shelf life.
How long does the nasal spray last once opened?
Keep it at 2–8 °C and use it within about 28 days of opening, in line with what is generally reported for peptides in solution. Discard it if it turns cloudy or changes colour.
