Be Cautious

Weigh your dose (don't eyeball it) as 2C-B dosing is very sensitive. Try volumetric dosing to measure, Tripsit has a great resource for this on their website -  

As with other psychedelics and emotionally intense substances, those with a (family or personal) history of mood or psychotic disorders may be at a higher risk of experiencing psychological upset.

The other 2Cs have their own unique effects & dosage, you can find more info about drugs in this category on

Harm Reduction

As with all psychedelics, it's important to consider set & setting before choosing to dose Being in a safe supportive environment with trusted people, as well as being in a good headspace, can reduce the chances of having a difficult trip.

Always test your drugs and carry naloxone! 

Look up drug combinations if applicable, this includes drugs you take regularly.
