What is 4-AcO-MPT Fumarate?

4-AcO-MPT is a psychedelic tryptamine and an ester form of 4-HO-MPT. It is structurally related to both psilocin (4-HO-DMT) and other 4-substituted tryptamines, and is being investigated for its potential agonist activity at 5-HT2A receptors . As a fumarate salt , it is more suitable for laboratory applications than the free base due to its greater stability and solubility.

⚠️ For scientific and analytical use only. Not intended for human consumption.

FAQ – Frequently Asked Questions

❓What is 4-AcO-MPT used for?

For basic neuropharmacological research , receptor analysis, and experiments with serotonergic pathways.

❓What is the difference with 4-HO-MPT?

4-AcO-MPT is the acetoxy ester of 4-HO-MPT, meaning it may function as a prodrug in biological systems, although this has only been theoretically established.

❓Is this substance legal in the Netherlands or Belgium?

There’s no explicit prohibition, but due to analogue legislation , it may still fall under the Opium Act. Always consult a legal specialist or agency.

❓Can I use this product personally?

Absolutely not. This product is intended solely for professional, controlled laboratory use .

❓How long does this substance remain stable?

When stored correctly: at least 24 months without significant decrease in purity.
