α-methyl Serotonin (maleate) is an agonist of serotonin (5-HT) receptors. It binds selectively to 5-HT1A, 5-HT1B, 5-HT1C, and 5-HT1D receptors over 5-HT1E receptors. It is also selective for 5-HT2B and 5-HT2C receptors over 5-HT2A receptors. α-methyl Serotonin potentiates motor neuron depolarizations induced by NMDA in the presence of the NMDA receptor antagonist memantine. It also increases dopamine release in a dose-dependent manner. α-methyl Serotonin increases systolic blood pressure and transiently increases heart rate.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
