What does 2C-B look like?

2C-B is best known for being pink, which is the least reliable thing about it. It appears as small pressed pills, as powder that runs from white through pink to beige, and less often as crystal. The colour is a branding choice and has been copied by everything sold under the same name.

The forms it comes in

The table below lists the shapes 2C-B turns up in and what each one actually indicates, which is usually something about processing rather than about quality.

Forms of 2C-B, and what each one does and does not indicate

Form	What it looks like	What it tells you
Small pill	Often tiny, sometimes with a logo	Small size fits a milligram dose, which is a weak hint
Powder	White to pink or beige	Colour is dye or synthesis, not identity
Crystal	Small, off-white	Less common, says nothing extra

Colour

Pink became the signature and is now the problem. Dye is cheap, and pink powder sold as 2C-B has repeatedly turned out to be a cathinone, ketamine, or a mixture. This is the same naming confusion behind tusi, which is usually pink powder containing no 2C-B whatsoever.

Texture and shine

There is little to read. Pills are small and often crudely pressed. Powder is fine and unremarkable. 2C-B is bitter, which people use as a check, and bitterness is shared by most of what replaces it.

What looks the same

Cathinones, ketamine mixtures and sometimes nothing identifiable are sold as 2C-B, particularly in pink powder form. Because the dose is in milligrams, a substitute that needs a different amount is dangerous at the same volume.

What the look does tell you

The size of a genuine 2C-B pill is a real, if weak, signal. A substance active at 10 to 25 milligrams does not need a large pill, so a big pill sold as 2C-B is worth questioning. That is a prompt to test, not a conclusion.

Where looking stops

Nothing above identifies a substance. Appearance cannot tell you which molecule you have, it cannot tell you how much of it is there, and it cannot see the cuts, because the things added to 2C-B are chosen partly for looking like it. Two samples that look identical can be different substances at different strengths.

That is not a reason to give up on knowing. It is the reason chemistry exists, and the steps are quick. A reagent answers what the substance is. A testing card separates the sample and shows what else is in there along with a rough percentage. A laboratory analysis gives you an exact figure when the answer has to be exact.

Questions?

Is pink powder always 2C-B?

No. Pink is dye. Pink powder sold under this name has repeatedly been cathinones or ketamine mixtures.

Is tusi the same as 2C-B?

Usually not. Tusi is pink powder named after the sound of 2C-B and it commonly contains none.

Does bitterness confirm it?

No. Most of the substitutes are bitter too.

Why are the pills so small?

Because the active dose is small. That is consistent with 2C-B but does not identify it.
