What is 4-HO-EPT Fumarate?

4-HO-EPT is a rare tryptamine derivative belonging to the class of serotonergic psychedelics. It is chemically related to psilocybin and 4-HO-MET, but has unique pharmacological properties due to the ethyl and propyl groups on the amine nitrogen. In its fumarate form, this substance is more soluble and chemically more stable for long-term storage.

Frequently Asked Questions (FAQ)

Is 4-HO-EPT legal in the Netherlands or Belgium?
Its legal status is not explicitly defined. It may fall under the analogues legislation or the Medicines Act, depending on interpretation. Use only for authorized research.

What’s the difference between 4-HO-EPT and psilocybin?
Both are tryptamines, but 4-HO-EPT has a synthetic ethyl-propyl structure instead of a phosphate group like psilocybin, resulting in differences in pharmacokinetics.

Can this substance be used orally?
No. 4-HO-EPT is intended for laboratory testing only and not for human consumption.

How do I store this product optimally?
In a dark, dry place at temperatures between 2°C and 8°C. Avoid contact with air.

Is the product stabilized as a fumarate?
Yes, the fumarate version increases stability compared to the free base salt, especially during long-term storage.
