I have come across some purple mgp promethazine with codeine. I want to put it up on my evo vendor or account or cloud 9. Would this be a product of high demand. I know it is very popular some places but It is also not so popular in many other places.
What's the point? It's codeine with an antihistamine. You can get the same or better effects by finding a good codeine phosphate connect(not that tough, even on the clearnet). The price of codeine cough syrup has been artificially inflated by people who don't understand what it really is.
Last time I saw a bottle, it said that every 5ml (1 teaspoon) contained 10mg codeine. There's about 6 teaspoons in an ounce. So about 60mg codeine per ounce. But my math could be off.
Just as an aside, I live in the southern US (Texas more specifically), outside Houston where the "purple drank" phenomena really took off. You hear people talk about dropping a 'fo (four oz) like it's a huge dose. That's 240mg codiene. That's really not that much compared to what a lot of people are taking recreationally. At that point, you're probably getting more fucked up on promethazine than anything else.
TLDR - Step 1...find a codeine connect. Step 2...take your codeine with an antihistamine. Step 3...take all that money you saved and spend it on something else.
