Centafarm ken ik niet...Same! Ik heb 54 mg (langwerkend) en had altijd Mylan, maar nu opeens centrafarm... Gelukkig heb ik nog wat Mylan over maar ben een beetje bang voor centrafarm haha. Heb jij veel bijwerkingen hiervan?
En welke variant zou dan gelijk staan aan de 10 mgEr bestaan ook research varianten, heb je die al eens geprobeerd?
Jammer genoeg schijnt de 4F-MPH van tegenwoordig echt ruk te zijn.
Het is geen verantwoorde vervanger van de officiële medicatie, maar ....
Geen. Dit is echt waardeloos advies. Je kan RC's niet als medicijn gebruiken.En welke variant zou dan gelijk staan aan de 10 mg
Opa, vertelt u alstublieft nog eens dat verhaal waarom u vroeger bent weggegaan uit uw woonplaats en hier bent komen wonen!Verhuizen
Wat is er mis mee en sinds wanneer is er wat mis mee?Jammer genoeg schijnt de 4F-MPH van tegenwoordig echt ruk te zijn.
Vragen naar verkooppunten is niet toegestaan op straffe van een permanente ban. Die krijgt u bij deze. Ajuu!Centafarm ken ik niet...
Ik heb de kort werkende van Mylan.
Waar haal jij die langwerkende? Woon je in Groningen? De meeste apotheken hebben dezelfde leverancier helaas hier...
En welke variant zou dan gelijk staan aan de 10 mg

This study describes the analytical characterization of two powdered samples and a set of tablets of 4-fluoromethylphenidate that were obtained from the same vendor based in the United Kingdom in 2015. The study was triggered following the receipt of two powdered 4F-MPH samples from an online retailer. Various chromatographic, spectroscopic and mass spectrometric analysis methods were employed, followed by x-ray crystal structure analysis. One of the vendor samples was found to contain (±)-threo-4F-MPH, which was consistent with the expected racemate based on the current knowledge of the biological activity of (±)-threo-MPH. Unexpectedly, the analysis of the second sample revealed that it consisted of a mixture of (±)-threo and (±)-erythro-4F-MPH. This suggested that the two powdered vendor products might have originated from different batches. The two racemates were isolated from the mixture, purified, and converted to HCl salts prior to full analytical characterization. In addition, 4F-MPH tablets were also obtained from the same vendor and analysed for the presence of the (±)-threo and/or (±)-erythro form.
It was hypothesized that the distinct forms of 4F-MPH encountered in these products would result in different pharmacological properties similar to what has been reported for MPH, thus, potentially resulting in different effects in consumers. For this reason, the ability of the test drugs to inhibit uptake of [3H]dopamine, [3H]norepinephrine and [3H]serotonin was investigated using synaptosomal preparations from rat brain. The isolated diastereomeric racemates (±)-threo and (±)-erythro-4F-MPH, the (±)-threo/(±)-erythro mixture, and MPH were included to study the effects at dopamine transporters (DAT), norepinephrine transporters (NET) and serotonin transporters (SERT), respectively.
The stuff on the market now is significantly worse than what was available 5 years ago. I was addicted to stimulants years ago. Tried every drug out there. Since then I’ve been diagnosed with ADHD and prescribed almost every pharmaceutical medication. The 4f from 2016-2018 is still my favorite drug of all time.
