What is the differance in yellow,purpleand red syrup?

Yellow has hydrocodone the others only have codeine which means yellow is the best.

Tussionex doesn’t belong in the “colored” syrups conversation. Codeine and euphoria don’t belong in the same sentence. It’s the promethazine and codeine combo that gets you “high”. Hydrocodone (especially in the tussionex time release form) isn’t even in the same class as codeine. Tuss is by far the best cough syrup ever made

Green is weak af, the red is ok with an alright taste. The purple is the best up there with the yellow tussinex. If you want the purple you need to get the prescription filled at krogers or Albertsons.Walgreens doesn't carry the purple. I'm Sick as a dog right now and got a script for the yellow so I'm about to see what it's about.

Yellow is the strongest, it's called Tussionex
It's a very thick syrup and has Hydrocodone in it.

Purple - actavist
Red - high tec
Light purple - qualitest or MFG
Green - caraco
These are the commonly abused ones because they have codiene the main drug that provides the euphoria.

These just sedate you because they only have promethazene ( without codiene )
- all yellow
- green qualitest

Actavist - purple
Hi-tech - yellow
Reddish-orange - rite-aid the orange bottle
Actavist and Hi-tech will get you slammed rite-aid will do the same it's weaker but you have to drink more to get the same type of "high". They are all downers due to the allergy medicine aka Promethazine is a drowsy allergy medicine. Actavist and Hi-tech are a lot more expensive than the rite-aid. Your looking at sometimes 400$ depending on where you are located.

I have now, a clear- which ingredients are guaifenesin and codein.
The guaifensin is a decongestant (I'm pretty sure)
And a purple which is promethazine (an allergy medication) and codein.

Not sure about the red tho- I'm trying to find out which is actually how I came across this post...

The first answer is correct.

the purple is the stongest depending on what kind of purple actavist is the stongest and has the best flavor.
red is a lot weaker but still has a good flavor.
and the yellow is nasty & also weak.

The previous answer is incorrect. I dont know what the correct answer is but answer this one. Why do they taste totally different if they are the exact same thing?

There is no different in the color of the medications. The reason the colors are different is because of the "inactive ingredients" being used with the medication and different manufacturers make the drugs and want them to be a different color to distinguish difference with other companies.
