4-Me-TMP
4-Me-TMP is a research chemical stimulant structurally related to methylphenidate with approximately one-third the potency. It was briefly available after UK bans on other phenidates in 2015 before being classified as a Temporary Class Drug. User reports describe functional, methylphenidate-like stimulation with limited recreational euphoria at low doses, though some euphoria emerges at higher doses. Cardiovascular effects include tachycardia and elevated blood pressure. Long-term safety profile is unknown.
