2C-T-7: A Mixed Bag of Psychedelic Tricks

Justin Cooke Last Updated: August 23, 2021

2C-T-7 is a psychedelic empathogen created by Alexander Shulgin. There’s currently no formal research available for this chemical, but it’s been circulating around the research chemical market for a few decades and has garnered a bit of a reputation for itself.

This compound is equally loved and hated. Its effects are unpredictable. Some users report 2C-T-7 as one of the best psychedelics of all time.

With that said, opinions on this substance are split. Some users share the opposite sentiment — reporting nightmarish experiences, delirium-like hallucinations, and intensely uncomfortable body load.

Here, we’ll cover everything we know about 2C-T-7 so far.

What is 2C-T-7?

2C-T-7 stands for  2,5-Dimethoxy-4-propylthiophenethylamine. It’s a member of the 2C-X family of drugs — making it closely related to 2C-B, 2C-C, 2C-D, 2C-E, 2C-I, 2C-P, and others.

Alexander Shulgin discovered most of the members of this group while he was systematically attaching different functional groups to mescaline and then testing their effects.

2C-T-7 is in the 2C-T-X subfamily, for which there are about 25 members. Each compound in this family is numbered according to when they were discovered — starting with 2C-T, 2C-T-2, and so on. Shulgin discovered the 2C-T-X subfamily while working in collaboration with another infamous psychedelic chemist, Dr. David E. Nichols. Nichols is most famous for his discovery of lysergamide derivatives like AL-LAD, LSZ, ETH-LAD, and others.

Only about half of the members of the 2C-T-X subfamily are psychoactive. Out of the whole group, Shulgin lists 2C-T-7 as well as 2C-T-2 at the top in terms of their effects. In fact, 2C-T-7 is one of Shulgin’s “magic half dozen” — a term he uses to refer to his favorite creations over the years.

  11. 🐽 I’m aware that snorting 2C-T-7 could result in serious injury or death

What’s The Dose of 2C-T-7?

The standard dose of 2C-T-7 is between 10 and 30 mg. However, the effects of this drug at the 10 mg mark, compared to the 30 mg mark, can be exceptionally different. It’s hard to predict how each dose will feel from one person to the next.

It’s wise to start on the low-end of the dose with this compound and only increase the dose in subsequent experiences.

Dosage Breakdown for 2C-T-7

  1. Threshold Dose — 3 mg
  2. Standard Psychoactive Dose — 10–30 mg
  3. Heavy Dose — Not recommended

What Does 2C-T-7 Feel Like?

The effects of 2C-T-7 are highly unpredictable; some users experience profound effects at 10 mg, others take 20 or 30 mg and report mild effects.

The sentiment of the experience can vary a lot as well. Many trip reports on 2C-T-7 are positive. Users report feelings of connectedness, intense visuals, profound personal insights, projection, and euphoria. Some of the common names for this drug are “Blue Mystic” or “Beautiful” because of the intensity of the visual component. It isn’t hard to find users on Reddit who claim 2C-T-7 as one of their favorite 2C-X drugs. Even Alexander Shulgin himself lists 2C-T-7 as one of the best phenethylamine psychedelics of all time.

Other trip reports have the exact opposite sentiment. These trip reports resemble something more akin to a datura trip than a 2C-X psychedelic.

Key features of 2C-T-7 include:

  • Enhanced colors
  • Flowing, merging, & shifting visuals
  • Tracers & after images
  • Enhanced feelings of connection
  • Strong body load

Factors That Increase the Chances of Negative Experiences With 2C-T-7

There are some patterns in the trip reports available for this substance that give us a clue as to what could be the reason why there’s so much polarity in the sentiment of the psychedelic experience with this compound.

High Doses Are More Likely to Produce a Negative Experience

First, this drug is very dose-dependent. Even with a small increase in dose, users can go from having a pleasant experience to being overwhelmed and negative. This substance has intense visuals and maintains near-sober headspace, but isn’t as intense as many other psychedelics.

People who want to go deeper and take more, but the experience transitions into something much different at the higher doses. Body load becomes unbearable, hallucinations spill over into delirium, and the sentiment of the experience turns dark and malicious.

If you want a deeper psychedelic experience, don’t increase the dose further — this isn’t an appropriate psychedelic for “heroic” doses.

Snorting or Mixing 2C-T-7 May Result in Injury

Second, it appears that people who snort this substance are significantly more likely to have a negative experience. After analyzing dozens of negative trip reports, one of the most common overlaps is that the user either snorted 2C-T-7 or took it with other substances.

Ultimately, this drug is what it is. Common advice for this substance is to start with a low dose (10 mg) and see how that feels before taking more. Never exceed 30 mg, never snort it, and don’t mix 2C-T-7 with other substances.

How Long Does 2C-T-7 Last?

2C-T-7 is one of the longer-lasting psychedelics. On average, it takes about 2 hours for the effects to kick in; peak occurs around the 3-hour mark and lasts between 5–6 hours before tapering off over the course of another 4–6 hours.

The entire experience lasts between 8 and 15 hours in total.

How Strong is 2C-T-7 Compared To Other Psychedelics?

2C-T-7 is most similar to 2C-T-2 and 2C-E in terms of the experience. It’s intensely visual with mild to heavy body load. The higher the dose, the more impact this compound has on the body. This is the main source of discomfort for people using this substance.

The visuals are uniquely 2C-T-X — which are characterized by vivid colors, flowing patterns, and rich geometric patterns. These geometric patterns are sometimes compared to DMT, but they take on a very different character. There’s less symmetry and more complexity with the color.

In terms of potency, 2C-T-7 is on-par with 2C-B, 2C-E, and 2C-I — all of which have the same general dosage range. It’s weaker than 2C-P and other psychedelics like LSD or other lysergamide psychedelics.

The depth of the experience is moderate — sometimes taking people out of the body with a somewhat dissociative tone. This compound doesn’t provide the same level of depth as compounds like psilocybin, LSD, or DMT when used in higher doses without inducing extremely uncomfortable physical side effects.

Is 2C-T-7 Safe?

2C-T-7 has not been tested for safety. It’s been on the research chemical market for several decades, with only a few cases of hospitalizations or deaths. Most of the reports of toxicity from this substance involve insufflation (snorting), taking more than 30 mg, or mixing 2C-T-7 with other stimulants or alcohol.

Testing 2C-T-7 With Harm Reduction Test Kits

One of the core principles of harm-reduction is to test your substances before you take them. This can be done simply and cheaply at home using a reagent drug testing kit.

These tests only require a small sample of the substance in question — roughly the size of a grain of sand. Place the sample on a white ceramic surface and drop one drop of the reagent on the sample. Wait to see the color change.

These tests won’t tell you how potent your substance is, but it can help rule out some of the more dangerous adulterants, such as NBOMes, opiates, or more potent substances (like bromo-dragonFLY or 2C-P).

The main tests to run for 2C-T-7 are the marquis, mecke, and mandolin reagents.

  • Stomach cramping
  • Nausea & vomiting
  • Diarrhea
  • Dizziness
  • Headaches
  • Increased body temperature

Is 2C-T-7 Legal?

No, 2C-T-7 is illegal in virtually all parts of the world. It’s specifically named on the list of restricted chemicals in the United States, Canada, and the United Kingdom.

In Australia and New Zealand, 2C-T-7 isn’t named specifically but is illegal by proxy for being a derivative of known prohibited substances.

Final Thoughts: What’s The Future of 2C-T-7?

2C-T-7 is an obscure phenethylamine psychedelic. It’s likely to remain in obscurity for the foreseeable future.

It’s extremely unlikely this compound will be legalized anytime soon unless a widespread change is made to legalize all psychedelics (also unlikely).

Even as public interest in psychedelics continues to increase, 2C-T-7 isn’t likely to reach mainstream popularity because of its unpredictable nature and high chances of producing negative side effects.

This 2C-X member is likely to remain reserved for only the most adventurous of the psychedelic community.
