Psychedelic Research Chemicals or RC Chems are new synthetic substances which are structurally similar to the original drug, while being functional analogs. Data on their effects limited due as they’re fairly new and do not have a lot of human consumption history.

Psychedelics are substances (natural or laboratory made) which cause profound changes in a one’s perceptions of reality. While under the influence of hallucinogens, users might hallcuniate visually and auditorily.

Disclaimer: Psychedelic drugs offer some of the most powerful and intense psychological experiences. Additionally these substances are illegal in many places. We understand that even though these substances are illegal, their use occurs frequently. We do not condone breaking of the law. By providing accurate information about these substances, we encourage the user to make responsible decisions and practice harm reduction.

A relatively uncommon psychedelic phenethylamine and possible MAOI. Long lasting, an possesses an unpredictable dosage curve. Questionable safety in combination with most things.


2C-T-7 was first synthesized by Alexander Shulgin and documented in his book PiHKAL ("Phenethylamines I Have Known and Loved"). It is a member of the 2C-x family of psychedelic phenethylamines, all of which were derived from the systematic modification of the mescaline molecule. In contrast to other members of the 2C-x family, 2C-T-7 has gained a reputation of being an unpredictable, dose-sensitive psychedelic capable of producing strong visual effects and an intense body load, which can manifest as a dangerous delirium in extreme cases.

Many reports indicate that the physical effects are too severe for inexperienced users or those with pre-existing medical conditions. This particular compound is part of the so-called “magical half-dozen” which refers to Shulgin’s self-rated most important phenethylamine compounds, all of which – with the exception of mescaline – he designed, synthesized and tested on himself. They can be found within the first book of PiHKAL, and are as follows: Mescaline, DOM, 2C-B, 2C-E, 2C-T-2 and 2C-T-7.


2C-T-7 is also substituted at R4 with a propyl thioether group. 2C-T-7 is analogous to 2C-T-2; the two differ by the length of the alkane chain in their thioether functional group.
