It sounds like you're trying to make a lean replacement to sell. Do not advertise this as a replacement or alternative to lean as it is nothing alike being an unresearched research compound unlike codeine with promethazine, both well researched compounds with long standing common medical usage. If you do end up exposing someone else to it please represent it as what it is, a research compound opiate with very little research or history of human use with a much higher risk rating that could very easily lead to a fatal overdose if multiple doses are used at once. That is if you expose anyone else where it's recommended you do not share and honestly should just avoid.
