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.

Applications of 4-HO-EPT

For forensic, analytical, or in vitro use only. Not for human consumption!

• Neurochemical research: Interaction with 5-HT2A receptors
• Structural pharmacological comparison study
• Binding studies and receptor profiling
• Cognitive modeling in laboratories
• Stability testing and crystallographic analysis

Advantages

• High purity (≥98%) suitable for reliable experiments
• Unique binding profile for research into serotonergic mechanisms
• Stable as fumarate – longer shelf life than the free base salt
• Lesser-known molecule , interesting for groundbreaking research

Disadvantages and Risks

• Limited scientific research available – effects largely anecdotal
• No approved medical use
• Risk of misuse or confusion with related substances
• Sensitive to oxidation when exposed to air and light
• Legal status unclear in some countries/regions

Recommended Research Use

• Dosage for in vitro simulations: 0.5 – 2 mg per reaction
• 溶剂： Ethanol or sterile aqueous solution, depending on the intended use
• 贮存： Cool (2-8°C), dry, light-free
• pH stability: Stable between pH 5.5 – 7.5

常见问题 (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 不是 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.

Important Warning

4-HO-EPT Fumarate is intended for scientific analysis only . Use outside of laboratory conditions can be life-threatening . Possession or use of this substance outside of authorized research may be punishable by law.
