4F-MPH, also known as 4-fluoromethylphenidate, is a synthetic compound that belongs to the class of substituted phenethylamines. It is a stimulant drug that acts as a potent reuptake inhibitor of dopamine and norepinephrine neurotransmitters in the brain, which leads to increased alertness, attention, and focus. The molecular formula of 4F-MPH is C14H18FNO2, and it has a molecular weight of 251.3 g/mol. It is available in the form of white crystalline powder and can be taken orally, intranasally, or intravenously. 4F-MPH is commonly used as a research chemical and is not approved for medical use. It has been found to have a longer duration of action and higher potency compared to other stimulant drugs such as methylphenidate. However, it also has a higher risk of adverse effects such as anxiety, insomnia, and cardiovascular issues. Overall, 4F-MPH is a potent and potentially dangerous compound that should only be used by trained researchers in a controlled setting with appropriate safety measures in place.

4F-MPH (4-Fluoromethylphenidate) is a synthetic stimulant compound of the phenidate class, and it is also known as 4F-MPH, 4F-methylphenidate, or 4F-MPH. This research chemical is structurally related to methylphenidate, which is a widely used prescription medication for the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy.

4F-MPH is a potent central nervous system stimulant that works by increasing the levels of dopamine and norepinephrine in the brain. It has a longer duration of action and a stronger potency than methylphenidate, which makes it a popular research chemical among scientists and researchers.

4F-MPH is usually sold in powder or crystal form and can be consumed orally, nasally, or intravenously. The onset of action is typically within 15-30 minutes of ingestion, and the peak effects last for 3-6 hours, depending on the dose and route of administration. The effects of 4F-MPH are dose-dependent, with low doses producing mild stimulant effects, and high doses producing intense euphoria, increased energy, and heightened focus.

Due to its high potency, 4F-MPH should be used with caution and only by experienced researchers who are familiar with the proper handling and dosing of research chemicals. It is important to start with a low dose and gradually increase the dose as needed, while carefully monitoring the effects on the subject.

Like all research chemicals, the long-term effects of 4F-MPH are not well understood, and more research is needed to determine its safety and potential risks. However, anecdotal reports suggest that regular use of high doses of 4F-MPH may lead to tolerance, dependence, and addiction.

In conclusion, 4F-MPH is a potent and highly effective research chemical that has gained popularity among scientists and researchers. However, it should be used with caution and only by experienced researchers who are familiar with the proper handling and dosing of research chemicals. Researchers should also follow the recommended safety precautions and guidelines to ensure their own safety and the safety of their subjects.

    Ich habe 1 gramm 4 F-MPH EU gekauft, das nach meiner Forschung als gut getestet wurde, die Lieferung dauerte etwas über eine Woche, mit Feiertagen dazwischen. Das Gewicht war auch genau. Ich bin mit diesem Verkäufer sehr zufrieden. Kann diesen Verkäufer durchaus Empfehlen
